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 with respect to ‘Vikas Engine’
- It is a liquid fuelled rocket engine used in PSLV, GSLV Mark I and II and also in GSLV Mark III
- The engine uses Unsymmetrical dimethylhydrazine (UDMH) as oxidizer and Nitrogen tetroxide (N2O4) as fuel
Choose the correct statement(s)
Correct
Solution(a)
Statement Analysis:
Statement 1 Statement 2 Correct Incorrect Vikas engine is used to power the second stage of PSLV, boosters and second stage of GSLV Mark I and II and also the core stage of GSLV Mark III. The propellant loading for Vikas engine in PSLV, GSLV Mark I and II is 40 tons, while in GSLV Mark III is 55 tons. The engine uses up about 40 metric tons of Unsymmetrical dimethylhydrazine (UDMH) as fuel and Nitrogen tetroxide (N2O4) as oxidizer with a maximum thrust of 725 kN. Context – The Indian Space & Research Organisation (Isro) successfully test-fired the Vikas engine that will power the ambitious Gaganyaan mission into space.

- It is listed in the IUCN Red Data Book as a threatened species
Choose the correct statement(s)
Correct
Solution(d)
Statement Analysis:

Question 4 of 5
4. Question
‘SAMARTH’, a scheme recently seen in news is related to
Correct
Solution(d)
SAMARTH stands for Sustainable Agrarian Mission on use of Agro Residue in Thermal Power Plants. It is emerging that the efforts of the Government in transforming the problem of stubble burning into a solution of power production with lower carbon footprints, would continue to bear fruit with the active participation of Farmers, Pellet manufacturers and power plants in the country. This would yield additional income for farmers. It is going to play a big role towards clean energy transition of the country.
Context – The mission was launched recently

Question 5 of 5
5. Question
Consider the following statements regarding ‘mRNA vaccines’
- These vaccines are non-infectious.
- They provide cellular immunity as well as humoral immunity.
- They are stable over a vast range of temperature.
- The vaccine can be administered both by ex-vivo and in-vivo methods
Choose the correct statements
Correct
Solution(c)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Statement 4 Correct Correct Incorrect Correct mRNA vaccines are not constructed from an active pathogen (or even an inactivated pathogen), they are non-infectious. In contrast, traditional vaccines require the production of pathogens, which, if done at high volumes, could increase the risks of localized outbreaks of the virus at the production facility Biological advantage of mRNA vaccines is that since the antigens are produced inside the cell, they stimulate cellular immunity, as well as humoral immunity. Humoral immunity protects the body against extracellular pathogens and their toxins. Cell-mediated immunity protects the body against intracellular pathogens. mRNA is fragile, some vaccines must be kept at very low temperatures to avoid degrading and thus giving little effective immunity to the recipient. The vaccine can be administered by ex-vivo as well as in-vivo methods. The simplest way that ex vivo dendritic cells take up mRNA molecules is through endocytosis, a fairly inefficient pathway in the laboratory setting that can be significantly improved through electroporation. Context – mRNA vaccines were in news.
