stupid i wont let you get a chance

explanation:

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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.
