This question is more nuanced than it seems. Your interviewers want to know whether you'd have emotional support or resistance from your family if accepted into Touro University. They're curious if you have financial support as well. But most importantly, they are curious whether pursuing a career in medicine is a career path you've chosen for yourself or if it was chosen for you by your family. Mention anyone in your family who may have followed a similar path in the medical field and whether you desired to follow in their footsteps.
