This question is less about what you answer than how you answer. Your answer could serve to reveal whether you've put in the time to research their website and university thoroughly. Asking questions that you could have learned on your own will suggest you have poor study habits. Asking too much about the culture, social life, and extra-curricular activities may cause you to appear unfocused and more interested in the nightlife than your career and what your university has to offer. Asking no questions won't suggest you are informed but that you don't ask questions and aren't self-guided in your work.

So keep most of your questions academically related, perform your research, and ask compelling questions that delve more deeply into what you've learned. Having a few thoughtful questions prepared shows the panel you are keenly interested in the experiences Temple University School of Dentistry will offer you as a student and future alumnus/alumnae.
