Knowledge of types of clauses
Consider the answers
A. She will call you to confirm until she receives the parcel.
→ Does not match in meaning. At the same time, it is grammatically incorrect when “confirm” is a transitive verb, we always need an object to follow it, while here it is an adverbial clause of time, so it is easy to eliminate immediately.
B. Wrong answer is similar to answer A.
C. Grammatically and semantically correct: confirm sth: confirm something
D. Wrong answer A, B.
How to consider other answers:
– The verb of the given sentence part is in the future tense
→ Expressing an action that has not happened or will happen in the future, so in the latter part, it is not possible to conjugate verbs in the past tense, past continuous or past perfect.
→ Type A, B, D. → C is correct (mix present simple with simple future)
She will call you to confirm when she received the parcel.
