10000 Questions for Prelims 2020 | Prelims 2020 Marathon
Dear Friends,
Let is share and post / paste here questions of various test series . If we crowd source enough, we know that questions will come from here. There was a thread of crowd sourced questions in the past, where @wunwun @burger @pizza and all had contributed and that year we had many questions come from there.
Let us start this initiative. Also please follow the convention followed last year by @neyawn Sir, let us number the questions in a serial number.
Here I am starting
#1Choose correct statements
1) M N Roy was the founder of Communism in India
2) M N Roy first mooted the idea of Constituent Assembly
3) Patel was the Chairman of Committee on negotiating with states
4) Nehru was the Chairman of Drafting Committee
Select correct
a) 1 and 2 only
b) 2 and 3 only
c) 2 and 4 only
d) None of t
With reference to the 'Coriolis Force', consider the following statements:1. Coriolis force affects both the wind direction and the wind speed.2. Coriolis Effect is only seen in the Earth and not in other planets of the solar system.Which of the statement(s) given above is/arecorrect?(a) 1 only(b) 2 only(c) Both 1 and 2(d) Neither 1 nor 2D? Coriolis effect is due to rotation, so it must be present in other planets as well?
Correct.
Jupiter has the fastest rotation in the solar system. On Jupiter, the Coriolis effect actually transforms north-south winds into east-west winds.
Which of the following are the reasons for the low salinity of ocean waters near the Equator?1. Heavy rainfall2. High rate of evaporation3. Huge quantities of water brought to oceansby the riversSelect the correct answer from the codes given below.(a) 1 only(b) 2 and 3 only(c) 1 and 3 only(d) 1, 2 and 3A? High rate of evaporation increases salinity. And rivers are not present throughout the equator.
Correct
While moving from Goa to Puducherry, you willpass through which of the following type of vegetation?1. Tropical Evergreen Forest2. Tropical Deciduous Forest3. Tropical Thorn Forest4. Littoral and Swamp ForestSelect the correct answer from the codes givenbelow:a. 1 and 2 onlyb. 1, 2 and 4 onlyc. 2 and 4 onlyd. 1, 2, 3 and 4D. All these types of forests can be seen in Goa itself!
Correct
In recent years,there is a tendency for the sugarmills to concentrate in the southern and westernstates of India. In this context, which of thefollowing is/are the correct reasons?1. The cane produced in these states have a higher sucrose content.2. The cooler climate also ensures a longer crushing season for the producers.3. The cooperatives are more successful in these states.Select the correct answer from the codes given below:a. 1 and 2 onlyb. 2 and 3 onlyc. 1 and 3 onlyd. 1, 2 and 3C. Eliminating statement 2 since there are warmer climates.
It's D. One drawback of sugar industries in the north and price volatility was that it has a very short crushing season (3-4 months of winters). So the mills have a very narrow window in northern states.
D is correct.
India stands second as a world producer of sugar but occupies the first place in the production of gur and khandsari. The raw material used in this industry is bulky, and in haulage its sucrose content reduces. The mills are located in Uttar Pradesh, Bihar, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Gujarat, Punjab, Haryana and Madhya Pradesh. Sixty per cent mills are in Uttar Pradesh and Bihar. In recent years, there is a tendency for the mills to shift and concentrate in the southern and western states, especially in Maharashtra, This is because the cane produced here has a higher sucrose content.
The cooler climate also ensures a longer crushing season.
Consider the following statements:1. The places east of Greenwich Meridian willbe ahead of Greenwich time and those in westwill be behind it.2. In India, the time difference between twoplaces is maximum of one hour.Which of the statement(s) given above is/are correct?(a) 1 only(b) 2 only(c) Both 1 and 2(d) Neither 1 nor 2
A. In India maximum time difference is 2 hours
Undine,
The main reason that the Earth experiences highest temperature in the sub-tropics in the Northern Hemisphere rather than at Equator is:(a) Sub-tropical areas tend to have less cloudcover than equatorial areas.(b) Sub-tropical areas have longer day hours inthe summer than the equatorial.(c) Sub-tropical areas have an enhancedgreenhouse effect compared to equatorialareas.(d) Sub-tropical areas are nearer to the oceanicareas than the equatorial locations.
B? Not sure

A
Time-saving trick when the mind is numb in the exam to remember all the working:
If B was the main reason, then temperate should have a higher temperature. And polar, even higher.

Yeah. I was thinking A and B. But A and C seemed similar. When there's less cloud cover, there's more energy absorbed by Earth and hence more energy released which increases the greenhouse effect.

Hi, I get what you're saying. But what you're referring to, is just more radiation (irrespective of the enhanced greenhouse effect).
I think that could be more like the effect, not the reason in the first place.
