Answer 1

The best response is:

**He will uses less force with the broom.**

Using a broom generally allows for more effective sweeping of glass because it covers a larger area and can loosen debris with less effort compared to a hand brush, which requires more force applied over a smaller area. This means that the broom can make the task easier and more efficient, requiring less physical effort from the student.
