Question

Which contraction correctly completes the sentence?  Wolves __________ always howl.   A. doesn't   B. don't

Answer 1

The answer is B. don't. When you're not sure, separate out the contraction(don't=do not), and check the subject-verb agreement. "Wolves" is plural, so I needs a verb of "do". Normally it is the one that will sound better.

Answer 2

The answer is B. Don't
