### HideShow timer Statistics

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 seems to be the answer.

I think D is weakening the argument.

This is dead set C.

Here we are not concerned with how loud music was played but which 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.

Nothing to do within Nursery A... Out.

(B) Nursery A contained 15 percent more premature babies than nursery B.
This could be strengthening, but premature babies are not dealt with here. Out

(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.
This is the correct one...

(D) The music played in nursery A was louder than that played in nursery B.
Volume is not dealt with in the argument. Out

(E) The ratio of nurses to newborns in nursery B was 1 to 4; in nursery A, it was 1 to 6.

Number of nurses is again not dealt with. Out.
