Answer 1

The question that would best be answered by an experiment is:

A. Does reducing screen exposure two hours before bedtime decrease the time it takes to fall asleep?

This question lends itself to experimentation because it involves manipulating a variable (screen exposure) to observe its effect on a specific outcome (time taken to fall asleep). An experimental approach would allow researchers to control conditions and establish a cause-and-effect relationship.
