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.
這題答案是C
當初寫的時候也有考慮到C
不過最後選了B
B:nursery A的早產兒比nurseyB多了15%,所以A的健康條件比較差,
反而最後表現較好,這樣不就是最支持假設了嗎??
