The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.

Question 1 of 5
1. Question
With reference to spectrum allocation in India, consider the following statements:
- Administrative allocation of spectrum is more suitable for satellite-based services than mobile telecom services.
- Auctioning of spectrum generally results in higher spectrum prices due to market competition.
- The Government of India has uniformly adopted the auction method for all types of spectrum allocation.
Which of the statements given above is/are correct?
Correct
Answer: A. 1 and 2 only
Explanation:
- Statement 1: Correct. Administrative allocation is preferred for satellite services (e.g., Starlink) due to global spectrum sharing and technical constraints of auctioning shared spectrum.
- Statement 2: Correct. Auctions are market-driven, often resulting in high costs due to competitive bidding among telecom operators.
- Statement 3: Incorrect. India uses both methods—auction for mobile services and administrative allocation for satellite communication and other strategic sectors.
Incorrect
Answer: A. 1 and 2 only
Explanation:
- Statement 1: Correct. Administrative allocation is preferred for satellite services (e.g., Starlink) due to global spectrum sharing and technical constraints of auctioning shared spectrum.
- Statement 2: Correct. Auctions are market-driven, often resulting in high costs due to competitive bidding among telecom operators.
- Statement 3: Incorrect. India uses both methods—auction for mobile services and administrative allocation for satellite communication and other strategic sectors.

Question 2 of 5
2. Question
With reference to artificial weather modification techniques, consider the following statements:
- Cloud seeding involves dispersing substances like silver iodide to induce precipitation.
- Marine cloud brightening is aimed at enhancing the Earth’s albedo by increasing the reflectivity of oceanic clouds.
- Stratospheric aerosol injection is a technique used to trap solar radiation within the lower atmosphere to increase rainfall.
- Weather modification techniques are universally accepted and regulated under the United Nations Framework Convention on Climate Change (UNFCCC).
Which of the statements given above is/are correct?
Correct
Answer: A. 1 and 2 only
Explanation:
- Statement 1: Correct. Cloud seeding is a widely known weather modification technique used to enhance rainfall using agents like silver iodide or salt.
- Statement 2: Correct. Marine cloud brightening involves spraying salt particles into clouds over oceans to increase their reflectivity (albedo), thus cooling the Earth.
- Statement 3: Incorrect. Stratospheric aerosol injection aims to reflect solar radiation back into space, not trap it or increase rainfall.
- Statement 4: Incorrect. There is no universal regulation of weather modification technologies under UNFCCC or other global treaties; governance remains fragmented and controversial.

Question 3 of 5
3. Question
With reference to MagIC Microscopy (Magnetic Isolation and Concentration cryo-electron microscopy), consider the following statements:
- It allows structural analysis of biological samples at much lower concentrations than traditional cryo-EM.
- The technique uses magnetic beads to concentrate target molecules from dilute solutions.
- MagIC eliminates the need for flash-freezing in cryo-electron microscopy.
- A computational workflow named DuSTER is used to filter background noise and improve image clarity.
Which of the statements given above is/are correct?
Correct
Answer:
- 1, 2 and 4 only
Explanation:
- Statement 1 is correct: MagIC enables analysis at concentrations 100 times lower than traditional methods.
- Statement 2 is correct: Magnetic beads help isolate and concentrate molecules.
- Statement 3 is incorrect: Flash-freezing remains essential in cryo-EM to preserve the sample structure.
- Statement 4 is correct: DuSTER workflow improves image quality by filtering noise.
