SOURCE
Which of the following is not a use of nuclear energy?
A) Therapy
B) Tracers
C) Hydrogen Production
D) None of the above
Solution & Detailed Explanation
Answer: (D) None of the above
Detailed Explanation
- Radioactive tracers are used to visualize organs and detect abnormalities.
- Radiation therapy is used to target and destroy cancer cells.
- Electrolysis is a promising option for carbon-free hydrogen production from renewable and nuclear resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyser.
Question 4
Economy | Banking | Easy | Live Mint
SOURCE
Consider the following:
- Higher the Variable Rate Reverse Repo (VRRR), less the supply of money in the market.
- Less supply of money in the market means a high rate of interests for loans.
Which of the statements above is or are correct?
A) 1 only
B) 2 only
C) Both 1 and 2
D) None of the above
Solution & Detailed Explanation
Answer: (C) Both 1 and 2
Detailed Explanation
- In VRRR, banks deposit surplus funds with RBI through auctions. The interest rate is again determined by competitive bidding, usually close to or above the reverse repo rate. RBI also uses the Variable Rate Reverse Repo (VRRR) to absorb excess liquidity from the banking system.
- Less supply of money in the market will lead to higher rates of interests for taking up loans. Loans will be expensive to take.

Consider the following:
1. The B-2s are service intensive.
2. The B-2s can be easily detected but not attacked due to their high speeds.
Which of the statements above is or are correct?
A) 1 only
B) 2 only
C) Both 1 and 2
D) None of the above
Solution & Detailed Explanation
Answer: (A) 1 only
Detailed Explanation
- The B-2s are extremely maintenance intensive. According to a detailed account in The Atlantic on the B-2s employed in Libya in 2018, 100 hours of maintenance were required for every hour of flight. This is mainly because the advantage of stealth is B-2’s edge, and it is achieved by design and radar-absorbing materials. To maintain them, the aircraft needs temperature controlled hangers to protect against changes in temperature, humidity, and dust.
- The B-2 has always inspired awe with its bat-like shape. It is a dual capable multi-role heavy bomber, powered by four engines. The B-2’s low observability is derived from a combination of reduced infrared, acoustic, electromagnetic, visual and radar signatures. These signatures make it difficult for sophisticated defensive systems to detect, track and engage the B-2.
