Answer:
“when I asked you to help me move”
Step-by-step explanation:
Adjective clauses are those that modify, describe or give more information about nouns. We can identify them because they are usually placed right next the noun they describe, and beginning with a relative pronoun (namely, who, whom, whose, that or which) or a relative adverb (when, where or why). In the question, the adjective clause is “when I asked you to help me move” because it gives us information or more detail about the noun “time,” and it also begins with the relative adverb “when.”
