OG11th-Q39

[stevenyu]

Last year the rate of inflation was 1.2 percent, but during the current year it has been 4percent. 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?
ans(B)
Last year a dip in oil prices brought inflation temporarily below its recenet stable annual level of 4 percent.

想請問一下…題型是要weaken，那不是要證實他所推斷明年通膨會上升是錯誤的，那答案用油價下跌來說明去年通膨只有1.2percent，這樣不是更支持他的論典了嗎??拜託好心人告訴我…我的想法哪裡錯了???

結論:去年1.2 今年4 明年會更高
weaken: 油價不會一年比一年高

(B)說明去年1.2 是不正常的,因為油價下跌o 正常的是 4,因此明年也會是4,如果沒意外
