Q:Here's a short story: Mister Bigsby rolled a baseball down two different hills. The first hill is a pile of rocks and the second hill is fresh cement. Mister Bigsby noticed that the basball travels farther down the fresh cement as opposed to the pile of rocks. This is because the fresh cement is (A) rougher (B) smoother. What is the most sensical answer between "fresh cement" and "pile of rocks"?
A:
pile of rocks
