The shuttle is moving towards the earth. It's velocity is decreasing linearly
constant acceleration).

Result:

Correct Newtonian answer (D): 8%
Correct Aristotelian answer (C or E): 69% (333 students).
Comment:

Possible conflicting considerations on the side of the students:
Is the force in the direction of motion decreasing or is the force opposite to the direction of motion increasing?
