I'm not happy to do your homework but, hopefully, you'll learn from it. Here are the corrections:
The answer to 5 is D. ("Voyage" is a very long sea journey.)
The answer to 9 is D.
The answer to 11 is A.
The answer to 12 is B.
The answer to 15 is B.
The answer to 16 is most likely C. "Check-up"
could be used, but it's more often used when referring to a person or animal.
Now please tell my why these answers are correct.
