Which one of the following Indian states does NOT share international border with two or more countries?
- A.Arunachal Pradesh
- B.Assam
- C.Mizoram
- D.Tripura
Correct answer
Explanation
The correct answer is D, Tripura. Tripura shares an international border with only one country, Bangladesh, which surrounds it on three sides.
Tripura's border with Bangladesh is about 856 km long, and on its remaining side it touches only the Indian states of Assam and Mizoram. The other three states each border two or more countries. Arunachal Pradesh touches Bhutan in the west, China in the north and Myanmar in the east. Assam borders Bhutan and Bangladesh. Mizoram lies between Bangladesh to the west and Myanmar to the east and south.
A is wrong because Arunachal Pradesh shares borders with three countries: Bhutan, China and Myanmar.
B is wrong because Assam shares borders with two countries: Bhutan and Bangladesh.
C is wrong because Mizoram shares borders with two countries: Bangladesh and Myanmar.
Exam tip: Bangladesh touches West Bengal, Assam, Meghalaya, Tripura and Mizoram; Myanmar touches Arunachal Pradesh, Nagaland, Manipur and Mizoram.

1. In the tropical zone, the western sections of the oceans are warmer than the eastern sections owing to the influence of trade winds.
2. In the temperate zone, westerlies make the eastern sections of oceans warmer than the western sections.
Which of the statements given above is/are correct?
- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
Show answer
The prevailing winds push warm surface water west in the tropics and east in the middle latitudes. In the tropics the trade winds blow from east to west.

Statement-I: The soil in tropical rain forests is rich in nutrients.
Statement-II: The high temperature and moisture of tropical rain forests cause dead organic matter in the soil to decompose quickly.
Which one of the following is correct in respect of the above statements?
- A.Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
- B.Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
- C.Statement-I is correct but Statement-II is incorrect
- D.Statement-I is incorrect but Statement-II is correct
Show answer
Rain forest soils are poor in nutrients, even though dead matter decomposes very fast there. In the hot, wet climate of tropical rain forests, fallen leaves and wood are broken down by fungi, bacteria and insects within weeks.

- A.Sugarcane
- B.Sunflower
- C.Pearl millet
- D.Red gram
Show answer
Sugarcane needs far more water to grow than the other three crops, so it is the least water-efficient. Sugarcane stays in the field for 12 to 18 months and needs roughly 1,500 to 2,500 mm of water over its life, often supplied by heavy irrigation.

- A.The total amount of insolation received at the equator is roughly about 10 times of that received at the poles.
- B.Infrared rays constitute roughly two-thirds of insolation.
- C.Infrared waves are largely absorbed by water vapour that is concentrated in the lower atmosphere.
- D.Infrared waves are a part of visible spectrum of electromagnetic waves of solar radiation.
Show answer
Infrared radiation is strongly absorbed by water vapour, and most water vapour lies in the lowest few kilometres of the atmosphere.
