prep08-2-99题 helr分析法，因果与果因的问题！求助！

angela不怕孤单

99.
One of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream.  Accordingly, entrepreneurs have begun selling at gymnasiums and health clubs bottles of drinking water, labeled “SuperOXY,” that has extra oxygen dissolved in the water. Such water would be useless in improving physical performance, however, since the amount of oxygen in the blood of someone who is exercising is already more than the muscle cells can absorb.

Which of the following, if true, would serve the same function in the argument as the statement in boldface?

A. world-class athletes turn in record performances without such water
B. frequent physical exercise increases the body’s ability to take in and use oxygen
C. the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs
D. lack of oxygen is not the only factor limiting human physical performance
E. the water lost in exercising can be replaced with ordinary tap water

prep语法笔记解释：
结论句是：“Such water would be useless in improving physical performance”
这个题目我们通过读问题和原文得知，黑体字部分是原文因果推理模式的前提，也就是逻辑上的因，而问题想让我们找到一个和这个前提具有同样功能的句子，其实就是给原来结论再找到一个“因”，也就是能说明结论选项。比较像果因的CQ1：说明结果问题

我的疑问：
前提是：the amount of oxygen in the blood of someone who is exercising is already more than the muscle cells can absorb
结论是：Such water would be useless in improving physical performance
前提是因，发生在前；结论是果，发生在后。
问：什么不是因果推理模式？
考虑到这道题的问法，答案不属于因果推理中的CQ1或CQ2。虽说像果因的CQ2他因，但是原文应该是因果推理！

谢谢各位！

不明白楼主为什么要硬拿着题目套模式呢？这个题目不存在推理，就是找到一个选项可以代替黑体部分就可以了。
因为黑体部分表示的是“含氧水”没有用的原因，所以找找看哪个选项也表达的是“水没用的原因”呀。

小蘑菇开始打怪

其实这道题目我也有疑问的，就是你看分析里面说原文的思路是因果对吧，然后黑体的部分是前提原因，但是问题问的是还有什么其他的原因？那这样的话我们就可以忽略掉黑体的部分假设它就是不存在，那这个时候要求我们自己去找一个原因去解释原文中“useless”的结论也就是现象，这样的推理模式不就是果因嘛回溯原因。只不过这个原因是在选项里面的。我记得OG里面有几题也是在选项里面找原因，我不知道这样的话是不是都可以认为是果因推理模式？希望NN来帮忙解答~~

同疑问，我想的和楼上一样，可能是因为这道题问法的特殊性。CR2-91也是这种，但就是因果型。

91.       

Journalist: Every election year at this time the state government releases the financial disclosures that potential candidates must make in order to be eligible to run for office.  Among those making the required financial disclosure this year is a prominent local businessman, Arnold Bergeron.  There has often been talk in the past of Mr. Bergeron's running for governor, not least from Mr. Bergeron himself.  This year it is likely he finally will, since those who have discounted the possibility of a Bergeron candidacy have always pointed to the necessity of making financial disclosure as the main obstacle to such a candidacy.

In the journalist's argument, the two boldfaced portions play which of the following roles?

A. The first provides information without which the argument lacks force; the second states the main conclusion of the argument.
B. The first provides information without which the argument lacks force; the second states an intermediate conclusion that is used to support a further conclusion.
C. The first describes a practice that the journalist seeks to defend; the second cites a likely consequence of this practice.
D. The first states evidence bearing against the main conclusion of the argument; the second states that conclusion.
E. Each provides evidence in support of an intermediate conclusion that supports a further conclusion stated in the argument.

理论上既然结论是果了，那就应该是因果模式。

求大牛解惑！！

我的理解，原文的推理模式是因果，这个没有错误的
但是问题并不是问原文的因果逻辑链，而是让你提出一个新的原因来解释结论，也就是找他因
也就是这道题是因果推理没错，但是题目的不是要你去评估原文的因果逻辑链
举个例子
因——我昨晚睡很晚
果——我早上没起来
这个是因果逻辑链，完全没问题，
但是我要你你再找原因，解释我为什么早上没起来的
