Past Perfect Tense - Practice (MCQ) - Mechanical Engineering MCQ

To determine the correct verb form to fill in the blank, let's analyze the sentence structure and the tense of the verb.
1. Sentence structure:
The sentence is in the past tense because the word "before" indicates that the action happened in the past. Since the sentence is in the past tense, we need to use a past participle form of the verb.
2. Tense of the verb:
The verb "see" is an irregular verb, and its past participle form is "seen." Therefore, we need to use the past participle form of the verb "see" in the sentence.
3. Options analysis:
- Option A: "seen" - This is the past participle form of the verb "see," but it is not the correct form because it lacks the auxiliary verb needed for past perfect tense.
- Option B: "had seen" - This is the correct answer. It uses the past perfect tense, which is formed by combining the auxiliary verb "had" with the past participle form of the verb "see."
- Option C: "have seen" - This is the present perfect tense, which is incorrect because the sentence is in the past tense.
- Option D: "has see" - This is incorrect because it uses the present tense instead of the past tense.
Therefore, the correct answer is option B: had seen.

Explanation:
The question is asking about the correct verb tense to use in relation to Tim's backpack.
To determine the correct answer, we need to consider the context and the meaning of the sentence.
The sentence is in the past tense because it uses the word "wanted," which indicates a past desire or intention.
Now let's analyze each option:
A: have happened
- This is in the present perfect tense, which is used to describe an action that started in the past and has a connection to the present. However, it doesn't fit the context of Tim wanting to know what happened to his backpack in the past.
B: happened
- This is in the simple past tense, which is used to describe a completed action in the past. It is the most appropriate tense to use in this context.
C: had happened
- This is in the past perfect tense, which is used to indicate an action that occurred before another action in the past. However, there is no indication of another past action in the sentence, so this tense is not necessary.
D: happens
- This is in the simple present tense, which is used to describe general truths, habits, or actions happening in the present. It does not match the past tense context of the sentence.
Therefore, the correct answer is B: happened.

To determine the correct verb form to fill in the blank, we need to consider the context and the tense used in the sentence.
Given that the sentence is in the past tense, we need to use the past perfect tense to indicate an action that happened before another past action.
The correct answer is had left because it correctly uses the past perfect tense.
Explanation:
- The sentence is in the past tense, indicated by the phrase "by the time we got there."
- The action of Marcia leaving occurred before the time we arrived.
- The past perfect tense, "had left," is used to indicate an action that happened before another past action.
- The other options, "left," "leaves," and "have left," do not correctly convey the sequence of events in the past.
To summarize:
- The correct verb form to fill in the blank is had left.
- This is because the sentence is in the past tense, and the past perfect tense is used to indicate an action that happened before another past action.

The correct answer is A: had taken. Let's break down the reasoning behind this choice:
- The verb "realized" indicates that the action of taking the wrong book from the library happened in the past.
- The use of the past tense is necessary to match the verb "realized" and indicate that the action of taking the wrong book occurred before the realization.
- "Had taken" is the past perfect tense, which is used to indicate an action that happened before another past action or point in time.
- The sentence structure also suggests that the action of taking the wrong book from the library happened before the realization, making the past perfect tense appropriate.
In contrast, the other options are not grammatically correct or do not match the tense and context of the sentence:
- B: "Took" is the simple past tense, which does not convey the sequence of events correctly.
- C: "Have taken" is the present perfect tense, which indicates an action that started in the past and is still ongoing or has a connection to the present. However, in this sentence, the action of taking the wrong book is clearly in the past.
- D: "Take" is the simple present tense, which does not match the past tense of the sentence or indicate the correct sequence of events.
Therefore, the correct choice is A: had taken.

To find the correct answer choice for the given sentence, let's analyze the options provided:
A:

baked

B:

have bake

C:

bake

D:

had baked

The correct answer is option D: had baked.
Explanation:
- The sentence structure suggests that the action of eating the cake happened in the past.
- The word "that" indicates that the cake was already baked before Melissa ate it.
- The verb tense used in the sentence should reflect this past action.
- Option D, "had baked," is in the past perfect tense, which indicates that the baking of the cake occurred before Melissa ate it.
- The past perfect tense is formed by using the auxiliary verb "had" followed by the past participle of the verb "bake."
In summary, the correct answer is option D: "had baked," as it correctly conveys the past action of baking the cake before Melissa ate it.

Explanation:
The correct answer to the question is option C: "had left." Here's why:
- The sentence is in the past tense, which means we need to use the past perfect tense to indicate an action that occurred before another past action.
- The verb "left" is the past simple form of "leave," and it indicates that the action of leaving the class happened at some point in the past.
- However, because there is another past action mentioned in the sentence (the teacher asking the question), we need to use the past perfect tense to show that leaving the class happened before the teacher asked the question.
- The past perfect tense is formed by using "had" + the past participle of the verb. In this case, the past participle of "leave" is "left."
- Therefore, the correct phrase to fill in the blank is "had left."
In summary, the sentence should be written as: "The teacher asked why I had left class early."

Andrew said that he __________ with my CD.
The correct answer is A: had done
Explanation:
- The sentence implies that Andrew did something in the past with the CD.
- The phrase "had done" is the past perfect tense, which is used to indicate an action that occurred before another past action.
- In this case, the action of Andrew doing something with the CD happened before the speaker's realization or inquiry about it.
- The other options, "did," "have done," and "has done," do not accurately convey the sequence of events in the sentence.
- "Did" is the simple past tense, which does not indicate that the action happened before another past action.
- "Have done" and "has done" are both present perfect tense, which is not appropriate for describing a past action.
In conclusion, Andrew said that he had done something with the CD.

To solve this sentence completion question, we need to determine the correct verb form to use with the subject "Susan" in the past tense.
The correct answer is option D:

had eaten

.
Here's a detailed explanation:
1. Subject: The subject of the sentence is "Susan," referring to a person.
2. Verb tense: Since the sentence is in the past tense, we need to use a past tense verb form.
3. Verb options:
- Option A:

have ate

- This uses the present tense "have" with the past tense "ate," which is incorrect. The verb forms should agree in tense.
- Option B:

have eaten

- This uses the present perfect tense "have" with the past participle "eaten." While this is grammatically correct, it doesn't match the past tense of the sentence.
- Option C:

has ate

- This uses the present tense "has" with the past tense "ate," which is incorrect. The verb forms should agree in tense.
- Option D:

had eaten

- This uses the past perfect tense "had" with the past participle "eaten." This is the correct verb form to use in this sentence, indicating that Susan had already eaten the cake before or during the party.
In conclusion, the correct verb form to complete the sentence is "had eaten," making option D the correct answer.

Here's why:

• "Have written" is the present perfect tense, which is used for actions completed at an indefinite time in the past or actions that began in the past and continue up to the present.
• In this context, the teacher correcting your composition implies a completed action in the past.
• "Had written" is the past perfect tense, which is used for actions completed before another past action. This is the most suitable tense for this scenario because the correction happened after the composition was written.

"Have wrote" is grammatically incorrect. The past participle of "write" is "written."

The correct answer is option A: had been.

Explanation:

To determine the correct answer, we need to understand the context and the tense of the sentence. Let's break it down:
- The sentence is talking about a past event: "The last time I was there."
- The speaker is referring to a specific point in the past when they visited the restaurant.
- We need to use the past perfect tense to indicate that the event happened before another past event.
Now let's analyze the options:
A: had been - This is the correct answer as it uses the past perfect tense to indicate that the restaurant was good before the speaker's last visit.
B: have been - This is incorrect because it uses the present perfect tense, which is not suitable for the past event being discussed.
C: been - This is incorrect because it is not a complete verb form. It needs an auxiliary verb to be complete.
D: be - This is incorrect because it is in the present tense, not suitable for the past event being discussed.
In conclusion, the correct answer is option A: had been, as it correctly conveys the past event and the sequence of events in the sentence.
