"before"
Explanation:
because it told us the pre means before you can substitute the "pre-" in prehistorie to figure out the meaning.
The phrase that is infinitive is given in option (a): to go to the store. Therefore, "to" is the first word, "go" is the verb, and ends with the place "store."
<h3>What are infinitive phrases?</h3>
A combination of words known as an infinitive phrase includes an infinitive, a modifier, pronouns, direct objects, indirect objects, or complements of the action or state described in the infinitive.
Find the word to first, then look for the infinitive phrase. Second, it is an infinitive if the word immediately after to is a verb. Third, the infinitive phrase starts at to and finishes at the end of the sentence if it occurs in the midst of the sentence.
Alternative example:
Dawn assisted her friend in making a cake for his mother.
('Helped' is the "special" verb.) Her companion is the direct object. The bare infinitive of the infinitive phrase is "bake." A cake is its direct object. This time, the infinitive sentence also has an indirect object ("his mother").
Hence, option (a) contains infinitive.
