The aim of changing sentences from the active to the passive voice is to shift focus from the subject (the "doer") to the object (the receiver of the action). This structural change is used to emphasize the result of an action, improve objectivity, or report information when the actor is unknown or unimportant.
Core Principles of the Task
Object Becomes Subject: The receiver of the action in the active sentence becomes the subject of the passive sentence
"To Be" + Past Participle: The main verb changes to a passive form
Verb Tense Remains: The tense of the "to be" verb must match the original active verb's tense.
The "By" Agent: The original subject (if mentioned) is introduced by the preposition "by"
