Record any similarities and differences between your predicted graph and the graph of actual data

There is no graphs attached hence I will provide a rundown of possible discussion points.

Differences/ similarities in trendline data, increase/ decrease/no change in trendline for a certain range of data on the x axis and the degree of change observed (how much increase/ decrease).

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.
