Final answer:
The statement illustrates an example of passive voice, where the subject receives the action instead of performing it. In passive voice, the actor may not be mentioned, allowing focus on the action itself.
Step-by-step explanation:
The following statement is an example of passive voice: 1) passive 2) first person 3) soprano 4) active.
In English grammar, there is a distinction between the active voice and the passive voice. Active voice sentences are structured so that the subject performs the action dictated by the verb. Contrastingly, in sentences written in passive voice, the subject is the receiver of the action. Frequently in passive constructions, the doer of the action may not even be mentioned, providing a way for writers to omit the actor when the focus is on the action itself or when the actor is unknown or irrelevant.
Examples of passive voice include sentences like 'A survey of 300 students was conducted' where the survey is the subject receiving the action of being conducted, without specifying who conducted it. In active voice, this would be something like 'The research team conducted a survey of 300 students,' where the research team is the subject performing the action.
