Ex Input:
Question: If Milo is listening to the radio and he moves closer to the radio in the room, what happens to the sound waves entering his ear? 
 Option1: they spread out less 
 Option2: they spread out more

Ex Output:
they spread out less


Ex Input:
Question: Compared to a wave in the ocean, would a ripple in a pond caused by a drop of rain have 
 Option1: more closely spaced particles in its rarefactions? 
 Option2: more distantly spaced particles in its rarefactions 
 Explanation: Places where particles of a medium crowd closer together are called compressions, and places where the particles spread farther apart are called rarefactions. The more energy the wave has, the closer together the particles are in compressions and the farther apart they are in rarefactions.

Ex Output:

more closely spaced particles in its rarefactions?
