Question 1 of 5
1. Question
Q1. Consider the following statements regarding E85 fuel and Flex-Fuel Vehicles (FFVs):
- E85 fuel contains 85% ethanol and 15% petrol.
- Flex-Fuel Vehicles can operate only on ethanol-dominant fuels such as E85 and E100.
- Ethanol’s corrosive nature is one of the challenges associated with large-scale adoption of E85 fuel.
Which of the statements given above are correct?
Correct
Q.1) Solution (a)
Explanation:
- Statement 1 is correct because E85 is a blend consisting of 85% ethanol and 15% petrol.
- Statement 2 is incorrect since Flex-Fuel Vehicles (FFVs) are designed to operate on varying ethanol-petrol blends such as E20, E85 and even E100 in some cases; they are not restricted only to ethanol-dominant fuels.
- Statement 3 is correct because ethanol has corrosive properties that may require engine modifications and specialized fuel-system components.
UPSC often frames questions around the technical limitations of alternative fuels rather than merely their advantages.
The topic also relates to India’s ethanol blending programme, energy security, reduced crude oil imports and cleaner mobility transitions.
Why this question?
Combines fuel chemistry with transport technology and policy.Why important for UPSC?
Biofuel transition is central to climate and energy governance.PYQ Pattern Link
Similar to UPSC questions on ethanol blending and alternative fuels.Incorrect

Question 2 of 5
2. Question
Q2. Daraxonrasib, recently seen in the news, is significant because:
Correct
Q.2) Solution (b)
Explanation:
Daraxonrasib (RMC-6236) is a targeted oral anti-cancer drug developed for KRAS-driven tumours, especially pancreatic ductal adenocarcinoma (PDAC).
It belongs to a new category called RAS(ON) multi-selective inhibitors and blocks abnormal RAS/KRAS signalling pathways responsible for uncontrolled cellular proliferation.
- Option (a) incorrectly associates it with gene-editing therapy.
- Option (c) confuses it with vaccine-based approaches.
- option (d) wrongly categorizes it as monoclonal antibody therapy.
UPSC increasingly asks conceptual biotechnology questions involving targeted therapy, precision medicine and genomics.
The significance of Daraxonrasib also lies in the fact that KRAS was historically considered an “undruggable” target.
Why this question?
Distinguishes targeted therapy from other biomedical technologies.Why important for UPSC?
Precision medicine and genomics are rapidly expanding fields.PYQ Pattern Link
Similar to UPSC biotechnology and cancer-therapy questions.Incorrect

Question 3 of 5
3. Question
Q3. Consider the following statements regarding Crotalaria phulei:
- It belongs to the Fabaceae family.
- Species of the genus Crotalaria are associated with nitrogen fixation and green manure use.
- The species was discovered in the alpine ecosystems of the Western Himalayas.
Which of the statements given above are correct?
Correct
Q.3) Solution (a)
Explanation:
- Statements 1 and 2 are correct. Crotalaria phulei belongs to the Fabaceae (Leguminosae) family, many members of which are known for nitrogen fixation due to symbiotic relationships with bacteria. Species of Crotalaria are often used for green manure and soil enrichment.
- Statement 3 is incorrect because the plant was discovered in the dry deciduous forests and grasslands of the Vidarbha region in Maharashtra, not the Western Himalayas.
UPSC frequently tests ecological concepts through newly discovered species, especially by linking taxonomy with habitat characteristics and ecological functions.
The question also examines understanding of leguminous plants and biodiversity documentation.
Why this question?
Uses habitat mismatch as the elimination trap.Why important for UPSC?
Species discovery and taxonomy remain recurring ecology themes.PYQ Pattern Link
Comparable to UPSC questions on endemic flora and fauna.Incorrect

Question 4 of 5
4. Question
Q4. Consider the following statements regarding the Valley of Flowers National Park:
- It is located in the Eastern Himalayas of Arunachal Pradesh.
- It forms part of the Nanda Devi Biosphere Reserve.
- Brahma Kamal and Blue Poppy are among the notable floral species found there.
Which of the statements given above are correct?
Correct
Q.4) Solution (d)
Explanation:
- Statement 1 is incorrect because the Valley of Flowers National Park is located in Chamoli district of Uttarakhand in the Western Himalayas, not the Eastern Himalayas.
- Statement 2 is correct since the park forms part of the Nanda Devi Biosphere Reserve and is recognized as a UNESCO World Heritage Site under the Nanda Devi and Valley of Flowers National Parks.
- Statement 3 is also correct because the park is famous for alpine floral diversity including Brahma Kamal, Blue Poppy, Primulas and Himalayan Bellflower.
UPSC frequently frames geography-environment questions by combining location-based traps with biodiversity details. The topic also links protected areas with high-altitude ecology and conservation management.
Why this question?
Location mismatch creates the central elimination trap.Why important for UPSC?
Protected areas and UNESCO sites are recurring prelims topics.PYQ Pattern Link
Similar to UPSC mapping questions on biosphere reserves and parks.Incorrect

Question 5 of 5
5. Question
Q5. With reference to the Pennar River, consider the following statements:
- It originates in the Nandi Hills of Karnataka.
- It is a perennial west-flowing river draining into the Arabian Sea.
- Its basin largely lies in the rain-shadow region associated with the Eastern Ghats.
Which of the statements given above is/are correct?
Correct
Q.5) Solution (a)
Explanation:
- Statement 1 is correct because the Pennar River originates in the Nandi Hills of Chikkaballapur district in Karnataka.
- Statement 2 is incorrect since Pennar is an east-flowing seasonal river draining into the Bay of Bengal near Nellore, not the Arabian Sea. It is also largely non-perennial.
- Statement 3 is correct because much of its basin lies in the rain-shadow region of the Eastern Ghats, contributing to the drought-prone nature of the Rayalaseema region.
UPSC often asks peninsular river questions through combinations of source, drainage direction, tributaries and physiographic regions. Such questions require conceptual map-based understanding rather than rote memorization.
Why this question?
Combines drainage pattern with climatic geography concepts.Why important for UPSC?
Peninsular river systems are a perennial UPSC favorite.PYQ Pattern Link
