UPSC Previous Year Questions: CSP 2021

One cannot place less emphasis on the fact as to how important it is to solve questions asked by UPSC Previously. In fact, UPSC tends to repeat from its own stock, verbatim. 

This thread, shall be solely dedicated for posting questions asked in CSP & CAPF.

I shall be posting questions here on a daily basis. Urge you all to answer these in all seriousness. Shoot doubts if you have any, wrt solving any question. 

Remember the idea is to solve them, again. Reading questions and solutions is NOT sufficient. 

Cheers!

Gambusia fish.

Known as guppies. I have a small bowl in my study room. They are small, cost 20 rupees a pair and multiply like anything. They dont  need the pump and all unlike the gold fish which dies in the bowl.
