Answer:
statue
Explanation:
The best reason for the writer to revise this sentence to be in the passive voice is to emphasize the statue.
Revised sentence in passive voice: The statue David was sculpted by the famous artist and sculptor Michelangelo in Italy in the early 1500s.
By using the passive voice, the attention is shifted from the subject (Michelangelo) to the object (the statue David). The focus is placed on the creation of the statue itself, highlighting its significance and importance rather than solely emphasizing the sculptor.
