Task: Question Generation
Input (English): Background Paragraph: The frequency of a wave is the same as the frequency of the vibrations that caused the wave. For example, to generate a higher-frequency wave in a rope, you must move the rope up and down more quickly. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude. You can see examples of different frequencies in the Figure below (Amplitude is the distance that particles of the medium move when the energy of a wave passes through them.). 
Story: John was tuning his musical instruments with two tuning forks, fork A and fork B. He produced higher frequency with fork A and lower frequency with fork B. Interestingly, both frequencies had the same amplitude.
Output (English): Would fork B needed John to move it more or less quickly than fork A?
