The news of his success pleased his parents.
Answer:
His parents were pleased with the news of his success.
**Rule**: Certain verbs, especially those related to emotions, often take prepositions other than 'by'. The verb 'pleased' is commonly followed by **'with'**. The active sentence is in the Simple Past Tense.
- **Correct Answer (a)**: The object 'his parents' becomes the subject. The passive verb form 'were pleased' is correct for the Simple Past. The preposition 'with' is idiomatically correct here.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present and uses the less common preposition 'by'.
- **Incorrect Answer (c)**: While 'by' is sometimes possible, 'with' is the more standard preposition for 'pleased'.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.

They consider him a genius.
Answer:
He is considered a genius.
**Rule**: In a sentence with an object and an object complement, the object becomes the subject of the passive sentence, and the complement remains. The agent ('by them') can be omitted. The sentence is in the Simple Present tense.
- **Correct Answer (d)**: The object 'him' becomes the subject 'He'. The verb 'consider' becomes 'is considered'. The object complement 'a genius' follows the verb. Omitting 'by them' is natural and common.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: Adding 'to be' is possible but not necessary with the verb 'consider'. Option (d) is more direct and concise.
66293
Did the team win the championship?
Answer:
Was the championship won by the team?
**Rule**: For an interrogative sentence in the Simple Past Tense starting with 'Did', the passive structure is **Was/Were + object + V3 + by + subject?**
- **Correct Answer (a)**: The object 'the championship' is singular, so the sentence starts with 'Was'. This is followed by the object and the past participle 'won'.
- **Incorrect Answer (b)**: 'Were' is incorrect because the subject 'the championship' is singular.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
66294
Has somebody cleaned the windows?
Answer:
Have the windows been cleaned?
**Rule**: To convert an interrogative sentence in the Present Perfect Tense to passive voice, the structure is **Has/Have + object + been + V3?** The indefinite subject 'somebody' is omitted.
- **Correct Answer (a)**: The object 'the windows' is plural, so the sentence starts with 'Have'. This is followed by the object, 'been', and the past participle 'cleaned'. The agent 'by somebody' is correctly omitted.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Perfect and unnecessarily includes the agent.
- **Incorrect Answer (d)**: This is not in the correct interrogative word order.
66295
Did the noise from the party disturb you?
Answer:
Were you disturbed by the noise from the party?
**Rule**: For an interrogative sentence in the Simple Past Tense starting with 'Did', the passive structure is **Was/Were + object + V3 + by + subject?** The verb must agree with the new subject.
- **Correct Answer (b)**: The object 'you' becomes the subject. 'You' always takes the plural verb 'were'. The past participle 'disturbed' is used correctly.
- **Incorrect Answer (a)**: 'Was' is grammatically incorrect with the pronoun 'you'.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
66296
The team was celebrating its victory.
Answer:
The victory was being celebrated by the team.
**Rule**: For a sentence in the Past Continuous Tense, the passive voice structure is **Object + was/were + being + V3 + by + Subject**.
- **Correct Answer (d)**: The object 'its victory' becomes the subject 'The victory'. Since it's singular, 'was' is used, followed by 'being' and the past participle 'celebrated'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Continuous.
66297
The team is developing a new app.
Answer:
A new app is being developed by the team.
**Rule**: For a Present Continuous Tense sentence, the passive structure is **Object + is/am/are + being + V3 + by + Subject**.
- **Correct Answer (c)**: The object 'a new app' becomes the subject. Since it is singular, 'is' is used, followed by 'being' and the past participle 'developed'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
66298
How do you operate this machine?
Answer:
How is this machine operated by you?
**Rule**: For an interrogative sentence in the Simple Present Tense starting with a 'Wh-' word, the passive structure is **Wh- word + is/am/are + object + V3 + by + subject?**
- **Correct Answer (d)**: The 'Wh-' word 'How' remains at the beginning. The object 'this machine' is singular, so 'is' is used, followed by the past participle 'operated'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (c)**: This introduces the modal 'can', which was not in the original sentence.
66299
The sudden news shocked us all.
Answer:
We all were shocked at the sudden news.
**Rule**: The verb 'shocked' in the passive voice is often followed by the preposition **'at'** (or 'by') to indicate the cause. The active sentence is in the Simple Past Tense.
- **Correct Answer (b)**: The object 'us all' becomes 'We all'. The passive verb 'were shocked' is correct for the Simple Past. The preposition 'at' is idiomatically correct here.
- **Incorrect Answer (a)**: While 'by' is possible, 'at' is very common with 'shocked'.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.

What have you been reading?
Answer:
What has been being read by you?
**Rule**: The passive voice for the Present Perfect Continuous Tense is formed with **What + has/have + been + being + V3**. This construction is extremely rare and awkward but is the grammatically correct passive form.
- **Correct Answer (d)**: This is the technically correct, though very uncommon, passive form of the Present Perfect Continuous Tense.
- **Incorrect Answer (a)**: This changes the tense to Present Perfect.
- **Incorrect Answer (b)**: This changes the tense to Past Continuous.
- **Incorrect Answer (c)**: This changes the tense to Present Continuous.
