1. This sentence is still very appropriate. Here "together" is an extension, which means that "Confucius" and "Mencius" are always mentioned together, just like two people (not books) who are closely related.

2. incisively and vividly is a neutral word that modifies "exposure", that's right.

There are some troubles in this. The answer is that "things that backfire" means "doing well", but losing the game is not necessarily a cause and effect.

This is a matter of habit. Time seems "completely different", don't you think?

5. I'm not sure

6. The obvious mistake of "posing" means that it is difficult to solve the problem without getting to the point. Isn't "posing" invalid? What are you criticizing?

7. I can't find it anywhere. If it is "all kinds of gems" and "everywhere" ~ ~ ~ Oh, my God!

It seems that you are right about this matter.

9. "Make a comeback" refers to politics, not "get up after failure" in the general sense, but return to your old job after losing your official position.

10. Congratulations, you are right again.
