Ascientist is observing elephants in asia. he notices that a specific species of moth lands on the faces of the elephants. on closer observation, he sees that the moths irritate the eyes of the elephants and then drink the tears that emerge. what scientific question could the scientist ask to explain this? a. do other species of moths also drink elephant tears? b. what nutrients that moths need are in elephant tears? c. how can the moths be kept off the elephants' faces? d. all of these

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
