The correct active form of the sentence is:
"The witness made a decision to stay silent in this case."
Show answer & explanation
Correct answer: B
Explanation
Correct Answer: The witness chose to stay silent in this case.
Explanation:
The phrase made a decision expresses past action and is concisely replaced by the past tense verb chose (or decided).
The verb choose is followed by a to-infinitive (to + V1), making to stay silent grammatically correct.
All contextual elements from the original sentence, specifically the phrase in this case, must be retained completely.
