举个例子。 很简单的一道题。 是OG13 CR32 Last year the rate of inflation was 1.2 percent, but for the current year it has been 4 percent. We can conclude that inflation is on an upward trend and the rate will be still higher next year.
Which of the following, if true, most seriously weakens the conclusion above?
A. The inflation figures were computed on the basis of a representative sample of economic data rather than all of the available data.
B. Last year a dip in oil prices brought inflation temporarily below its recent stable annual level of 4 percent.
B是正确选项。
英吉讲A为什么不对直接说“原文没有说数据来源,所以是无关选项。”
那么我为什么不能说“B项中原文也没有说a dip in old price,所以也是无关选项呢?
我觉得正确思路应该是这样的, A项说数据来源如果要削弱缺少一个逻辑关系就是,all available data是能推出结论的, 而representative sample of economic data 是不全面的,是不能推出结论的。但是缺少的这个逻辑关系是自己主观联想的,所以不能选择。
逻辑题的加强和削弱的逻辑关系不能含有主观联想的成分。
而不仅仅是像英吉所说的那样因为没说所以可以迅速排除。。求NN们指点啊!!!!!! |
