Task: Explanation
Input (English): Question: Compared to a wave in the ocean, would a ripple in a pond caused by a drop of rain have 
 Answer: more closely spaced particles in its rarefactions?
Output (English): 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.
