51. Which of the following placements for the underlined portion makes it most clear that it was Rome that had expanded?

Answer and Explanation

Correct Answer is B

Explanation

The best answer is B because the meaning of the phrase "greatly expanded" is most clear in this case when it is placed directly before the noun it modifies: "city of Rome." When we read "surrounded the greatly expanded city of Rome," it is obvious that Rome itself, rather than the wall or the river, had expanded.
