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.
Gear up and Make the Best Use of this initiative.
Do remember that, “the difference between Ordinary and EXTRA-Ordinary is PRACTICE!!”

Question 1 of 5
1. Question
Consider the following statements with respect to ‘Metal-Organic Frameworks (MOFs)’
- It is a class of porous, crystalline materials with a broad range of applications
- They derive their ability from the presence of nanopores, diminishing their surface areas
- These crystalline materials possess the remarkable ability to act as filters for crude oil purification
How many of the statement(s) given above are correct
Correct
Solution (b)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Correct Incorrect Correct MOFs are a class of porous, crystalline materials with a broad range of applications. They are composed of metal ions or clusters, which act as the joints, bound by multidirectional organic ligands, which act as linkers in the network structure. MOFs derive their ability from the presence of nanopores, enhancing their surface areas that, in turn, make them adept at absorbing and storing gases. These crystalline materials possess the remarkable ability to absorb gases, such as carbon dioxide, and store them as well as act as filters for crude oil purification. Context – Researchers have carried out an in-depth analysis of the mechanisms underlying the flexibility of crystals of Metal-Organic frameworks (MOFs)

Question 2 of 5
2. Question
With respect to ‘Rudram-1 Missile’, consider the following statements
Statement 1 – It is India’s first indigenous radiation missile developed by the Defence Research and Development Organisation (DRDO).
Statement 2 – The missile can be launched from varying altitudes, ranging from 500 meters to 15 kilometers
Which one of the following is correct in respect of the above statements?
Correct
Solution (d)
Statement Analysis:
Statement 1 Statement 2 Incorrect Correct Rudram-1 Missile is an air–to–surface missile developed by the Defence Research and Development Organisation (DRDO). It is India’s first indigenous anti-radiation missile. It features Inertial Navigation Systems (INS)-GPS navigation and a Passive Homing Head for the final attack, allowing it to accurately hit radiation-emitting targets. The missile can be launched from varying altitudes, ranging from 500 meters to 15 kilometers and has a range of up to 250 kilometers depending on the launch conditions. Context – India has successfully test-fired its first indigenous anti-radiation missile, the Rudram-1

Question 3 of 5
3. Question
Consider the following statements about ‘Indian Gaur’
- Gaurs primarily inhabitate evergreen and semi-evergreen forests along with moist deciduous forests
- Sexual dimorphism is prominent with only the male gaurs possessing horns
- It is classified as threatened under the IUCN Red list
How many of the statement(s) given above are correct
Correct
Solution (a)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Correct Incorrect Incorrect The Indian Bison of Gaur is the largest and tallest in the family of wild cattle. Gaurs are primarily the denizens of evergreen and semi-evergreen forests along with moist deciduous forests with open grasslands. Both males and females possess horns. The horns are pale green or yellowish brown in color and are not pointed upward but possess a slightly inward curvature. IUCN Red List: Vulnerable Wild Life Protection Act, 1972: Schedule I It is listed in CITES Appendix I. Context – The locally extinct Indian gaur has been spotted in the Nagarjunasagar Srisailam Tiger Reserve (NSTR) in Andhra Pradesh
