Question

we made him our secretary change the voice ​

Answer 1

He was made secretary by us.

• The passive voice describes interest in the element that experiences a change, instead of the element that is performing the change.
• When the emphasis is on either the thing or the person affected by the action, this voice is used.
• For example -  Active: Roy reads a newspaper   Passive: A newspaper is read by Roy
• In the given sentence, the emphasis is on the person who is a secretary now.
• Thus, the correct sentence is - He was made secretary by us.
