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 Rove Beetles, which one of the following statements is correct?
Correct
Solution (b)
Explanation:
Option (b) is correct. Rove beetles belong to the family Staphylinidae, one of the largest families of beetles. Their distinctive feature is the presence of shortened wing covers or elytra, which leave several flexible abdominal segments exposed. Option (a) is incorrect because they are insects belonging to the order Coleoptera, not arachnids. Option (c) is incorrect as rove beetles occur in diverse habitats, including leaf litter, decaying vegetation and moist terrestrial environments. Option (d) is incorrect because their scorpion-like posture is a defensive behaviour and does not indicate the presence of a true venomous sting.
Why this question?
Tests taxonomy and morphological features while using behavioural appearance as a trap.
Why important for UPSC?
Species in news are frequently tested through taxonomy, habitat and distinctive characteristics.

Question 2 of 5
2. Question
Larak Island, recently in news, is best described as:
Correct
Solution (b)
Explanation:
Option (b) is correct. Larak Island is a small Iranian island located near the strategically important Strait of Hormuz and is administratively associated with Iran’s Hormozgan Province. Its significance arises from proximity to one of the world’s most important maritime chokepoints. The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman, leading further towards the Arabian Sea. Options (a), (c) and (d) incorrectly associate Larak Island with other Gulf or Red Sea states and locations. For map-based elimination, remember that Larak lies in the Iranian maritime geography surrounding the Strait of Hormuz.
Why this question?
Tests strategic geography through precise association of islands and maritime chokepoints.
Why important for UPSC?
West Asian geography and energy-security chokepoints frequently appear in current affairs.

Question 3 of 5
3. Question
Consider the following statements regarding Hanging Glaciers:
They are ice masses perched on steep mountain slopes or valley walls.
They commonly terminate abruptly above steep slopes.
Their instability can trigger ice avalanches and cascading downstream hazards.
They are identical to glacial lakes formed behind moraine dams.
Which of the statements given above are correct?Correct
Solution (a)
Explanation:
Statements 1, 2 and 3 are correct. Hanging glaciers are ice masses located on steep mountain slopes or valley walls, often remaining at higher elevations after major valley glaciers retreat. Unlike valley glaciers, they may terminate abruptly above steep slopes and are vulnerable to ice break-offs, icefalls and avalanches. Such failures can produce cascading hazards, including ice-rock avalanches, debris flows, river blockages, flash floods and potentially GLOFs. Statement 4 is incorrect because a hanging glacier is an ice mass, whereas a glacial lake is a water body associated with glaciers or glacial landforms. Recent research identified numerous hanging glaciers in the Alaknanda basin.
Why this question?
Tests distinction between closely related Himalayan glacial landforms and cascading hazards.
Why important for UPSC?
Climate change and Himalayan disaster risks remain major geography-environment intersections.

Question 4 of 5
4. Question
Consider the following statements regarding the PM-SETU Scheme:
PM-SETU stands for Pradhan Mantri Skilling and Employability Transformation through Upgraded ITIs.
It is a Centrally Sponsored Scheme aimed at upgrading Government Industrial Training Institutes.
It proposes a Hub-and-Spoke model among selected ITIs.
It is exclusively designed for universities and higher education institutions.
Which of the statements given above are correct?Correct
Solution (a)
Explanation:
Statements 1, 2 and 3 are correct. PM-SETU stands for Pradhan Mantri Skilling and Employability Transformation through Upgraded ITIs. It is a Centrally Sponsored Scheme aimed at upgrading Government Industrial Training Institutes into modern and industry-aligned centres of excellence. The scheme proposes a Hub-and-Spoke approach, under which selected ITIs function as hub institutions supporting nearby ITIs. It emphasizes modern infrastructure, industry-linked courses, apprenticeships and skills relevant to emerging sectors such as AI, automation and green technologies. Statement 4 is incorrect because the scheme specifically focuses on vocational education and Government ITIs rather than universities.
Why this question?
Tests expansion, institutional target and implementation model through closely related statements.
Why important for UPSC?
Skilling and demographic dividend policies are increasingly important governance themes.

Question 5 of 5
5. Question
With reference to Magnetars, consider the following statements:
A magnetar is a type of neutron star with an exceptionally powerful magnetic field.
Neutron stars may form following the core-collapse supernova of massive stars.
Magnetars can emit intense X-rays and gamma rays due to magnetic-field decay and reconfiguration.
Vacuum birefringence refers to gravitational bending of light near a black hole.
Which of the statements given above are correct?Correct
Solution (a)
Explanation:
Statements 1, 2 and 3 are correct. A magnetar is a type of neutron star possessing an extraordinarily strong magnetic field. Neutron stars generally form after the core-collapse supernova explosions of massive stars. Magnetars produce intense X-ray and gamma-ray emissions, largely powered by the decay and reconfiguration of their powerful magnetic fields. Statement 4 is incorrect because vacuum birefringence is a quantum electrodynamic phenomenon in which extremely strong magnetic fields affect the polarisation and propagation of light through the quantum vacuum. It should not be confused with gravitational lensing or the bending of light caused by massive objects.
Why this question?
Tests distinction between quantum vacuum effects, gravity and extreme stellar objects.
Why important for UPSC?
Science questions increasingly connect current discoveries with fundamental physics concepts.
