Final answer:
The sentences provided feature subjects that are both doers and receivers. Shera is the doer, actively waving, while in the other sentences, the subjects are receivers, being appreciated, tricked, and manufactured. Passive voice is used for the receiver-focused sentences.
Step-by-step explanation:
In answering the question, we will identify whether the subjects in the sentence are doers or receivers of the action. To clarify, a doer is the subject performing the action, and a receiver is the subject that the action is being done to.
- Shera waved to the people at the CWG closing ceremony. - Shera is the doer of the action.
- Our performance was appreciated by the world. - Our performance is the receiver of the action.
- The tiger was tricked by the rabbit. - The tiger is the receiver of the action.
- Robots are manufactured in India. - Robots are the receiver of the action.
It's important to note that in sentences b, c, and d, the verb forms used are in the passive voice, which typically has the receiver of the action as the subject of the sentence. In contrast, sentence a uses the active voice, making the doer the subject.
