A weather balloon contains 59.5 L helum at sea level, where the atmospheric pressurels 101.3 kPa. Meteorologists want the balloon to eat at an altitude of
35,000 m where the pressure is 0.575 kPa. What volume will the balloon have at that altitude?

it should be all of them because it asks if you included all of those in your answer

explanation:

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.
