Change the following statement into passive voice.
Has the price rise affected all the people?
A. Have all the people been affected by the price rise?
B. Are all the people being affected by the price rise?
C. Had all the people being affected by the price rise?
D. Are all the people affected by the price rise?

Hint: In grammar, the voice of a verb is defined as a tool to explain the connection between the action that the verb expresses, and the participants identified by its arguments (subject, object, etc.). Most of the literature we read, and study uses active voice like “she eats the pie”. Here, we can see that the doer or subject is ‘she’ who is doing the verb (eating) and the object is the pie. But if we convert the object (pie) to the subject, then the sentence will be something like this: ‘The pie is eaten by her”. This is an example of passive voice.

Complete step by step answer:
1. In order to change a statement in active voice to passive voice, several things have to be carefully studied. Firstly, it is very important to identify the tense of the sentence. Then, the subject and the object should be identified. For example, in “Has the price rise affected all the people?”, the subject is ‘the price rise’, the object is ‘all the people’ and the tense of the sentence is ‘Present Perfect’.
2. Then, the positions of the subject and the object should be replaced. Here, ‘the price rise’ will go to the place of ‘all the people’ and ‘all the people’ will shift to the position of ‘the price rise’.
3. As the sentence is in the present perfect tense, 'been' will be added after the subject of the transformed sentence.
4. Rest all remains the same.
5. The sentence that we now find is:“Have all the people been affected by the price rise?”

Therefore, the correct answer to this question is option A.

Note:
We can represent the action in a sentence using two ways. They are namely active and passive voices. Active voice is characterized by the literature where the subject is doing the action (verb). But, in passive voice, the object becomes the subject. In some cases, the uses of passive voices become compulsory.
