Task: Question Generation
Input (English): Background Paragraph: A car’s gas pedal, like the one in Figure below , is sometimes called the accelerator. That’s because it controls the acceleration of the car. Pressing down on the gas pedal gives the car more gas and causes the car to speed up. Letting up on the gas pedal gives the car less gas and causes the car to slow down. Whenever an object speeds up, slows down, or changes direction, it accelerates. Acceleration is a measure of the change in velocity of a moving object. Acceleration occurs whenever an object is acted upon by an unbalanced force. 
Story: Eric is driving on a highway. His exit is coming up soon so he let's up on the gas a little and makes a left turn onto the exit. After a short way he pulls into a parking lot reaching his destination.
Output (English): Given a car is accelerating, is it being acted upon by a balanced or unbalanced force?
