Answer 1

he opened his bag at midday punctually.

Answer 2

Punctually at midday, the bag was opened by him.

• The sentence can also be written as-

The bag was opened by him punctually at midday.

• The given sentence is in the active voice and we have changed into the passive form.
• In case of active voice, the subject directly performs an action.

So, the structure is: Subject+ verb+ object

• In case of passive voice, the subject interchanges its position with the object.

So the structure is: Object+ verb+ subject.
