35.    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.
(0   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 10-year low.
(E)    Government intervention cannot affect the rate
of inflation to any significant degree.
正确答案是B，OG上的解释我还是看不太明白，请大牛指点，谢谢了~~

用排除法可以做，但我想知道B正确的理由。。。

inflation is on an upward trend and the rate will be still higher next year
这里说明年还应该涨，是upward trend。。所以下一年inflation应该还得增加。。

b说去年的低inflation是个特例，实际trend是stable的，不是upward的，那么inflation应该还是4％，自然就weaken了。。
