The interviewers are curious about how varied your choice of schools is. Transparency and sincerity are of value here, yet it is wise to filter what you volunteer in how Midwestern ranks among the others you've applied to. Avoid saying anything offensive, such as, 'this school is my last choice.' Your best approach is to focus on their mission and value statements and those bits of branding they used to define and distinguish themselves from their competition. These points serve as a mark of pride for them, and the suggestion that you value and identify with them can go a long way in conveying you are a good match.
