Change the voice of the following sentence.
The fort has been guarded by moats and well-trained soldiers.
Show answer & explanation
Correct answer: B
Explanation
Correct Answer
Moats and well-trained soldiers have guarded the fort.
Explanation
Voice Identification: The original sentence is written in the passive voice, identified by the structure has been guarded and the agent introduction by moats and well-trained soldiers.
Subject-Verb Agreement: When converting to the active voice, the compound agent "Moats and well-trained soldiers" becomes the new plural subject. This requires the plural auxiliary verb have instead of the singular has.
Tense Conversion: The present perfect passive layout (has/have + been + V3) reverts cleanly into the present perfect active layout (has/have + V3), dropping the passive marker been and the preposition by.
Key Points
Word: Moats and well-trained soldiers have guarded the fort.
Meaning: The grammatically correct active voice configuration of the provided passive sentence.
Grammatical Role: Active declarative clause (functions to place the actual doers of the action in the subject position).
