Answer 2

Ans.

A proper scientific question includes certain features. It should be answerable (have real answers), can be verified (means it can be tested by measurements  or experiments), and should lead to a falsifiable hypothesis (it should make an hypothesis that can be failed by others). The given question is a scientific question as it the speed of hummingbirds can be measured experimentally, it is answerable, and a hypothesis can be made on experimental results.

Hence, the correct answer is option, 'it can be tested during filed studies.'
