Question

They presented to all students a cheque and a certificate.

Answer 1

Answer:

The statement is in past tense; For converting it to passive voice 'The reports' is made the subject; the auxiliary verb following it should be plural since it is a plural subject; so 'handed in' is changed to 'were handed in' and the doer is introduced by preposition 'by'; so the correct answer is 'The reports were handed in by the students.'; we cannot omit 'in' after 'handed' as it changes the meaning.
