Answer:
#1 question, I THINK you already answered #1, but I would go with "between" also. #2 question, I would go for "since." #3 If you mean he's back, then it would be "for", but if you mean he's leaving, then I would go for "in." #4 I would go for "on." #5 Is either "by", or "at." #6 Is "to." #7 is "to" #8 If that's the full sentence, then I would go for "on"? #9 I would do "to." #10 You didn't put suggestions sooo... I would go for "to" anyway. #11 "at" #12 If that's a complete sentence, then I would do "for". #13 I would do "near", "above", or "at". #14 I would do "through". #15 I would do "on". #16 I would do "in". #17 I would "in". #18 I would do "under" #19 I would do "on", "near" or "by".
