Question

Choose appropriate verb forms to fill in the blanks:

I saw an accident last night. Somebody __________ (call) an ambulance but nobody ___________ (injure) so the ambulance __________ (not/need).

• A. had called; injured; not needed
• B. called; was injured; wasn't needed
• C. had called; was injured; wasn't needed
• D. had called; injured; was not needed.

Answer 1

The correct option is B called; was injured; wasn't needed

The given sentence narrates an incident that happened in the past "last night".

Option B: 'Called', 'was injured' and 'wasn't needed' are all in simple past tense. They express actions that happened in the past, hence option B is correct.

Option A: 'Had called' is in past perfect tense.

'Injured' is a past tense verb in active voice. The subject 'nobody' experiences the action 'was injured' so the clause 'but nobody...' is in passive voice.

'Not needed' is incomplete. Without a helping verb like 'was', it does not express any tense nor does it form a complete sentence.

Option C: 'Had called' expresses the past perfect. It states an action that completed in the past, before another action took place in the past. The given sentence does not present that tense.

Option D: 'Injured' is an active voice verb.

Hence options A, C and D are wrong.
