After observing a moth that is camouflaged against dark-colored bark, a scientist asks a question. The scientist discovers that the question has already been asked and answered by several investigations. What should the scientist do?
Answer
A
The scientist should test the question anyway.
B
The scientist should broaden the scope of the question.
C
The scientist should come up with a new way to test the question.
D
The scientist should revise the question to address a gap in knowledge.
Explanation
If several investigations have already answered the scientist’s question, repeating it in the same way is unlikely to add useful knowledge. The scientist should look for something those investigations did not address and revise the question to explore that gap. So the best choice is “revise the question to address a gap in knowledge.”
