2. 1 and 2
3. 2 and 3
4. 1, 2 and 3

4. Tropospheric Ozone consists of

1. Sulphur Dioxide
2. Methane
3. Nitrogen Oxides
4. Volatile Organic Compounds
5. Carbon Monoxide

Choose the correct options

1. 1, 2, 4 and 5
2. 2, 3, 4 and 5
3. 1, 2, 3 and 4
4. 1, 2, 3, 4 and 5

5. Consider the following statements regarding ozone depletion

1. Polar Stratospheric Clouds inhibits ozone depletion
2. Ozone depletion will affect human body by enhancing the chances of skin cancer and reduced level of Vitamin D in the body.
3. Montreal Protocol and Vienna Convention are related to Ozone Depleting Substances

Select the wrong statements

1. Only 2
2. 1 and 3
3. 1 and 2
4. Only 1

6. Consider the following

1. Photochemical Smog
2. Acid Rains
3. Death of vegetation
4. Loss of biodiversity in aquatic ecosystem
5. Damage to buildings

Sulphur dioxide contributes to all of the problems mentioned above except

1. Only 1
2. 1 and 3
3. Only 3
4. 3 and 4

7. How do CFCs reduce the concentration of ozone in the atmosphere?

1. Radiation caused CFCs to release atoms that converts ozone to oxygen
2. CFCs splits into troposphere and combine with carbon dioxide to form oxygen
3. CFCs splits into the troposphere and oxidise, preventing the formation of ozone
4. CFCs combine with ozone to produce oxidised molecules

8. Mercury is particularly hazardous to human health because

1. It bioaccumulates high up the food chain.
2. As a heavy metal, it can cause serious impact injury.
3. It is light and volatile, and so is widely dispersed through the environment by wind.
4. As a pure metal it is very soluble in water, hence easily absorbed through drinking water.

9. A high Biological Oxygen Demand indicates

1. Low level of microbial pollution
2. High level of microbial pollution
3. Pure water
4. Absence of microbial action

10. A lichen is best characterized as a symbiosis between

1. Bacteria and Fungus
2. An algae and Bacteria
3. Fungus and an algae
4. An algae and moss

11. Consider the following statements

1. Advanced Heavy Water Reactor is India’s third stage Nuclear programme
2. Thorium will be used as fuel in AWHR
3. Globally, Thorium is more abundant than Uranium

Select the correct option

1. 1 and 2
2. 1, 2 and 3
3. 2 and 3
4. 1 and 3

12. Exploration of Shale gas in India is fraught by several issues. Consider the statements regarding this

1. It will severely affect ground water
2. It will give rise to release of green house gases
3. Hydraulic fracturing causes millions of very small and localized seismic events when the fractures are actually produced in the shale

Select the correct options

1. 1, 2 and 3
2. 2 and 3
3. 1 and 3
4. Only 3

1. Hydrogen fuel cells converts chemical energy into electrical energy
2. They are more environment friendly as compared to other fuels like Coal and Natural gas etc.
3. The only concern is release of CO2 and excess heat after the reaction.

Select the correct codes

1. Only 3
2. 1 and 2
3. 2 and 3
4. 1, 2 and 3

14. Consider the following regarding Coal Gasification

1. Coal gasification produces syngas
2. Coal gasification can be used for making ammonia and methanol
3. Coal gasification produces less carbon dioxide than tradition coal plants

Select the correct options

1. 1 and 2
2. 2 and 3
3. 1 and 3
4. 1, 2 and 3

15. Consider the following
