Question

Which question is testable?

Answer 1

Answer:

A.) How does changing the amount of water affect the growth of corn?

Explanation:

A seems to be the most testable question since you can't reasonably test if using human tissue that was removed for surgery is ethical or not, being happy or unhappy with a new job doesn't require a test, and asking if people will or will not be disappointed with an increase in insurance rates should be enough, no test required.
