OG-166一道削弱题.

OG-166

166. 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.

(C) Increases in the pay of some workers are tied to the level of inflation, and at an inflation rate of 4 percent or above, these pay raises constitute a force causing further inflation.

(D) The 1.2 percent rate of inflation last year represented a ten-year low.

(E) Government intervention cannot affect the rate of inflation to any significant degree.

According to choice B, last year’s inflation figure was an anomaly, and inflation has returned to its recent stable level. There is thus less reason to conclude that inflation will rise any further, making B the best answer.

So long as the sample on which the figures are based is representative, there is no reason to doubt that they are essentially accurate, so choice A does not affect the argument.

请问NN们,为什么A不对呀,OG的解释我不太明白.想的好辛苦呀!

怎么没人理我呀,请斑竹能否给解答一下.

我来试着回答看看

这题的题干主要是说 去年的inflation rate是1.2％，但今年是4%，因此可以推论inflation rate是上升趋势，明年会更高。

A) inflation figures 是由代表性的经济数据计算出来，而非所有可能的数据

因此OG给的解释 So long as the sample on which the figures are based is representative, there is no reason to doubt that they are essentially accurate, so choice A does not affect the argument.

只要数据具代表性，没有理由怀疑这个预测的正确性。

我想你会错，应该是在于你延伸出，不是由所有可能的数据(all of the available data)计算出的inflation rate，所以认为A选项削弱本题。 注意：题目中或答案里都没有提到这个可能性，我也常错在过度延伸问题。
