Answer 1

D) We met after school to study for the big math test next week.

Step-by-step explanation:

It uses an infinitive as an adverb. The infinitive "to study" explains why we met. Since adverbs can answer the question why, "to study" is functioning as an adverb.

Answer 2

The best answer for this question would be:

D) We met after school to study for the big math test next week.

Infinitive adverbs are verbs that are combined with the “to” in every sentence. It explains what happens on “why” the subject had done that action. In this case, the sentence decribes the idea of why they need to study.
