ANSWERS
1. Ans: c
Justification:
- Nitrogen, which is a vital macronutrient for most plants, is the most abundant element in the atmosphere. A little over 78% of dry air on Earth is nitrogen. But atmospheric nitrogen, or dinitrogen, is unreactive and cannot be utilised by plants directly.
- According to the World Health Organization, nitrate-contaminated drinking water can cause reduced blood function, cancer and endemic goiters. Surplus inputs of nitrogen compounds have been found to cause soil acidification.
2.Ans: a
Justification:
- Natural nitrogen cycle was inadequate to feed the growing population. Scientists Fritz Haber and Carl Bosch solved this problem by producing ammonia by combining atmospheric nitrogen with hydrogen gas at high temperature and pressure—known as the Haber-Bosch process. The Green Revolution, which was instrumental in establishing food security in the developing countries in the 1960s, was driven by artificial nitrogen-fixation. Today, about half of the world’s population depends on this process for its nutrition.
3. Ans: a
Justification:
- The Kaladan River is a river in eastern Mizoram State of India, and in Chin State and Rakhine State of western Myanmar.The Kaladan River is called the Chhimtuipui River in India.
4. Ans: b

- Cyclones in the Indian Ocean
- Hurricanes in the Atlantic
- Typhoons in the Western Pacific and the South China Sea

5. Ans: a
Justification:
- The Kaladan project connects Sittwe Port in Myanmar to the India-Myanmar border.
- The project was jointly initiated by India and Myanmar to create a multi-modal platform for cargo shipments from the eastern ports to Myanmar and to the North-eastern parts of the country through Myanmar.
