Task: Question Generation
Input (English): Background Paragraph: Electromagnetic radiation is energy that travels in waves across space as well as through matter. Most of the electromagnetic radiation on Earth comes from the sun. Like other waves, electromagnetic waves are characterized by certain wavelengths and wave frequencies. Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. Electromagnetic waves with shorter wavelengths have higher frequencies and more energy. 
Story: Chris is working in a lab that handles radioactive materials. Today he is working with Element A and Element B. When measuring element A he notes that is has a shorter wavelength than element B.
Output (English): Which element has a higher frequency, element A or element B?
