C.) The amount by which the agency underestimated the GNP it projected for Goro tended to increase over time.

(Understood/accepted B is correct) but isnt cumulative amount of GNP been underestimated each year has to increase over time. The choice isnt clear, C is obviously wrong if what the test maker meant by "The amount" in C.) is just for each year.

Thanks


there is no information in the passage from which we can tell whether "the amount...increases or decreases"


Thanks & Happy new year Chesstitans... what I meant was for an example
the underestimated amount of yr 1 (Real GNP minus incorrectly estimated number) = 5 mn
yr2 (again understimated) = 4 mn
yr 3 = 7 mn
..... y10 = 5mn

so all combined 10 yrs (wrongly estimated amounts) should increase overtime...??

Thanks

Yes, the TOTAL sum of the underestimates would obviously increase, but that is not what choice (C) says. In fact, your example disproves choice (C). Choice (C) would only be accurate if the DIFFERENCE between the estimates and the actual numbers increased each year, for example:

    Year 1: underestimated by 2 million
    Year 2: underestimated by 2.5 million
    Year 3: underestimated by 3 million
    etc.

As your example shows, the amount by which the agency underestimated the GNP may have increased or decreased or remained the same year to year, for example:

    Year 1: underestimated by 2 million
    Year 2: underestimated by 2 million (amount by which they underestimated remained the same)
    Year 3: underestimated by 1 million (amount by which they underestimated DECREASED)
    Year 4: underestimated by 3 million (amount by which they underestimated INCREASED)
    etc.

All we know is that the agency seriously underestimated what the GNP's would be five years later. We have no idea whether the SIZE of their error decreased, increased, or remained the same year to year, so choice (C) cannot be determined.

ah, I see the key word "for an example" now. Again, we can only make an inference from the passage. The paragraph does not state or give any numbers about the GNP, so we cannot know whether the amount increases or decreases.
