Soil texture affects: A) The storage and movement of air and water through the soil
B) The way the soil is assembled
C) The amount of organic matter that is present in the soil

lol idk man i guess u gotta ask bill nye the science guy

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.
