Question Stats:

63% (01:00) correct 36% (00:24) wrong based on 7 sessions
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 10-year low.

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

Ans B ,as it proves the last year 1.2 percent was lower than the annual 4 percent stable inflation rate, so the last yr inflation rate decreased.
so we can nt say inflation is "upward trend".

B as it is the best statement which weakens the word "Upward Trend".

A)The inflation figures were computed on the basis of a representative sample of economic data rather than all of the available data.
>> Not related.
(B)Last year a dip in oil prices brought inflation temporarily below its recent stable annual level of 4 percent.
>> Yes. This explains the reasom for last year's inflation rate and also mentions 4 percent is the stable level. And so it weakens the argument that the inflation is increasing.
(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.
>> Supports the argument.
(D)The 1.2 percent rate of inflation last year represented a 10-year low.
>> This shows 1.2 is the 10 year low, but do not say if 4 is a higher value of an average value.
(E)Government intervention cannot affect the rate of inflation to any significant degree.
>> Not related.

We can clear see that A , C, E are out of scope.

Between B and D. B wins , since there are a few ambiguities with D.
