This depends on the version of PowerPoint, but in 2002 and above, you can
use animation triggers to press a button and either trigger a shape to
come in or trigger a shape (that is covering the answer) to leave. This
page should help you get started:

Also, you can search the Web and find several Family Feud games in
PowerPoint as examples.

By the way, if you are using 2000 or 97, you will need to use VBA to
accomplish this.

If you have XP or 2003 then you should use trigger animations. Here are a
couple of articles to get you going! Trigger animations wont work in 2000 and
earlier
