Answer 1

The best scientific question about insects that George could investigate with an experiment is:

A. Do different food types affect the growth rate of beetles?

This question is specific, measurable, and allows for experimentation by changing the food types and observing their effects on beetle growth. The other options are either subjective (C), not easily testable (B), or too broad for an experimental approach (D).
