English Olympiad Test: Voice - Class 10 MCQ

The correct answer is B: "Was built".
Explanation:
- The sentence is in the passive voice, as indicated by the use of the past participle form of the verb "built".
- The subject of the sentence is "This house", and the action of building the house was performed by someone else (the grandfather).
- In the passive voice, the subject receives the action of the verb rather than performing the action itself.
- The correct form of the verb "build" in the past tense passive voice is "was built".
- The other options are incorrect:
- Option A: "Built" is the past tense active voice form of the verb, which does not match the passive voice construction of the sentence.
- Option C: "Was build" is grammatically incorrect because the past participle form of the verb should be used.
- Option D: "Has built" is the present perfect active voice form of the verb, which does not match the past tense construction of the sentence.
In summary, the correct answer is B: "Was built".

Explanation:

The correct answer is B: Are preparing.

In this sentence, we need to use a verb form that indicates an ongoing action in the present. The verb "are preparing" is in the present continuous tense, which is used to describe actions happening at the moment of speaking or actions that are ongoing.

Options:

• A: Have preparing - This is an incorrect option as "have preparing" is not a grammatically correct verb form.


• B: Are preparing - This is the correct answer as it indicates an ongoing action in the present.


• C: Had preparing - This is an incorrect option as "had preparing" is not a grammatically correct verb form.


• D: Have been prepared - This is an incorrect option as "have been prepared" is in the present perfect passive tense, which does not fit the context of the sentence.

Therefore, the correct answer is B: Are preparing.

The correct answer is option A: "Have been working."
Explanation:
To determine the correct verb form, we need to consider the tense and subject of the sentence.
1. Tense: The sentence does not provide any specific timeframe, so we should use the present perfect continuous tense. This tense is used to describe an action that started in the past, is still ongoing, and may continue into the future.
2. Subject: The sentence does not provide any specific subject, so we can assume that it refers to the first person singular "I."
Now, let's analyze each option:
A: Have been working - This is the correct form. It matches the present perfect continuous tense and the subject "I."
B: Has been working - This form is incorrect because "has" is used with the third person singular subject, not "I."
C: Was working - This form is incorrect because it uses the past continuous tense, which does not convey the ongoing nature of the action.
D: Am working - This form is incorrect because it uses the present continuous tense, which does not convey the duration of five hours.
In conclusion, the correct answer is option A: "Have been working." This form matches the present perfect continuous tense and the subject "I."

The correct answer for the blank is option C: "Has been ailing". Here is the detailed explanation:
Subject-Verb Agreement:
The subject "She" is a singular third-person pronoun, so the verb form used with it should also be singular.
Verb Tense:
The sentence suggests that the action of "ailing" has been happening for some time and is still ongoing. Therefore, we need to use a verb form that indicates a past action with present relevance.
Active vs. Passive Voice:
The sentence does not require a passive voice construction as there is no object receiving the action. The focus is on the subject "She" and her state of ailing.
Options Analysis:
A. "Are ailing" - This option uses the present tense verb form "are" which is not suitable for the given sentence. Also, it is in the active voice, whereas the sentence does not require an active construction.
B. "Is ailing" - This option uses the present tense verb form "is" which is not suitable for the given sentence. Also, it is in the active voice, whereas the sentence does not require an active construction.
C. "Has been ailing" - This option uses the present perfect continuous tense verb form "has been ailing" which correctly indicates the ongoing action of ailing that started in the past and is still continuing. It is in the passive voice, which is appropriate for the sentence.
D. "Have been ailing" - This option uses the present perfect continuous tense verb form "have been ailing" which is not suitable for the singular subject "She". It is in the active voice, whereas the sentence does not require an active construction.
Therefore, the correct answer is option C: "Has been ailing".

The correct answer to fill in the blank is option A: "Have always wanted".
Explanation:
To determine the suitable active and passive verb forms to fill in the blank, let's analyze the given sentence:
"I ______ to become a successful writer."
1. "I" indicates the subject of the sentence, which means the verb should agree with the first-person singular pronoun.
2. The sentence expresses a desire or ambition to become a successful writer.
Considering these points, let's analyze each option:
A: Have always wanted
- This option uses the present perfect tense in the active voice.
- The verb "have wanted" agrees with the subject "I" and indicates a continuous desire or ambition.
- This option is correct and suitable for the given sentence.
B: Am always wanted
- This option uses the present continuous tense in the passive voice.
- The verb "am wanted" does not agree with the subject "I" and does not convey the intended meaning.
- This option is not suitable for the given sentence.
C: Was always wanted
- This option uses the past tense in the passive voice.
- The verb "was wanted" does not agree with the subject "I" and does not convey the intended meaning.
- This option is not suitable for the given sentence.
D: Am always wanting
- This option uses the present continuous tense in the active voice.
- The verb "am wanting" agrees with the subject "I," but it does not accurately convey the desired meaning of a continuous desire or ambition.
- This option is not suitable for the given sentence.
Therefore, option A, "Have always wanted," is the correct active verb form to fill in the blank.

The correct answer for this question is option C: "Was carried."

Passive verb forms:

In the given sentence, we can see that the patient could not walk, which implies that someone else had to transport him. This indicates that the patient is the receiver of the action, making the sentence passive.
Let's analyze the options:
A: Has carried
- This is an active verb form in the present perfect tense. It does not fit the context of the sentence.
B: Has been carried
- This is a passive verb form in the present perfect tense. However, the sentence is in the past tense, so this option is not suitable.
C: Was carried
- This is a passive verb form in the past tense. It correctly indicates that the patient was transported by someone else.
D: Was carrying
- This is an active verb form in the past continuous tense. It does not convey the passive meaning required by the sentence.
Therefore, the correct answer is option C: "Was carried."

The robbers ______ by the police.
To determine the correct verb form to fill in the blank, we need to consider the subject and tense of the sentence. Here, the subject is "the robbers" and the tense is not specified, so we can assume it is in the present perfect tense.
The present perfect tense is formed using the auxiliary verb "have" or "has" with the past participle form of the main verb. In this case, the main verb is "arrest."
Now let's consider the options:
A: Have arrested - This is the active form of the verb in the present perfect tense. It does not match the subject "the robbers."
B: Have been arrested - This is the passive form of the verb in the present perfect tense. It matches the subject "the robbers" and is the correct answer.
C: Was arrested - This is the passive form of the verb in the past tense. It does not match the subject "the robbers."
D: Had arrested - This is the active form of the verb in the past perfect tense. It does not match the subject "the robbers."
Therefore, the correct answer is B: Have been arrested. This form indicates that the robbers have been arrested by someone (in this case, the police).

Answer:
The correct answer is B: Has been raining.
Explanation:

• The verb form "has been" is the present perfect continuous tense in the passive voice.


• In this sentence, the action of raining started in the past and is still ongoing in the present.


• The correct sentence in the active voice would be "It has been raining since yesterday."


• The other options are incorrect because:




• A: "Is raining" is in the present simple tense and does not convey the continuous aspect of the action.


• C: "Have been raining" is in the present perfect continuous tense but uses the plural form of the subject "It," which is incorrect.


• D: "Was raining" is in the past continuous tense and does not convey the ongoing aspect of the action.

Therefore, the correct answer is B: Has been raining.

The correct answer is B:

Are asked

Explanation:
- The verb form "are asked" is the passive form of the verb "ask" in the present tense.
- In this sentence, the subject "students" is receiving the action of being asked to submit their reports.
- The passive verb form is used here because the focus is on the students being asked to do something, rather than who is asking them.
- The other options are incorrect because they use the wrong verb form or subject-verb agreement:
- A: "Have asked" is the active form, but the sentence requires the passive form.
- C: "Has asked" uses the singular form of the verb, but the subject "students" is plural.
- D: "Are asking" is the active form, but the sentence requires the passive form.

To determine the suitable active and passive verb forms for the given sentence, let's analyze the options provided:

B: Were not treating
This option uses the active verb form "were not treating," indicating that the inmates were not providing treatment. However, the sentence requires a passive verb form.
