NTA NET Questions answers

Question 1 Explanation: 
Greenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth's surface and reradiating it back to Earth's surface, thus contributing to the greenhouse effect. Carbon dioxide, methane, and water vapour are the most important greenhouse gases. (To a lesser extent, surface-level ozone, nitrous oxides, and fluorinated gases also trap infrared radiation.) Greenhouse gases have a profound effect on the energy budget of the Earth system despite making up only a fraction of all atmospheric gases. Concentrations of greenhouse gases have varied substantially during Earth's history, and these variations have driven substantial climate changes at a wide range of timescales. In general, greenhouse gas concentrations have been particularly high during warm periods and low during cold periods. These gases have a high capacity for absorbing infrared radiation or occur in significant quantities, whereas others have considerably lower capacities for absorption or occur only in trace amounts.
Question 2
With reference to Dam Rehabilitation and Improvement Project (DRIP), consider the following statements:
  1. The project has been initiated by the government with financial assistance from the World Bank.
  2. Apart from rehabilitation of dams it also strengthens the dam safety institutional setup of participating states.

Question 2 Explanation: 
The Dam Rehabilitation and Improvement Project (DRIP) has been taken up with loan assistance of the World Bank for rehabilitation and improvement of about 250 dams initially in seven States (namely Jharkhand, Karnataka, Kerala, Madhya Pradesh, Odisha, Tamil Nadu, and Uttarakhand) and institutional strengthening and project management in Central Water Commission (CWC) and other Implementing Agencies. Thus, statement 1 is correct.

The project aims to improve the safety and operational performance of selected existing dams and associated appurtenances in a sustainable manner, and to strengthen the dam safety institutional setup of participating States / Implementing Agencies. Thus, statement 2 is correct.

Question 4
Consider the following statements regarding exomoon.
  1. It is a natural satellite that orbits an exoplanet or other non-stellar extrasolar body.
  2. The exomoons are larger than their companion planet and so their transit signal is strong.
Which of the statements given above are correct.
A
1 only
B
2 only
C
Both 1 and 2
D
Neither 1 nor 2
Current affairs Questions answers

Question 4 Explanation: 
An exomoon or extrasolar moon is a natural satellite that orbits an exoplanet or other non-stellar extrasolar body.The exomoons are difficult to find because they are smaller than their companion planet and so their transit signal is weak.

Recently, astronomers using Hubble and Kepler space telescopes have found compelling evidence for the existence of the first known moon outside our solar system. It has been orbiting a Jupiter-like planet Kepler-1625b, which lies about 8,000 light-years from Earth.

Question 5

A
Muslim League's boycott of the Constituent Assembly
B
