Correct Answer:
A. My bag was stolen
The question requires converting the sentence "Someone stole my bag" into its correct passive voice form.
The original sentence is in the simple past active voice, indicating an action that was completed in the past. To convert a simple past active sentence to passive voice, the structure is: object + was/were + past participle of the main verb + (by agent). When the agent ('someone', 'people', 'they') is unknown or unimportant, it is usually omitted in the passive voice.
- A: My bag was stolen. This is the correct passive voice. 'My bag' (the object) becomes the subject. The verb 'stole' (simple past active) correctly transforms into 'was stolen' (simple past of 'to be' + past participle). The agent 'someone' is correctly omitted as it is unspecified.
- B: My bag is stolen. This is in the present simple passive voice ('is stolen'), incorrectly changing the tense from past to present.
- C: My bag has stolen. This remains in the active voice (present perfect active) and implies 'my bag' performed the action, which is illogical.
- D: My bag stole. This remains in the active voice (simple past active) and implies 'my bag' performed the action, which is illogical.
