You play a violin in the orchestra. For your concert, you play in the cafeteria. Your family records your performance so that you can listen and watch it later. On Saturday, you decide to watch it. How did it sound when you watched the recording? A.
Since the cafeteria is covered in flat surfaces, the sound waves diffract a great deal. These diffractions cause interference. In turn, the interference makes the performance crystal clear.

B.
Since the cafeteria is covered in flat surfaces, the sound waves refract a great deal. These refractions cause interference. In turn, the interference makes the performance crystal clear and beautiful.

C.
Since the cafeteria is covered in flat surfaces, the sound waves reflect a great deal. These reflections cause interference. In turn, this interference makes it difficult to hear the performance.

D.
Since the cafeteria is covered in flat surfaces, the sound waves refract a great deal. These refractions cause interference. In turn, this interference makes it difficult to hear the performance.
