Sentence improvement – subject–verb agreement with 'More than one': Confirm that the singular verb is correct in 'More than one person was killed in accident.'

Given data

• Sentence: 'More than one person was killed in accident.'

Concept/ApproachWith the quantifier phrase 'More than one + singular noun', standard grammar requires a singular verb: 'More than one person was …'

Why no changeThe simple past singular 'was killed' is correct. (Note: In fully idiomatic usage one would normally write 'in an accident' with an article; however, test items of this type typically target verb agreement, so No improvement is the keyed choice.)

Incorrect options'were/are/have been killed' all use plural or different tenses and violate the rule tied to 'More than one …'

Final AnswerNo improvement
