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.

答案是A
这道题目的问题到底是说Q的假设还是M的假设? 如果是后者, 正常的语序应该是怎样的?? 谢谢.

The answer is Q's hypotheses.

The answer is not Q's hypothesis, but M's

I also chose E) as right answer, that is just Q's hypothesis. A) is M's hypothesis, but how to judge the question? I mean it's not in right/normal order, how to say the question in the normal order ? Thx!

E) is not Q's hypothesis for school can not be infered.

M-前提: 找不到80-90岁的左手使用者
Q- 解释 因为被强制改了

问: Q 的用来反对M的解释是基于下边哪个假设的.

M 说没有了, Q 说有, 只是被强制改了. ---反对了M
为啥被强制改? 因为假设是: 右手更有利

不知道是否这末想清楚些.

Mission

M: It is almost impossible to find a person between the ages of 85 an 90 who primarily uses the left hand.

     the hypothesis of M: people using the right hand live longer than people using the left
                                  hand.  which is to say, people using right hand have more
                                  survival advantage than people using left hand.
              evidence:       all the people at the age of 80 or 90 are right 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.

           oppose the evidence:  not all the people are born right hands. which means that there might be some people of 80 or 90 are born left hand ,but later are forced to  change to use right hand.

           the M's hypothesis is not valid

i still chose E) at that time, 因为不理解问题的意思. 我现在仍然认为他是在问: Q 的用来反对M的解释是基于Q作出的下边哪个假设的. 如果理解为反对M的假设, 正常的语序应该是怎样的? 谢谢.

jq,

You misunderstood the question. What the question asked was the hypothesis of M's. I think the question can be re-written as:
Q counters M's evidence, which is used to support which of the following hypothesis.

So the answer is M's hypothesis supported by M's evidence.

If I can get the main part of the question like this:

Q's response serves to counter any use of the evidence in support of which one of the following hypotheses?

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?
