It is a broad question and it may help to look at it in the context of the other questions that Ivey asks. The first question, What are your professional goals and how will an Ivey MBA help you achieve these goals? asks you to focus on your career; you'll want to give a brief description of your past experience for context, then discuss your goals and how Ivey will help.

The second question, During your 12 months in the Program, what impact do you hope to have on your classmates and on their Ivey experience? is really trying to get at your personal skills and activities. It's asking what you will contribute to campus.

So with your experience, goals and extracurriculars taken care of, this third question is a more open-ended one for you to get to describe your personality, what you're curious about and what makes you tick. Both the choice of the country (where) and why are critical. Maybe you want to go to an unexplored part of the world because you love adventure and discovering how people who live in remote (to us) areas solve problems without access to the technology we have. Or maybe you love experiementing in the kitchen and want to be a field reporter in a place where you can observe in the field innovative cooking methods and flavors. Maybe you are an art buff and want to be a field reporter in Paris, observing how school children are exposed to great works of art.

Basically, it's a completely open-ended question that encourages you to think about parts of your personality and interests that don't fit into the other questions.

Best of luck.
