>我的问题：</P><br /><

>The answer is A.<br />I chose D.<br /><br />It is hard to tell the real meaning of the question. </P><br /><

>I am not clear, whether the sentence means,<br /><br />1: Q, in support of which one of the following hypotheses, has a response serve to counter M's use of the evidence?<br />= Q has a response to M, using which of the following hypotheses?<br /><br />2: Q, has a response to M's evidence. Which following hypotheses is used by M to support his idea?<br /><br />The answer is in favor of the second understanding. I just can't tell the 1st from the 2nd.<br /><br />Would you please explain to me?<br />Thanks a lot!<br /></P><br /><div align="right"><font color="#000066">[此贴子已经被作者于2005-2-6 21:42:19编辑过]</font></div>

>老美的解答：</P><DIV>Well, I did not write the test, and i can assure you i did not like them either but I am not sure I understand why the answer is A, </DIV><DIV> </DIV><DIV>I don't think the answer is D because there is nothing that Q or M say that directly addresses genetic predispositions and handedness. For all we know, the "naturally" right handed kids may not have been "forced" be right handed, but watched their parents (or tv stars) who were righthanded and became righthanded as a matter of learned behavior--not genetic disposition.</DIV><DIV> </DIV><DIV>However, as to A, for all we know all the people who survived to 90 were in fact born right handed; it is possible that those who were born left handed were, for whatever reason, less likely to live long. Q does not seem to address this possibility. Of course, Q's response may be consistent with the possibility that some of the right handed people who get old were born left handed, but it does not preclude the possibility that they were not. I suppose the burden would be on M to show that those who lived longer were all born  right handed or were unforced righthanders---something that is possible based on all that M and Q says (if not likely perhaps).</DIV>

><FONT face=Verdana color=#000066 size=2>Thanks a lot 蓝色的心, very good sharing ! </FONT></P><

><FONT face=Verdana color=#000066 size=2>To put thing short, this is a question asking for an inference strengthened by Q and weakened by M, whatever the assumption is, no bearing at all, and one of the approach to this, is to pick up the one that M against, among those inferences (yes, there are many) Q support.</FONT></P>
