Explanation

Correct Narration Change:

The original sentence (Teacher said to them, "Don't make noise") is a command (strict instruction).

In indirect speech, "ordered" is the most appropriate verb for strong commands like this.

The imperative "Don’t make noise" changes to "not to make noise" (infinitive structure in reported speech).

Explanation

Correct Passive Voice Conversion: The original sentence "Do you imitate others?" is in the active voice.

Its passive form is "Are others imitated by you?" (subject + auxiliary verb + past participle + agent).

Explanation

A letter was being written to her father by Mona.

The sentence is in past continuous tense: was writing.

In passive voice, past continuous becomes was being + past participle → was being written.
