Read the following passage and answer the questions that follow based on your understanding of the passage:
For many people who live in cities, parks are an important part of the landscape. They provide a place for people to relax and play sports, as well as a refuge from the often harsh environment of a city. What people often overlook is that parks also provide considerable environmental benefits, one of which is that plants absorb carbon dioxide (a pollutant) and emit oxygen (that we breathe).
Unfortunately, many cities cannot easily create more parks because most land is already being used for buildings, roads, parking lots, and other essential parts of the urban environment. However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens. While most people would not think of starting a garden on their roof, human beings have been planting gardens on rooftops for thousands of years. Some rooftop gardens are very complex and require complicated engineering, but others are simple container gardens that anyone can create with the investment of a few hundred rupees and a few hours of work. Rooftop gardens provide many of the same benefits as other urban park and garden spaces, but without taking up the much-needed land. Like parks, rooftop gardens help to replace carbon dioxide in the air with nourishing oxygen. They also help to lessen the Urban Heat Island Effect, which can save people money. In the summer, rooftop gardens prevent buildings from absorbing heat from the sun, which can significantly reduce cooling bills. In the winter, gardens help hold in the heat that materials like brick and concrete radiate so quickly, leading to savings on heating bills. Rooftop vegetable and herb gardens can also provide fresh food for city dwellers, saving them money and making their diets healthier. Rooftop gardens are not only something everyone can enjoy, they are also a smart environmental investment.

(A) Parks are expensive to create while rooftop gardens are not.
(B) Parks are public while rooftop gardens are private.
(C) Parks absorb heat while rooftop gardens do not.
(D) Parks require much space while rooftop gardens do not.
Question 3
Based on the passage, it can be inferred that the author would most likely endorse a programme that
(A) Permits the construction of buildings in park-land provided they have rooftop gardens.
(B) Extends discounts on sale of plants to customers who use them to create rooftop gardens.
(C) Offers free admission to schools willing to take their students on field trips to city parks.
(D) Encourages the tearing down of buildings in cities to make space for establishment of parks.
Question 4
Which of the following is not an advantage of rooftop gardens as mentioned in the passage?
(A) They help in heat management.
(B) They can provide food for kitchens.
(C) They make the rooftops beautiful.
(D) They enrich breathable air by absorbing carbon dioxide and giving oxygen.
Question 5
What could be the meaning of “Urban Heat Island” mentioned in the passage?
(A) That clearing of greenery and construction of buildings makes urban areas considerably hotter than surrounding rural areas.
(B) That only islands are for suited for creation of urban areas.
(C) That people in urban areas are spared excess spending of money in summers, because they use ACs and coolers.
(D) That people migrate from urban to rural areas in summer because of the excessive heat, creating a spiralling island of radiation from the urban to the rural areas.

Explanations
1. 2. 3. Suresh is at 5th from left. Given, Tejesh will sit at one end. And also that Ramesh will sit four chairs to the left of Tejesh. If Tejesh is at the leftmost chair, then Ramesh caanot sit to left of Tejesh. So, Tejesh has to be on the rightmost chair. If Tejesh is at 6th from left, the Ramesh will be 2nd from left. Thus, the following diagram can be drawn:
Note that Rakesh’s position is not known and he could be sitting either in the 1st chair or the 4th chair.
In question 3, if someone has to sit in the 4th chair, it will be Rakesh.
4. The possible routes from city A to city C via B = 3 x 2 = 6 routes.
The possible routes from city A to city C via city D = 4 x 3 = 12 routes.
So, total possible routes = 6+12 = 18
5. Simple enough. No explanation needed.
