Factoids for Prelims 2021
Hi,
Ranyo Ashoka, Himalayan nettle, Denisovan - Who would have thought of such random questions?
Creating this thread with the sole purpose of sharing facts that can be relevant for Prelims. While there is always this thought, that there is no end to learning and mugging up facts, but if we observe closely - the options are not very close and elimination is easy. By pooling our resources here, if we give it one reading also, the probability of retaining it on the D day and eliminating options increases exponentially.
I request the aspirants to actively contribute here and let's hope that we strike gold on 31st ;).
With reference to Interest Rate Growth Differential (IRGD), choose the correct statement(s):1. Interest Rate Growth Differential (IRGD) is the difference between the interest paid on government debt and growth rate of economy2. In Indian context, it is negative mainly due to lower interest ratesA. 1 onlyB. 2 onlyC. Both 1 and 2D. Neither 1 nor 2
A?
Should be negative due to higher growth rates.

Akbar_Birbal,
Archand,HornbillQuantum Tunneling:
1. particles penetrate a potential energy barrier with a height which is greater than the total energy of the particles.
2. Why important? because it violates the principles of classical mechanics. According to classical mechanics, if particle has total energy less than the height of the barrier, they cannot penetrate it. But in quantum tunneling this fails.
3. Where it happens in nature? Sun-nuclear fusion is possible because of quantum tunneling.
If question comes, it would relate to if this happens in nature or not (3rd statement) or if it violates laws of classical mechanics (2nd statement).

@UK01 Shankar open mock?
Yes I attempted.. it's quite doable and questions of Environment,agri and science are good one depending on PYQs of UPSC pattern. History and polity not that much in paper.

There's a difference between resources and reserves.
- Mineral resources that are potentially valuable, and for which reasonable prospects exist for eventual economic extraction.
- Mineral reserves or Ore reserves are valuable and legally, economically, and technically feasible to extract
Bolivia has highest Lithium resources. Chile has highest reserves
Also, Australia has highest Uranium reserves. Kazakhstan tops in Uranium production
