标题: 最后一道CR！ [打印本页]
作者: samgxs 时间: 2002-11-15 19:00 标题: 最后一道CR！
Arguing that there was no trade between Europe and East Asia in the early Middle Ages because there are no written records of such trade is like arguing that the yeti, an apellke creature supposedly existing in the Himalayas does not exist because there have been no scientifically confirmed sightings. A verifiable sighting of the yeti would prove that the creature does exist but the absence of sightings cannot prove that it does not.
Which one best counters the argument?
Answer: any trade between Europe and East Asia in the early Middle Ages would necessarily have been of very low volume and would have involved high-priced items, such as precious metals and silk.
My answer: There have been no confirmed sightings of the yeti, but there is indirect evidence, such as footprints, which if it is accepted as authentic would establish the yeti’s existence.

In my opinion, why that the above-mentioned answer is the answer shows that we should always look for something to weaken an assumption, instead of something that raises another reason, which is not the best rebuttal.
There are many examples, which I have noticed in CR, the right answer is very often the one that addresses something in the original infor.

没错，答案就是这，但是我做的是一本很不正式的老管出的书，有不少错误。

哈哈，我想我知道问题所在了：）因为你用了老管的书，他的东西，不充分性用的极悬，当然我也用他的方法就是了。
首先，你认为对的的答案错误，在于，这个逻辑错误是类比错误，你不应该驳斥原文已经认为对的证据（ets认为这是抬杠），而应该找新的证据来证明结论的错误。所以你不应该原文论据。
正确的答案，认为“量少，并且演进为其他形式了”因此你就找不到原来的证据了。
从有关无关说，trade 和volume 原文都提到了，volume被认为是0。当然有关了。
