I suppose given is the verb in which case it is the past tense.
The correct answer is after.
Prepositions usually point to a location (in, on, under), but can sometimes refer to time as well, as in the sentence above. The word after can be used either as a preposition (which is the case here), or as an adverb. The difference is that prepositions are used with nouns, whereas adverbs are used with verbs or clauses.
Answer:
A restrictive clause contains a subject and a verb (2), is not set apart by punctuation (3), and is essential to the meaning of the sentence (4).
Explanation:
A restrictive clause is a clause which functions as a adjective to identify the word which it modifies. Since it is essential to the meaning of the sentence, it is not offset with commas. An example of a restrictive clause is, "The girl who ripped her dress is crying." A restrictive clause is opposite of a non-restrictive clause, which would include non-necessary information within commas. An examle of a non-restrictive clause is, "Sara, the girl who ripped her dress, is crying."
