1) - The opinion that one's own experiences are unique compared to others is due to perspective, however, the reason for one's experiences to in face be similar to other's would most likely be caused socially.
2) - I would definitely answer "d) social structure".
3) - Answers d and b are both likely candidates for being the answer, however, the answer choice d seems a bit opinionated which leads me to believe the answer is b.
4) - Answers a and b are both reasonable answers, I would most likely select a.
5) - The answer appears to be b.
6) - The answer "c) To distinguish between right and wrong" is the least fitting, therefore, the best answer as empirical research isn't likely to debate morals.
I hope this helps, Jasmeen! :)
