Mallory conducts a test with a model airplane powered by an elastic band propeller. She constructs the model plane and launches it three times. Before each launch, she twists the elastic band a different number of times. The results of her test are shown in the table and graph shown.

Based on the information in the table and in the graph, which of the following questions is Mallory most likely trying to test?

a)

How does an elastic band affect the drag on a model airplane?

b)

How does an elastic band affect the speed of a model airplane?

c)

How does the number of twists of the elastic band affect the distance a model airplane

travels?

d)

How does the number of twists of the elastic band affect the time a model airplane is

in the air?
