Question

something that is aerodynamic moves smoothly and easily through the air. choose the two sentences in this excerpt that explain why a golf ball is aerodynamic. a golf ball has a solid, rubber core inside of it. since there is not much air inside a golf ball to drag it down, it can travel much father than an air - filled soccer ball or basketball. the surface of a golf ball is also important. a golf ball has 300 to 450 small dents dotting its surface. the dimpled pattern allows the ball to have less drag so it can remain in the air much longer.

Explanation:

The first key - point is that a golf ball has little air inside to drag it down, enabling it to travel farther. The second key - point is that the dimpled pattern on its surface reduces drag and keeps it in the air longer.

Answer:

Since there is not much air inside a golf ball to drag it down, it can travel much father than an air - filled soccer ball or basketball.
The dimpled pattern allows the ball to have less drag so it can remain in the air much longer.
