If you were trying to assess an individual's grasp of basic finance, which two questions would you ask them?

I’m trying to develop a quick survey for a group of entrepreneurs to gauge their knowledge in different areas. What questions would you ask someone to determine whether they understand key finance concepts important for starting a new business?

For example: What does Gross Margin mean?

or… What is the difference between Revenue and Earnings?

I’m looking for maybe ten questions or so…
