Question

Passive voice of: Did he buy a car ?

• A. Was a car bought by him ?
• B. Did car bought by him?
• C. Did a car bought by him?
• D. Were a car bought by him ?

Hint:

To form a passive question, start with the auxiliary verb (a form of 'to be' or a modal verb), then the new subject, then the past participle. Don't use 'do', 'does', or 'did'.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This requires converting an interrogative sentence (a yes/no question) from the active voice to the passive voice. The tense is simple past.

Step 2: Key Rules for Conversion:
1. Identify Subject, Verb, Object: The subject is 'he', the verb is 'buy', and the object is 'a car'.
2. Make Object the Subject: The object 'a car' becomes the new subject.
3. Change Verb Form: The active question starts with 'Did'. The passive question will start with the appropriate form of 'to be' for the simple past, which is 'Was' or 'Were'. Since the new subject 'a car' is singular, we use 'Was'.
4. Structure the Question: The structure for a simple past passive question is `Was/Were + new subject + past participle + by + agent?`. The past participle of 'buy' is 'bought'.
5. Make Active Subject the Agent: The active subject 'he' becomes the agent 'by him'.

Step 3: Detailed Explanation:
- Active: "Did he buy a car?"
- The new subject is 'a car' (singular). So, the question starts with 'Was'.
- The past participle is 'bought'.
- The agent is 'by him'.
- Passive Question: "Was a car bought by him?"
Let's check the options:
(A) Correct structure and agreement.
(B) & (C) Incorrect structure. Passive questions don't use 'Did'.
(D) Incorrect agreement ('Were' is plural, 'a car' is singular).

Step 4: Final Answer:
The correct passive voice is Was a car bought by him ?.
