Answer 1

14. The only one that makes sense is "must" (if you must go...); the other three indicate permission or potential, but "must" indicates "have to"!

17. The choice is "had" -- sequence of tenses in an "if...then..." type of sentence (even though the word "then" isn't written). As before, the other words do not make sense; they are all some form of present or future, but the correct one is past tense.
