15. M: It is almost impossible to find a person between the ages of 85 an 90 who primarily uses the left hand.
Q: Seventy to ninety years ago, however, children were published for using their left hands to eat or to write and were forced to use their right hands.
Q's response serves to counter any use by M of the evidence about 85 to 90 year olds in supports of which one of the following hypotheses?
(A) Being born right-handed confers a survival advantage.
(B) Societal attitudes toward handedness differ at different times.
(C) Forcing a person to switch from a preferred hand is harmless.
(D) Handedness is a product of both genetic predisposition and social pressures.
(E) Physical habits learned in school often persist in old age.
除请教此题思路以外，另请问题干部分如何准确理解？
问题的意思是: M用他的证据支持以下哪种观点时, Q说的话可以作为反驳
M:80-90的人中几乎找不到左撇子
Q:70-90年前小孩被迫不用左手用右手
思路: Q的话能够WEAKEN 答案+M的话
ANSWER 是A: 如果M认为people born right-handed have a survial advantage, and cite the evidence stated in the stimulus, i.e. people aged 85-90 are almost all righthanded.
Q can then be the counter-evidence: those people are probably not born right-handed. Rather. some of them were born left-handed , but were forced to become right-handed
If choose D, Q's response will serve to support rather than counter
懂了，是题干没看懂！谢谢！！
你真神，我在没看懂题干的情况下恰好选的D,你竟然主动解释了D.
Q's response serves to counter any use by M of the evidence about 85 to 90 year olds in supports of which one of the following hypotheses? Q的回答可用于反对那些可用M证据来支持的下述假象？ 答案应被M支持，却又被Q反对。
