Which of these topics would be limited enough for a short paper?
Health and fitness
The benefits of mandatory health insurance

The benefits of mandatory health insurance

Explanation:

The benefits of mandatory health insurance are a more narrow topic that refers only to one thing that should be pointed out. Short papers still give you enough information but are generally much more straightforward.

As it is usually 3 to 5 pages long, the topic should be clear and narrow so that you could put every needed information on 3 pages.
