Question

Change the following into passive voice:
Why does he beat his brother?

Hint:

For changing interrogative sentences to passive voice, first, mentally change the assertive form (He beats his brother → His brother is beaten by him) and then convert it back into a question (Is his brother beaten by him?), finally adding the Wh-word at the beginning.

Answer 1

Step 1: Understanding the Question:
The task is to change an active voice sentence into the passive voice. The given sentence is in the Simple Present tense and is an interrogative sentence starting with a 'Wh-' word.
Step 2: Key Concepts for Conversion:

Identify S-V-O: Subject (he), Verb (beat), Object (his brother).
In the passive voice, the object becomes the new subject.
The verb form changes to a 'be' verb (is/am/are for simple present) + the past participle (V3) of the main verb. The V3 of 'beat' is 'beaten'.
The original subject becomes the agent, introduced by 'by'.
For 'Wh-' questions, the 'Wh-' word remains at the beginning. The auxiliary verb comes before the new subject to maintain the question format.
Step 3: Applying the Rules:

Active structure: Wh-word + does + subject + V1 + object?
Passive structure: Wh-word + is/am/are + new subject (old object) + V3 + by + agent (old subject)?
Wh-word: Why
New subject: his brother (singular, so use 'is')
V3: beaten
Agent: by him
Combining these parts gives: Why is his brother beaten by him?
