The correct answer is Ann Arbor because it is the location of the University of Michigan, which is one of the two major universities mentioned in the question. Michigan State University, on the other hand, is located in East Lansing, which is a separate city.

Bloomington, mentioned in another option, is the home of Indiana University, while Columbus is known for The Ohio State University. Thus, Ann Arbor, being the site of the University of Michigan, is the right answer in the context of the question asked.
