Two states of matter are described below. state x: particles are ions that are far apart state y: particles are molecules that are far apart which combination of the state and a substance in that state is correct?

State X: Particles are ions that are far apart

So it is a plasma. The most common plasma state is lightning.

State Y: Particles are molecules that are far apart

So it is a gas. The most common gas is air.

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.
