Q.2) With reference to the Indian economy, consider the following statements:
1. An increase in Nominal Effective Exchange Rate (NEER) indicates the appreciation of rupee.
2. An increase in the Real Effective Exchange Rate (REER) indicates an improvement in trade competitiveness.
3. An increasing trend in domestic inflation relative to inflation in other countries is likely to cause an increasing divergence between NEER and REER.
Which of the above statements are correct?
a) 1 and 2 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and 3
Ans) c
Exp) Option c is the correct answer.
The indices of Nominal Effective Exchange Rate (NEER) and Real Effective Exchange Rate (REER) are used as indicators of external competitiveness.
Statement 1 is correct: NEER is the weighted average of bilateral nominal exchange rates of the home currency in terms of foreign currencies. An increase in Nominal Effective Exchange Rate (NEER) indicates the appreciation of rupee.
Statement 2 is incorrect: REER is the weighted average of nominal exchange rates adjusted for relative price differential between the domestic and foreign countries.
An increase in a nation’s REER is an indication that its exports are becoming more expensive and its imports are becoming cheaper. Means, it is losing its trade competitiveness.
Statement 3 is correct: A real effective exchange rate (REER) is the NEER adjusted by relative prices or costs, typically captured in inflation differentials between the home economy and trading partners. A nation’s nominal effective exchange rate (NEER) when adjusted for inflation in the home country, equals its real effective exchange rate (REER). Higher the inflation higher will be divergence (difference between) NEER and REER.

Q.3) With reference to the Indian economy, consider the following statements:
1. If the inflation is too high, Reserve Bank of India (RBI) is likely to buy government securities.
2. If the rupee is rapidly depreciating, RBI is likely to sell dollars in the market.
3. If interest rates in the USA or European Union were to fall, that is likely to induce RBI to buy dollars.
Which of the statements given above are correct?
a) 1 and 2 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and 3
Ans) B
Exp) Option b is the correct answer.
Statement 1 is incorrect: If the inflation is too high, Reserve Bank of India (RBI) is likely to reduce the money supply in the economy to control inflation. Thus, RBI sells the government securities so as to suck the excess of money supply from the economy and to control the inflation.
Statement 2 is correct: The Reserve Bank of India intervenes in the currency market to support the rupee as a weak domestic unit can increase a country’s import bill. There are a variety of methods by which RBI intervenes. It can intervene directly in the currency market by buying and selling dollars. If RBI wishes to prop up rupee value, then it can sell dollar and when it needs to bring down rupee value, it can buy dollars.
Statement 3 is correct: When the US raises its domestic interest rates, this tends to make India less attractive for the currency trade. As a result, some of the money may be expected to move out of the Indian markets and flow back to the US, therefore decreasing the value of India’s currency against the US dollar. Thus, if interest rates in the USA or European Union were to fall, the value of rupee against the dollar increases and that is likely to induce RBI to buy dollars.

Statement 2 is correct: The Common Framework for debt treatment beyond the DSSI (Common Framework) is an initiative to support, in a structural manner, Low Income Countries with unsustainable debt.

Statement 2 is correct: These instruments protect savings from inflation. It has been decided by the RBI to consider WPI for inflation protection in IIBs.
Statement 3 is incorrect: Extant tax provisions will be applicable on interest payment and capital gains on IIBs. There will be no special tax treatment for these bonds.

Indirect transfers refer to situations where when foreign entities own shares or assets in India, the shares of such foreign entities are transferred instead of a direct transfer of the underlying assets in India. The amendments made in the ITA in 2012 clarified that if a company is registered or incorporated outside India, its shares will be deemed to be or have always been situated in India if they derive their value substantially from the assets located in India. As a result, the persons who sold such shares of foreign companies before the enactment of the Act (i.e., May 28, 2012) also became liable to pay tax on the income earned from such sale.

Deposits with banks are the single largest form of households’ financial assets, followed by insurance funds, mutual funds and currency. Therefore, any adverse movement in the household savings will have a significant bearing on banks, insurance companies and mutual/provident funds, who, in turn, are key investors in government securities.
Statement 2 is correct: Internal debt constitutes over 93 per cent of the overall public debt. Internal loans that make up for the bulk of public debt are further divided into two broad categories – marketable and non-marketable debt.
The sources of public debt are dated government securities (G-Secs), treasury bills, external assistance, and short-term borrowings.

Q.21) Among the following crops, which one is the most important anthropogenic source of both methane and nitrous oxide?
a) Cotton
b) Rice
c) Sugarcane
d) Wheat
Ans) B
Exp) Option b is the correct answer.
Methane and nitrous oxide are important greenhouse gases. They contribute to global warming. Important anthropogenic sources of biogenic methane are wet rice fields, cattle, animal waste, landfills and biomass burning.
Flooded rice cultivation has been identified as one of the leading global agricultural sources of anthropogenic methane (CH4) emissions. Furthermore, it has been estimated that global rice production is responsible for 11% of total anthropogenic CH4 emissions.
Paddies are a potential source of anthropogenic nitrous oxide (N2O) emission as well. In paddies, both the soil and the rice plants emit N2O into the atmosphere. The rice plant in the paddy is considered to act as a channel between the soil and the atmosphere for N2O emission.
https://www.intechopen.com/chapters/49649
Q.22) “System of Rice Intensification” of cultivation, in which alternate wetting and drying of rice fields is practised, results in:
1. Reduced seed requirement
2. Reduced methane production
3. Reduced electricity consumption
Select the correct answer using the code given below:
a) 1 and 2 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and 3
Ans) D
Exp) Option d is the correct answer.
The System of Rice Intensification involves cultivating rice with as much organic manure as possible. It employs
- young seedlings planted singly at wider spacing in a square pattern; and
- with intermittent irrigation that keeps the soil moist but not inundated, and
- frequent inter cultivation with weeder that actively aerates the soil.
System of Rice Intensification (SRI) includes a method called Alternate Wetting and Drying (AWD) which is a form of controlled or intermittent irrigation of the rice crops.
SRI methods have the following benefits and impacts, in general, compared to conventional methods of paddy cultivation:
- To increase paddy yields usually by 20-50% and sometimes up to 100%
- It reduces required seeds for transplanting by 60-80%( Hence Option 1 is correct);
- The electricity consumption will be less as it enables reduce use of chemical fertilizers and agrichemicals and reduced use of irrigation water by 25-50% ( Hence Option 3 is correct);
Option 2 is correct. By stopping flooding and relying mostly on organic fertilization, methane emissions are greatly reduced without offsetting increases in nitrous oxide. Also, less carbon dioxide is generated due to reduced reliance on and transport of manufactured inputs. Oxford researchers in India found 30% reduction in net greenhouse gas emissions with SRI, compared with current practice, and more than 50% reduction in greenhouse gas emissions per kilogram of rice produced.

c) 1, 3, 4, 6 and 7 only
d) 1, 2, 3, 4, 5, 6 and 7
Ans) C
Exp) Option c is the correct answer.
Solar flares are intense bursts of radiation from the sun that can directly influence electronics on Earth. They are often associated with coronal mass ejections (CMEs), which are large clouds of gas that erupt from the sun’s interior into its atmosphere.
Statement 1 and 3 are correct: The large solar flare is projected to strike satellites in the Earth’s upper atmosphere. Thus it affects GPS navigation, mobile phone transmissions, and satellite TV. The flares might potentially disrupt power grids and electrical networks in various regions of the planet.
Statement 2 is incorrect: Solar flares can temporarily alter the upper atmosphere creating disruptions. But it does not cause Tsunamis. It only affects the upper atmosphere.
Statement 4 is correct: The high-energy particles emitted by the flare could also cause certain atoms in the Earth’s atmosphere to glow, leading to auroras in Central Europe as well as North America. The phenomenon could only be seen if the weather is clear.
Statement 5 is incorrect: There is no causal link between the coronal mass ejections (CMEs) and the deadly forest fires. There is a common misconception that solar storms are associated with extreme geological and atmospheric effects on Earth. The sun cannot produce solar flares or CMEs that physically burn the landscape, if it did, I doubt complex life would have had much of a chance at evolving over the last few billion years if our planet was constantly being sterilized.
Statement 6 is correct: The scientists found that solar flares and storms heated and expanded the atmosphere and that these effects could extend to the satellites’ orbits. The density of atmospheric gases increases, slowing the satellites and causing them to lose altitude by a few kilometres per day.
Statement 7 is correct: Solar flares allow interference with the short wave radios that are being used, emitting more rays allowing people to get more of a sun burn during this time frame.
A study by NASA of polar flights during a solar storm in 2003 showed that passengers received about 12 percent of the annual radiation limit recommended by the International Committee on Radiological Protection. The exposures were greater than on typical flights at lower latitudes, and confirmed concerns about commercial flights using polar routes.

Q.43) “If rainforests and tropical forests are the lungs of the Earth, then surely wetlands function as its kidneys.” Which one of the following functions of wetlands best reflects the above statement?
a) The water cycle in wetlands involves surface runoff, subsoil percolation and evaporation.
b) Algae form the nutrient base upon which fish, crustaceans, molluscs, birds, reptiles and mammals thrive.
c) Wetlands play a vital role in maintaining sedimentation balance and soil stabilization.
d) Aquatic plants absorb heavy metals and excess nutrients.
Ans) D
Exp) Option d is the correct answer.
Just as forests are called as the ‘lungs of the earth’, wetlands are the ‘kidneys’ that regulate water and filter waste from the landscape.
Wetlands include mangroves, peat lands and marshes, rivers and lakes, deltas, floodplains and flooded forests, rice-fields, and even coral reefs. Aquatic plants of wetlands absorb heavy metals and excessive nutrients thereby purifying water. For instance, Mangrove trees have the ability of storing metals, transferring these elements from the sediment and concentrating them in their tissues . They can serve as a means for the immobilization and removal of pollutants.

Exp) Option b is the correct answer.
Statement 1 is correct:The World Health Organization(WHO) has released the Global Air Quality Guidelines(AQGs).The new guidelines recommend air quality levels for six pollutants particulate matter (PM) 2.5 and PM 10, ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2) and carbon monoxide (CO).
Statement 2 is incorrect: Ozone at ground level is formed by the reaction with sunlight (photochemical reaction) of pollutants such as nitrogen oxides (NOx) from vehicle and industry emissions and volatile organic compounds (VOCs) emitted by vehicles, solvents and industry. As a result, the highest levels of ozone pollution occur during periods of sunny weather and not during inclement weather.
Statement 3 is incorrect: PM is a common proxy indicator for air pollution. It affects more people than any other pollutant. The major components of PM are sulfate, nitrates, ammonia, sodium chloride, black carbon, mineral dust and water. It consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air. While particles with a diameter of 10 microns or less, (≤ PM10) can penetrate and lodge deep inside the lungs, the even more health-damaging particles are those with a diameter of 2.5 microns or less, (≤ PM2.5). PM2.5 can penetrate the lung barrier and enter the blood system. Chronic exposure to particles contributes to the risk of developing cardiovascular and respiratory diseases, as well as of lung cancer.
Statement 4 is correct: Excessive ozone in the air can have a marked effect on human health. It causes breathing problems, trigger asthma, reduce lung function and cause lung diseases. Ozone triggers asthma because it is very irritating to the lungs and airways.

Q.46) With reference to polyethylene terephthalate, the use of which is so widespread in our daily lives, consider the following statements:
1. Its fibres can be blended with wool and cotton fibres to reinforce their properties.
2. Containers made of it can be used to store any alcoholic beverage.
3. Bottles made of it can be recycled into other products.
4. Articles made of it can be easily disposed of by incineration without causing greenhouse gas emissions.
Which of the statements given above are correct?
a) 1 and 3
b) 2 and 4
c) 1 and 4
d) 2 and 3
Ans) A
Exp) Option a is the correct answer.
Polyethylene terephthalate (PET or PETE) is a strong, stiff synthetic fibre and resin and a member of the polyester family of polymers. PET is spun into fibres for permanent-press fabrics and blow-molded into disposable beverage bottles.
Statement 1 is correct: PET fibres make them highly resistant to deformation, so they impart excellent resistance to wrinkling in fabrics. They are often used in durable-press blends with other fibres such as rayon, wool, and cotton, reinforcing the inherent properties of those fibres while contributing to the ability of the fabric to recover from wrinkling.
Statement 2 is incorrect: Maharashtra government has announced the ban on sale of alcohol in PET bottles from April 1. Plastic packaging is dangerous to human health and the country liquor and country made foreign liquor cannot be sold in such bottles. PET has become widely used in carbonated-beverage bottles and in jars for food processed at low temperatures. The low softening temperature of PET—approximately 70 °C (160 °F)—prevents it from being used as a container for hot foods.
Statement 3 is correct: Polyethylene terephthalate is the most widely recycled plastic. For instance, PET bottles and containers are commonly melted down and spun into fibres for fibrefill or carpets.
Statement 4 is incorrect: Polyethylene, like other plastics, is not inert and is known to release additives and other degradation products into the environment throughout its lifetime. For example, the additive bisphenol-A used in the manufacture of many plastic products is leached as plastics age, and hydrocarbon gases are produced during high-temperature decomposition (>202°C).

Q.49) “Biorock technology” is talked about in which one of the following situations?
a) Restoration of damaged coral reefs
b) Development of building materials using plant residues
c) Identification of areas for exploration/extraction of shale gas
d) Providing salt licks for wild animals in forests/protected areas
Ans) A
Exp) Option a is the correct answer.
The Zoological Survey of India (ZSI), with help from Gujarat’s forest department, is attempting for the first time a process to restore coral reefs using bio rock or mineral accretion technology. A bio rock structure was installed one nautical mile off the Mithapur coast in the Gulf of Kachchh on January 19.
- Bio rock is the name given to the substance formed by electro accumulation of minerals dissolved in seawater on steel structures that are lowered onto the sea bed and are connected to a power source, in this case solar panels that float on the surface.
- The technology works by passing a small amount of electrical current through electrodes in the water. When a positively charged anode and negatively charged cathode are placed on the sea floor, with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode). This results in calcium carbonate formation. Coral larvae adhere to the CaCO3 and grow quickly.
Q.50) The “Miyawaki method” is well known for the:
a) Promotion of commercial farming in arid and semi-arid areas
b) Development of gardens Using genetically modified flora
c) Creation of mini forests in urban areas
d) Harvesting wind energy on coastal areas and on sea surfaces
Ans) C
Exp) Option c is the correct answer.
Bombay Municipal Corporation (BMC) has been using the Miyawaki method to create tiny urban forests in the Metropolitan areas of Mumbai. Miyawaki is an afforestation method based on the work of Japanese botanist Akira Miyawaki in the 1980s.
Process of Miyawaki Method:
- Initially, native trees of the region are identified and divided into four layers- shrub, sub-tree, tree, and canopy.
- After that, the quality of soil is analyzed and biomass is mixed with it. Biomass mixing help to enhance the perforation capacity, water retention capacity, and nutrients.
- A mound is built with the soil and the seeds are planted at a very high density. Furthermore, the ground is covered with a thick layer of mulch.
- Multi-layered saplings are planted close to each other. This blocks sunlight from reaching the ground and prevents weeds from growing. It also keeps the soil moist.
- The close cropping also ensures that the plants receive sunlight only from the top. It enables them to grow upwards rather than sideways.

2. During the reign of Ala-ud-din Khalji, one Mongol assault marched up to Delhi and besieged the city.
3. Muhammad-bin-Tughlaq temporarily lost portions of north-west of his kingdom to Mongols.
Which of the statements given above is/are correct?
a) 1 and 2
b) 2 only
c) 1 and 3
d) 3 only
Ans) B
Exp) Option b is the correct answer.
Statement 1 is incorrect: The first Mongol invasion of India took place in the reign of Sultan Shams-ud-din lltutmish.
Statement 2 is correct: Alauddin established a huge permanent, standing army to satisfy his ambition of conquest and to protect the country from Mongol invasion.
The Mongols attacked at the worst time possible for Alauddin Khilji – when he was busy laying siege to Chittor. This time the Mongols traveled light. An army of 12,000 under Targhi’s leadership moved to Delhi in a swift attack; many governors could not send their troops to Delhi in time.
Alauddin Khilji was forced to retreat to Siri for about two months. The Mongols attacked and pillaged not only the surrounding areas, but Delhi itself. Alauddin Khilji continued to hold the fortress at Siri; Targhi withdrew the siege after a few months and left the area. Barani, a contemporary historian at that time, attributed this “marvel” to the prayers of the Sufi mystic Shaikh Nizamuddin Auliya.
Statement 3 is incorrect:
The next major Mongol invasion took place after the Khiljis had been replaced by the Tughlaq dynasty in the Sultanate. In 1327 the Chagatai Mongols under Tarmashirin, who had sent envoys to Delhi to negotiate peace the previous year, sacked the frontier towns of Lamghan and Multan and besieged Delhi. The Tughlaq ruler paid a large ransom to spare his Sultanate from further ravages. Muhammad bin Tughluq asked the Ilkhan Abu Sa’id to form an alliance against Tarmashirin, who had invaded Khorasan, but an attack didn’t materialize.Tarmashirin was a Buddhist who later converted to Islam. Religious tensions in the Chagatai Khanate were a divisive factor among the Mongols.

a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
Ans) C
Exp: Option c is the correct answer.
A convertible bond is a type of debt security that provides an investor with a right or an obligation to exchange the bond for a predetermined number of shares in the issuing company at certain times of a bond’s lifetime. It is a hybrid security that possesses features of both debt and equity.
Statement 1 is correct: Convertible bonds tend to offer a lower coupon rate or rate of return in exchange for the value of the option to convert the bond into common stock. Investors will generally accept a lower coupon rate on a convertible bond, compared with the coupon rate on an otherwise identical regular bond, because of its conversion feature. This enables the issuer to save on interest expenses, which can be substantial in the case of a large bond issue.
Statement 2 is correct: The option to convert to equity affords the bondholder a degree of indexation to rising consumer prices as equity prices can differ widely from the given interest and the difference in that can be used as a hedge for the inflation.

Statement 3 is incorrect: According to Wildlife Protection Act, 1972, only if the wild animal becomes a danger to human life or is diseased or disabled beyond recovery can it be allowed to be captured or killed by the competent authority, the Chief Wildlife Warden of the State. This provision is applicable to wild animals listed in Schedule I of the Wildlife (Protection) Act, 1972, which includes leopards. Mere apprehension or fear that a wild animal could endanger human life is not a ground for capture or killing.

b) Only two pairs
c) Only three pairs
d) All four pairs
Ans) B
Exp) Option b is the correct answer.
The Chandellas of Bundelkhand trace their descent to a mythical ancestor named Chandratreya, born of the moon. The Chandellas initially ruled as feudatories of the Gurjara−Pratiharas of Kannauj, and were involved in conflicts with the Pratiharas, the Palas, and the Kalachuris of Chedi (who bordered the Chandellas on the south).
Pair 1 is correct and pair 2 is incorrect: In the first quarter of the 9th century CE, the Chandella dynasty was founded by Nannuka, who was the ruler of a small kingdom and established his capital at Kharjjuravahaka (Khajuraho).
Jayashakti and Vijayashakti (c. 865−885 CE) Vakpati’s sons Jayashakti (Jeja) and Vijayashakti (Vija) consolidated the Chandella power.
Pair 3 is correct The Pratiharas were also known as the Gurjara−Pratiharas, as they originated from the Gurjaras who were primarily pastoralists and fighters. Nagabhata II (reigned c. 793–833) was Vatsaraja’s successor, he reorganized Pratihara power, attacked Kannauj. However, soon afterward he was defeated by the Rashtrakuta king Govinda III (reigned 793–814). Nagabhatta II was succeeded by his son Ramabhadra, who ruled briefly, and was succeeded, by his son Mihira Bhoja.

Q.93) Which one of the following statements about Sangam literature in ancient South India is correct?
a) Sangam poems are devoid of any reference to material culture.
b) The social classification of Varna was known to Sangam poets.
c) Sangam poems have no reference to warrior ethic.
d) Sangam literature refers to magical forces as irrational.
Ans) B
Exp) Option b is the correct answer
sangam literature are the earliest writings in the Tamil language, thought to have been produced in three chankams, or literary academies, in Madurai, India, from the 1st to the 4th century CE.
Statement a is incorrect. Sangam poems contain several incidental references to material culture, often as part of the poem’s setting or in similes and allusions. There are references to farming (rice and barley are mentioned), cattle rearing, and fishing. There are also several references to iron. Kuruntokai 16 refers to iron-tipped arrows. Akananuru 72 compares a bear digging out the comb from a termite mound, the front of which is swarming with fireflies glimmering like sparks from beaten metal, to a blacksmith forging iron.
Statement b is correct. The social classification of varna was known to Sangam poets. There is mention of the Arashar (kings), Vaishiyar (traders), and Velalar (farmers). The Brahmanas are also mentioned, some of them closely associated with the courts of kings and patronized by ruling elites. However, the four-fold varna classification had little application to ancient Tamil society. The jati system was not a feature of this society either.
Statement c is incorrect. Sangam Poems are pervaded with a warrior ethic. Puram in sangam litrauture are the War Poems that deals with the outer life of people. Speak of public celebration of the feats of the heroes even the death of heroes in wars.
Statement d is incorrect. Sangam literature reflects a belief in sacred or magical forces called ananku that were supposed to inhabit various objects. The job of carrying out rites and rituals to control the ananku was that of groups such as the pariyans, tutiyans, panas and velans. They were associated with ritualistic singing, dancing, and trances, and with lighting the cremation fire and worshipping memorial stones.
Q.94) “Yogavasistha” was translated into Persian by Nizamuddin Panipati during the reign of:
a) Akbar
b) Humayun
c) Shajahan
d) Aurangzeb
Ans) A
Exp) Option a is the correct answer.
Coinciding with the foundation of Ibadat Khana, Akbar established his translation bureau (maktab khana) in 1574-1575 at Fathpur Sikri and attached it to the royal library. Largely Sanskrit texts were translated into Persian. However, Persian translations of some Arabic and Turkish texts were also carried out. The translation project in Akbar’s court probably began in 1575-1576 with the arrival of Shaikh Bhawan, a Brahman convert, to Akbar’s court.
Nizam Panipati translated Yogavasistha (a treatise on Vedantic philosophy) as an appendix to Ramayana and dedicated it to Prince Salim during the Akbars reign.

Q.95) The world’s second tallest statue in sitting pose of Ramanuja was inaugurated by the Prime Minister of India at Hyderabad recently. Which one of the following statements correctly represents the teachings of Ramanuja?
a) The best means of salvation was devotion.
b) Vedas are eternal, self-existent and wholly authoritative.
c) Logical arguments were essential means for the highest bliss.
d) Salvation was to be obtained through meditation.
Ans) A
Exp) Option a is the correct answer.
Ramanuja was deeply influenced by the Alvars. He firmly believed that intense devotion to Vishnu was the best means to attain salvation. He propounded the doctrine of Vishishtadvaita.
- The outdoor 216-ft Statue of Equality will be the world’s second tallest statue featuring a sitting posture. It is composed of ‘panchaloha’, a combination of five metals comprising gold, silver, copper, brass, and zinc. Born in 1017 in Sri Perumbudur, Tamil Nadu, Sri Ramanujacharya liberated millions from social, cultural, gender, educational and economic discrimination with the foundational conviction that every human is equal regardless of nationality, gender, race, caste, or creed.

Q.96) The Prime Minister recently inaugurated the new Circuit House near Somanath Temple at Verval. Which of the following statements are correct regarding Somnath Temple?
1. Somnath Temple is one of the Jyotirlinga shrines
2. A description of Somnath Temple was given by Al-Biruni.
3. Pran Pratistha of Somnath Temple (installation of the present-day temple) was done by President S. Radhakrishnan.
Select the correct answer using the code given below:
a) 1 and 2 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and 3
Ans) A
Exp) Option a is the correct answer.
Statement 1 is correct. Located at Veraval in the western coast of Gujarat, the Somnath Temple is believed to be the first among the 12 jyotirlinga shrines of Shiva. The site, which was part of the erstwhile princely state of Junagadh, was also connected to Lord Krishna. The political history of the shrine is traced back to a thousand years when in 1024 CE, during the reign of the Chalukya king Bhima I it was attacked by Turkik ruler Mahmud of Ghazni.
Statement 2 is correct. A description of the temple by Al-Biruni, an Arab traveller, was so glowing that it prompted a visit in 1024 by Mahmud of Ghazni.
Statement 3 is incorrect. The later sources of history account for several desecrations by Muslims invaders during eleventh to eighteen century A.D. The temple was rebuilt every time with the reconstructive spirit of the people. The modern temple was reconstructed with the resolve of Sardar Patel who visited the ruins of Somnath temple on November 13 1947. Then President of India, Dr. Rajendra Prasad, did the Pran-Pratistha at the existing temple on 11 May 1951.

Q.97) Which one of the following statements best describes the role of B cells and T cells in the human body?
a) They protect the body from environmental allergens.
b) They alleviate the body’s pain and inflammation.
c) They act as immunosuppressants in the body.
d) They protect the body from the diseases caused by pathogens.
Ans) D
Exp) Option d is the correct answer
Lymphocytes are a type of white blood cells. They play a critical role in keeping us healthy. Without them, we can’t survive.
- T cells protect us from infection. In our daily lives, we’re constantly exposed to pathogens, such as bacteria, viruses and fungi. Without T lymphocytes, also called T cells, every exposure could be life-threatening. T cells can wipe out infected or cancerous cells. They also direct the immune response by helping B lymphocytes to eliminate invading pathogens.
- B cells create antibodies. B lymphocytes, also called B cells, create a type of protein called an antibody. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection. B cells can also recruit other cells to help destroy an infected cell.
Q.98) Consider the following statements:
1. Other than those made by humans, iianoparticles do not exist in nature.
2. Nanoparticles of some metallic oxides are used in the manufacture of some cosmetics.
3. Nanoparticles of some commercial products which enter the environment are unsafe for humans.
Which of the statements given above is/are correct?
a) 1 only
b) 3 only
c) 1 and 2
d) 2 and 3
Ans) D
Exp) Option d is the correct answer.
Statement 1 is incorrect: Naturally occurring nanoparticles can be found in volcanic ash, ocean spray, fine sand and dust, and even biological matter (e.g. viruses). Synthetic nanoparticles are equally, if not more diverse than their naturally occurring counterparts.
Statement 2 is correct: The field of nanotechnology is being greatly explored by cosmetic industries in order to improve the efficacy of cosmetic products. The cosmetics are formulated by using different types of metal and metal oxide nanoparticles such as silver nanoparticles (AgNPs), gold nanoparticles (AuNPs) and titanium dioxide nanoparticles (TiO2 NPs), zinc oxide nanoparticles, (ZnO NPs), iron oxide nanoparticles, (Fe2O3 NPs) and carbon-based NPs. The applications of different metal oxides as one of the active ingredients in cosmetics and sunscreens have attracted enormous interest from cosmetologists with advanced knowledge of chemistry, toxicology, dermatology, rheology, and even marketing.
Statement 3 is correct: According to the National Nanotechnology Initiative thousands of tons of silica, alumina and ceria, in the form of ultrafine abrasive particle mixtures including nanoparticles, are used each year in slurries for precision polishing of silicon wafers. The exposed population to nano materials continues to increase as their application expands. Despite obvious benefits of the power of small materials, there are open questions about how the nanoparticles used for day-to-day life may affect the environment. One of the crucial issues that have to be addressed in the near future, before massive fabrication of nano materials, is their toxicity to humans and impact on the environment.

Q.99) Consider the following statements:
DNA Barcoding can be a tool to:
1. Assess the age of a plant or animal.
2. Distinguish among species that look alike.
3. Identify undesirable animal or plant materials in processed foods.
Which of the statements given above is/are correct?
a) 1 only
b) 3 only
c) 1and 2
d) 2 and 3
Ans) D
Exp) Option d is the correct answer.
DNA barcoding is a molecular technology that allows the identification of any biological species by amplifying, sequencing and querying the information from genic and/or intergenic standardized target regions belonging to the extranuclear genomes
Option 1 is incorrect: Geologists use the radiometric dating of uranium and the isotopes of other radioactive elements, combined with observations of fossils and sediment layers, to chart the course of Earth’s natural history and the evolution of life. To measure the age of plant and animal remains from the more recent past, scientists use a radioactive isotope of carbon, called carbon-14, as their clock. As carbon-14 decays, with a half-life of about 5,730 years, it becomes nitrogen-14. Using this clock, they have dated bones, campfires and other objects as old as 60,000 years, and in some cases even older.
Option 2 is correct: DNA barcodes allow non-experts to objectively identify species – even from small, damaged, or industrially processed material. Just as the unique pattern of bars in a universal product code (UPC) identifies each consumer product, a “DNA barcode” is a unique pattern of DNA sequence that can potentially identify each living thing.
Option 3 is correct. cpDNA and mtDNA barcoding protocols are being used more and more in the food industry and food supply chains for food labeling, not only to support food safety but also to uncover food piracy in freshly commercialized and technologically processed products. DNA barcoding helps to identify undesirable animal or plant materials in processed foods.

Q.100) Consider the following:
1. Carbon monoxide
2. Nitrogen oxide
3. Ozone
4. Sulphur dioxide
Excess of which of the above in the environment is/are cause(s) of acid rain?
a) 1, 2 and 3
b) 2 and 4 only
c) 4 only
d) 1, 3 and 4
Ans) B
Exp) Option b is the correct answer.
The pollutants, Sulphur dioxide, nitrogen oxide which are released by burning of coal and petroleum products combine with moisture in ‘the air and rain water and produce Sulphuric acid and nitric acid respectively and fall along with the rain called as acid rain. The acid rain pollute soil, water and reduces the growth of crops and fishes in river, streams, canals and ponds. It also stops the growth of plants and destroys: the buildings made of marble and stones and statues made up of metals, Acid rain can cause respiratory problems such as asthma, bronchitis and emphysema.
