In an experiment, two different types of recorded music were played for neonates in adjacent nurseries in a hospital. In nursery A, classical music was played; in nursery B, rock music was played. After two weeks, it was found that the babies in nursery A cried less, suffered fewer minor ailments, and gained more weight than did the babies in nursery B.
Which of the following additional experimental data would support the hypothesis that classical music is beneficial to the development of newborn?
(A) The neonates in a nursery where no music was played fared better than those in nursery B.
(B) Nursery A contained 15 percent more premature babies than nursery B.
(C) The newborns in nursery A cried less, suffered fewer minor ailments, and gained more weight than did newborns in a nursery with no music.
(D) The music played in nursery A was louder than that played in nursery B.
(E) The ratio of nurses to newborns in nursery B was 1 to 4; in nursery A, it was 1 to 6.

C)...we know that A is better than B. the author concludes that the condition that made A better than B is better in general. how can we support that ? when the condition benefits A as well as C. more benefit than do not benefit. A+C>B.
If your mind can conceive it and your heart can believe it, have faith that you can achieve it.
neophytes in A fared well than those in B.
Well rather than the benefit of classical music , it migh be the adverse effect of pop music which caused the imbalace.
But it is proved that A fared well than neophytes without music, then not only does classical music improve the condition of babies but does so more than what pop does.
Even (E) struck me for a moment, but then, assuming a hypothetical case in which there are three nurseries A,B and C with the nurse to babies ratio being the same and no music being played in A, classical music being played in B and rock music in C.
In such a case, only (C) would strengthen the argument that Classical music is beneficial. Hence (C).
