Tim wanted to know what _______ to his backpack.a)have happenedb)happe...
Answer:
The correct answer is option C, "had happened."
Explanation:
In this sentence, the word "wanted" indicates that the action of wanting to know what happened to Tim's backpack occurred in the past. Therefore, we need to use a past tense form of the verb "happen" to match the tense of the sentence.
- Simple Past Tense (Option B): "Tim wanted to know what happened to his backpack." This option is incorrect because it does not convey the idea that the action happened before the time of wanting to know. It simply states that Tim wanted to know what happened, without any specific time reference.
- Present Perfect Tense (Option D): "Tim wanted to know what happens to his backpack." This option is incorrect because the present perfect tense is used to talk about actions or events that started in the past and continue to the present. However, in this sentence, Tim's desire to know what happened to his backpack is a one-time past event.
- Past Perfect Tense (Option C): "Tim wanted to know what had happened to his backpack." This option is correct because the past perfect tense is used to talk about an action that happened before another action in the past. In this case, the action of wanting to know what happened to the backpack (Tim's desire) happened after the action of the backpack being lost or something happening to it. Therefore, the past perfect tense is appropriate to show the sequence of events.
- Present Perfect Tense (Option A): "Tim wanted to know what have happened to his backpack." This option is incorrect because it uses the present perfect tense incorrectly. The present perfect tense is used to talk about actions or events that started in the past and continue to the present. Additionally, the use of the word "have" is incorrect because it does not agree with the past tense verb "wanted."
Therefore, option C, "had happened," is the correct answer as it accurately represents the sequence of events in the past.
