Question 1 of 5
1. Question
Q1. The principal scientific objective of the Euclid Space Telescope is to:
Correct
Q.1) Solution (b)
Explanation
The Euclid Space Telescope, launched by the European Space Agency (ESA) with contributions from NASA, aims to construct the largest three-dimensional map of the Universe to investigate dark matter, dark energy and the evolution of cosmic structures. Operating from the Sun–Earth L2 Lagrange Point, it surveys nearly one-third of the sky using visible and near-infrared instruments. Although Euclid’s observations may contribute to exoplanet discoveries through gravitational microlensing, this is not its primary mission. Options (a), (c) and (d) describe objectives of other missions or only partial scientific applications. UPSC frequently tests the distinction between different space observatories and their scientific goals.
Why this question? Separates cosmology missions from planetary exploration missions.
Why important for UPSC? Lagrange-point missions have become a recurring prelims topic.
PYQ Pattern Link: Similar to UPSC questions on Aditya-L1, James Webb and AstroSat.

Question 2 of 5
2. Question
Q2. With reference to Lonar Lake, consider the following statements:
- It is the world’s only known meteorite impact crater lake formed in basaltic rock.
- It is an endorheic lake having saline and alkaline water.
- It was designated a Ramsar Site before being recognised as a National Geo-heritage Monument.
- It was formed due to volcanic collapse associated with the Deccan Traps.
Which of the statements given above are correct?
Correct
Q.2) Solution (a)
Explanation
Statements 1, 2 and 3 are correct. Lonar Lake, located in Maharashtra’s Buldhana district, is the world’s only known meteorite impact crater lake in basaltic rock, formed in the Deccan Trap basalt around 50,000 years ago. It is an endorheic, saline and alkaline lake with no natural outlet. It was declared a Ramsar Site in 2020 and is recognised as a National Geo-heritage Monument by the Geological Survey of India. Statement 4 is incorrect because the crater was formed by meteorite impact, not volcanic collapse. UPSC frequently confuses volcanic craters with meteorite impact craters to test conceptual understanding.
Why this question? Tests geomorphology by contrasting impact and volcanic landforms.
Why important for UPSC? Ramsar Sites and unique geomorphic features are favourite prelims areas.
PYQ Pattern Link: Similar to UPSC questions on Ramsar wetlands and impact craters.

Question 3 of 5
3. Question
Q3. Which one of the following features contributes most significantly to the strategic importance of Seychelles for India?
Correct
- Q.3) Solution (b)
Explanation
Seychelles is strategically important because it is located in the Western Indian Ocean, close to major Sea Lines of Communication (SLOCs) connecting Asia, Africa and Europe. This makes it a key partner for India in maritime security, anti-piracy operations, the Blue Economy and regional initiatives such as SAGAR and MAHASAGAR. It is an archipelagic nation comprising 115 islands with a vast Exclusive Economic Zone (EEZ). Options (a), (c) and (d) incorrectly associate Seychelles with other strategic maritime chokepoints that are geographically distant. UPSC frequently tests map-based strategic geography by linking countries with nearby maritime routes rather than famous straits.
Why this question? Tests Indian Ocean strategic geography instead of mere factual recall.
Why important for UPSC? Maritime security and island nations are increasingly important in prelims.
PYQ Pattern Link: Similar to UPSC map-based questions on Mauritius, Maldives and IORA.

Question 4 of 5
4. Question
Q4. With reference to Brachybacterium netajii, consider the following statements:
- It belongs to the phylum Actinobacteria.
- It was isolated from the Hooghly River and exhibits the ability to degrade p-Nitrophenol (PNP).
- It is a halophilic bacterium that survives only in marine environments with salinity exceeding 20%.
- It possesses genes encoding ectoine, a stress-protective compound with biotechnological applications.
Which of the statements given above are correct?
Correct
Q.4) Solution (a)
Explanation
Statements 1, 2 and 4 are correct. Brachybacterium netajii is a newly discovered bacterial species belonging to the phylum Actinobacteria. It was isolated from the Hooghly River, a distributary of the Ganga, and has demonstrated the ability to degrade p-Nitrophenol (PNP), a toxic industrial pollutant. It also tolerates heavy metals such as arsenic, cadmium, lead and mercury and contains genes encoding ectoine, a stress-protective molecule with industrial significance. Statement 3 is incorrect because the bacterium is halotolerant, meaning it can tolerate saline conditions (up to about 9% salt), but it is not an obligate halophile requiring highly saline marine environments. UPSC frequently tests the distinction between halotolerant and halophilic organisms.
Why this question? Tests microbiological terminology instead of factual memorisation.
Why important for UPSC? Bioremediation and environmental biotechnology are emerging prelims themes.
PYQ Pattern Link: Similar to UPSC questions on biofertilisers, extremophiles and microbial applications.

Question 5 of 5
5. Question
Q5. With reference to the PM–RAHAT Scheme, consider the following statements:
- It is implemented by the Ministry of Road Transport and Highways under Section 162 of the Motor Vehicles Act, 1988.
- The scheme provides cashless treatment up to ₹1.5 lakh for eligible road accident victims.
- Emergency treatment is available only during the Golden Hour immediately after the accident.
- Payments under the scheme are made through the Motor Vehicle Accident Fund (MVAF).
Which of the statements given above are correct?
Correct
- Q.5) Solution (a)
Explanation
Statements 1, 2 and 4 are correct. The PM–RAHAT (Prime Minister – Road Accident Victims’ Hospitalisation and Assured Treatment) Scheme is administered by the Ministry of Road Transport and Highways (MoRTH) under Section 162 of the Motor Vehicles Act, 1988. It provides cashless treatment up to ₹1.5 lakh for eligible road accident victims, with coverage extending up to seven days from the date of the accident. Payments are routed through the Motor Vehicle Accident Fund (MVAF) and integrated with the eDAR and TMS 2.0 digital platforms. Statement 3 is incorrect because the scheme is not restricted to the Golden Hour; treatment support extends beyond the initial emergency period, subject to scheme provisions. UPSC often inserts the Golden Hour concept to confuse candidates.
Why this question? Tests statutory basis alongside scheme implementation.
Why important for UPSC? Road safety, social welfare and digital governance are growing focus areas.
PYQ Pattern Link: Similar to UPSC questions on Ayushman Bharat, eDAR and Motor Vehicles Act.
