Question

Which of the following are in the passive voice ?
(a) Rioting workers were identified and persecuted.
(b) The living room is swept and dusted everyday.
(c) The class photograph will be taken tomorrow.
(d) The case was investigated rather clumsily.

Accepted Answer

Option 4 is the correct answer because all the sentences listed in the question are indeed in the passive voice. Let's analyze each sentence to understand why they are in passive voice:

1. **Sentence (a): "Rioting workers were identified and persecuted."**
   - In this sentence, the focus is on the "rioting workers" who are the recipients of the actions "identified" and "persecuted." The doer of the action is not mentioned, which is a characteristic of passive voice. The structure "were identified and persecuted" clearly indicates passive construction.

2. **Sentence (b): "The living room is swept and dusted everyday."**
   - Here, the subject "the living room" is receiving the actions "swept" and "dusted." The sentence does not specify who performs these actions, which is typical of passive voice. The use of "is swept and dusted" confirms the passive voice structure.

3. **Sentence (c): "The class photograph will be taken tomorrow."**
   - In this sentence, "the class photograph" is the subject that will receive the action "taken." The doer of the action is not mentioned, aligning with the passive voice structure. The phrase "will be taken" is a clear indicator of passive voice.

4. **Sentence (d): "The case was investigated rather clumsily."**
   - The subject "the case" is the recipient of the action "investigated." The sentence does not specify who conducted the investigation, which is a hallmark of passive voice. The structure "was investigated" confirms the passive voice usage.

Now, let's explain why the other options are incorrect:

- **Option 1: (a) and (b)** is incorrect because it excludes sentences (c) and (d), which are also in passive voice.
- **Option 2: (b) and (c)** is incorrect because it excludes sentences (a) and (d), which are also in passive voice.
- **Option 3: (a), (c), and (d)** is incorrect because it excludes sentence (b), which is also in passive voice.

Therefore, Option 4 is the only correct choice as it includes all sentences (a), (b), (c), and (d), each of which is in the passive voice.
