Calculate the concentration of hydrochloric acid if 50.0 mL of hydrochloric acid is neutralized by 25.0 mL of 2.0 M sodium hydroxide. The neutralization reaction is shown below HCl + NaOH > H2O + NaCl

i would say b

explanation:

but i think i would need more information than that

where are the choice options?

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.
