1. In Malsenia sales of classical records are soaring. The buyers responsible for this boom are quite new to classical music and were drawn to it either by classical scores from television commercials or by theme tunes introducing major sports events on television. Audiences at classical concerts, however, are continually shrinking in Malsenia. It can be concluded from this that the new Malsenian converts to classical music, having initially experienced this music as recorded music, are most comfortable with classical music as recorded music and really have no desire to hear live performances.

The argument assumes which one of the following?

B> At least some of the new Malsenian buyers of classical records have available to them the option of attending calssical concerts.

C> The number of classical concerts performed in Malsenia has not decreaed in response to smaller audiences.

D> The classical records available in Malsenia are, for the most part, not recordings of actual public concerts.



2. Brain scans of people exposed to certain neurotoxins reveal brain damage identical to that found in people suffering from Parkinson's disease. This fact shows not only that these neurotoxins cause this type of brain damage, but also that the brain damage itself causes Parkinson's disease. Thus brain scans can be used to determine who is likely to develop Parkinson's disease.

The argument contains which one of the following reasoning errors?

A> It fails to establish that other methods that can be used to diagnose Parkinson's disease are less accurate than brain scans.

B> It overestimates the importance of early diagnosis in determining appropriate treatments for people suffering from Parkinso's disease.

C> It mistakes a correlation between the type of brain damage described and Parkinson's disease for a causal relatin between the two.

1. the answer is C. 本人也认为是B, 还请高手指点!

记得在KAPLAN中学习到:
如果找ASSUPTION,就先把答案否定掉,然后放到原来的文章里,看是不是
1。能WEAKEN结论
2。能与原来的现象吻合(不要和原来的现象冲突)
否定B,得到:
没有人可以去听音乐会
显然可以WEAKEN结论,但是和那个“听音乐会人数减少”冲突了:(
否定C,得到:
音乐会数量减少了
也可以WEAKEN结论,而且不和音乐会人数减少冲突,尤其是它点出了人数减少这个因素。:)

至于2。
我觉得是不是有可能题目不对。。。:(
个人认为C是不是更恰当一些。。

licheng, 对1 的回答精彩
作者: raonx    时间: 2002-9-3 22:48

对于2.

我个人认为C对,但答案好象是B. 从推理过程看应是将相关性认做因果性 所以C
好象题目中并未overestimates the importance ....我也不太理解只是将答案记住了.
还请高人指点.

多谢licheng的指点! 我明白了你的思路, 觉得很正确. 但对此题的解释我还是不太明白:
否定B,是说那些new classical buyers没有机会听音乐会, 但原文"听音乐会的人数减少"并不限定于new buyers,所以我不明白 licheng 所谓的冲突何在?

thx!

1.Answer is C. It is accord with " excluding the other reason" .  For this item, the conclusion is: that the new Malsenian converts to classical music, having initially experienced this music as recorded music, are most comfortable with classical music as recorded music and really have no desire to hear live performances.  The assumption is the live performance is good. so it come to C.

2. I do think the answer is C.
