Questions 4-5 are based on the following:
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.
5. 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.（C）
(E) The ratio of nurses to newborns in nursery B was 1 to 4; in nursery A, it was 1 to 6.
对于c不太理解，做题时倒是在b和e上犹豫不决，觉得b排除了实验前A的新生儿比B新生儿身体好的这一情况，从而支持了题目中的hypothesis, 而e是排除了A的看护程度强于B的看护程度这情况。
很困惑，请大家指点迷津！thanks
B, E 並沒有提到music...
C is correct because it compares with newborn babies有聽音樂和沒聽音樂之下 有聽音樂的newborn babies suffered fewer minor ailments and gained more weight..所有 顯然是因為是因為聽音樂的關係
up! open to discussion
欧也是选b，迷惑
现象：听古典音乐的baby比听rock的baby要cry less...
结论：听古典音乐对baby的development有好处
以上推理存在一个漏洞：可能不是古典音乐好，可能是rock音乐对baby产生很大的坏的作用。
C排除了这个漏洞。所以是perfect的支持答案。
其他答案：
A：no music，和文章的focus无关
D：谈论的是不同类型音乐的作用，没有提供任何loud与否的信息，无关
BE：貌似支持，但是其实你们觉得这两个选项支持的时候都不知不觉运用了你们自己的背景知识：谁说早生儿的情况就比其他baby差的？文章说听了古典音乐的baby就会cry less，管你是不是早生儿呢。谁说护士多就一定护理情况好的？文章没有提供任何信息。这两个答案放在OG里，ETS会说：without futher information，answer B and E alone cannot affect the hyphothesis...
班主,高!高!高!
