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
-
Consider the following statements:
Assertion (A):
Monetary tightening by the central bank may fail to curb headline inflation in the short term.Reason (R):
Headline inflation is significantly influenced by supply-side shocks, which are less responsive to changes in interest rates.Which one of the following is correct in respect of the above statements?
Correct
-
Solution: a
Explanation:
Headline inflation includes all items, including volatile food and fuel prices, which are prone to supply-side shocks (e.g., droughts, global oil price spikes).
Monetary tightening (e.g., raising interest rates) works mainly through demand-side control — reducing credit and consumption. It has limited impact on supply-side inflation in the short run.
Thus, even if the central bank tightens policy, headline inflation may remain high due to external or weather-related shocks, and R correctly explains A. Hence Option A is correctIncorrect

2. Question
Consider the following statements regarding the Kailash Manasarovar Yatra:
-
It is jointly organized by the Governments of India and Nepal.
-
The Yatra provides access to pilgrimage sites located in the Tibet Autonomous Region of China.
-
The pilgrimage holds religious significance for Hindus, Buddhists, Jains, and Bon followers.
-
The Yatra was resumed in 2025 after a suspension due to the COVID-19 pandemic and border tensions.
How many of the above statements are correct?
Correct
-
Solution: c.
Explanation:
-
- Statement 1: The Yatra is jointly organized by India and China, not Nepal. Nepal is involved in an alternate route via the Humla region but not in the main government-organized Yatra. Hence statement is Incorrect
- Statement 2: The pilgrimage sites – Mount Kailash and Lake Manasarovar – are located in the Tibet Autonomous Region of China. Hence the statement is Correct
- Statement 3: The Yatra is significant for Hindus (abode of Lord Shiva), Buddhists (sacred to Buddha), Jains (site of Rishabhdev’s liberation), and Bon religion followers. Hence the statement is Correct
Statement 4: The Yatra resumed in 2025 after being suspended since 2020 due to the pandemic and border tensions. Hence the statement is Correct

Question 3 of 5
3. Question
-
Which of the following best explains why cryptocurrency exchanges are particularly vulnerable to cyberattacks?
-
Lack of centralized regulatory oversight and global standardization.
-
Use of hot wallets connected to the internet for liquidity management.
-
Transparency of blockchain transactions makes them easier to trace and reverse.
Select the correct answer using the code below:
Correct
-
Solution: d.
Explanation:
- Statement 1: Cryptocurrency exchanges often operate across jurisdictions with limited or inconsistent regulatory oversight, making enforcement and security standards fragmented. Hence statement is Correct
- Statement 2: Hot wallets are digital wallets connected to the internet and used for real-time transactions. They are more vulnerable to hacking attempts than cold (offline) wallets. Hence statement is Correct
Statement 3: While blockchain is transparent, transactions are not easily reversible, especially when routed through mixers like Tornado Cash. Transparency aids in tracking, but not reversal. Hence statement is Incorrect

Question 4 of 5
4. Question
-
Consider the following statements regarding tidal phenomena:
-
Spring tides occur only when the Moon is at its perigee and in conjunction or opposition with the Sun.
-
Neap tides are formed when the gravitational forces of the Sun and the Moon are orthogonal to each other.
-
Diurnal inequality in tides arises primarily due to the Moon’s declination.
Which of the above statements is/are correct?
Correct
-
Solution: d.
Explanation:
-
Statement 1: Spring tides occur during new moon and full moon phases, when the Sun, Earth, and Moon are aligned (syzygy). They can happen at both perigee and apogee, though they are stronger at perigee. So, the condition is not exclusive. Hence statement is Incorrect
-
Statement 2: Neap tides occur during the first and third quarter when the Sun and Moon are at right angles relative to Earth, partially cancelling each other’s gravitational pull. Hence statement is Correct
Statement 3: Diurnal inequality (difference in height between the two high tides in a day) is influenced by the Moon’s declination (the angle between the Moon’s orbital plane and Earth’s equator), affecting tidal bulge distribution. Hence statement is Correct
Incorrect
-

Question 5 of 5
5. Question
Allographa effusosoredica, recently in news is:
Correct
-
Solution: A
Explanation:
Allographa effusosoredica is a newly discovered lichen species found in the Western Ghats, one of the world’s richest biodiversity hotspots.Key Features:
- Belongs to the genus Allographa; this is the 53rd species of this genus recorded in India.
- Notable for its:
- Crustose (crust-like) thallus
- Effuse soredia – powdery asexual structures for reproduction
- Presence of norstictic acid, a rare secondary metabolite in lichens
Scientific Significance:
- Discovered by MACS-Agharkar Research Institute, Pune
- Identified using an integrated approach:
- Classical taxonomy
- Chemical profiling
- Molecular sequencing (markers: mtSSU, LSU, RPB2 for fungus and ITS for alga)
- Closely related to Allographa xanthospora genetically, but morphologically resembles Graphis glaucescens
Ecological Importance:
- Lichens like this play roles in:
- Soil formation
- Supporting micro-ecosystems
- Acting as bioindicators of environmental change
Symbiotic Nature:
- A symbiosis between fungus and photobiont (Trentepohlia algae)
- Enhances understanding of ancient mutualisms in tropical ecosystems
