Question 1 of 5
1. Question
Consider the following statements regarding the use of green hydrogen in agriculture:
- Green hydrogen can be used to produce carbon-free ammonia, reducing reliance on fossil fuels for fertilizer production.
- Green hydrogen-powered farm machinery, such as tractors and harvesters, can help reduce greenhouse gas emissions in the agriculture sector.
- Green ammonia produced from green hydrogen increases soil acidity, making it less efficient than traditional fertilizers.
How many of the above statements is/are correct?
Correct
Solution: b)
Statements 1 and 2 are correct. Green hydrogen can be used to produce carbon-free ammonia, reducing the agricultural sector’s dependence on fossil fuels for fertilizer production. This also helps in reducing greenhouse gas emissions. Additionally, green hydrogen can be used to power farm machinery, further decreasing the carbon footprint.
However, statement 3 is incorrect—green ammonia does not increase soil acidity but rather offers improved efficiency compared to traditional ammonia.

2. Question
Consider the following statements regarding hydrogen fuel cells in the transport sector:
- Hydrogen fuel cell vehicles produce zero emissions, emitting only water vapour as a by-product.
- Hydrogen fuel cells offer a longer range and faster refuelling compared to battery electric vehicles.
- Hydrogen fuel cells increase energy consumption compared to traditional combustion engines.
How many of the above statements is/are incorrect?
Correct
Solution: a)
Statements 1 and 2 are correct. Hydrogen fuel cells in vehicles produce zero emissions, making them environmentally friendly. They emit only water vapour as a by-product. Additionally, hydrogen fuel cells provide longer driving ranges and faster refuelling times compared to battery electric vehicles.
However, statement 3 is incorrect because hydrogen fuel cells increase energy efficiency compared to traditional combustion engines, not energy consumption.

3. Question
Consider the following statements about the Nilgiri Biosphere Reserve, of which Mudumalai Tiger Reserve is a part:
- It was the first biosphere reserve established in India.
- It includes areas in Karnataka, Kerala, and Tamil Nadu.
- The reserve supports a large population of the endangered Bengal tiger.
- Nilgiri Biosphere Reserve is entirely made up of deciduous forests.
How many of the above statements is/are correct?
Correct
Solution: c)
- The Nilgiri Biosphere Reserve, established in 1986, was India’s first biosphere reserve, making statement 1 correct.
- It spans across three states—Karnataka, Kerala, and Tamil Nadu—encompassing areas such as the Mudumalai, Bandipur, and Silent Valley reserves, making statement 2 also correct.
- The reserve supports a significant population of the endangered Bengal tiger, especially within its tiger reserves like Mudumalai and Bandipur, thus making statement 3 accurate.
- However, statement 4 is incorrect because the Nilgiri Biosphere Reserve contains a variety of forest types, not just deciduous forests. It includes tropical moist forests, tropical dry forests, and montane shola-grassland ecosystems.
- This rich diversity of habitats contributes to the region’s high biodiversity and status as a crucial ecological zone.
