Answer 1

6. Good

("Well" is used more to described how someone is doing. "Best" and "better" are used to compare one thing to another, which is not being done in this sentence).

7. Always

(All of the other words are synonyms, and "always" makes the most sense logically).

8. It

(Since it is talking about the act of replying, "it" would be used. The other words would only be used if the sentence was talking about a person).

9. Out

(Giving in and giving up are synonyms, and "never give for any personal..." does not make sense).

10. Users

(not sure about this one, but I feel like it is the only word that makes sense in the context).
