Explanation:

The density of a substance can be found by using the formula

volume = final volume of water - initial volume of water

volume = 13.91 - 12 = 1.91 mL

We have

We have the final answer as

Hope this helps you

i wish i could but this one is weird give me abc and i can solve it.

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.
