HideShow timer Statistics

Rumored declines in automobile-industry revenues are exaggerated. It is true that automobile manufactures’ share of the industry’s revenues fell from 65 percent two years ago to 50 percent today, but over the same period suppliers of automobile parts had their share increase from 15 percent to 20 percent and service companies (for example, distributors, dealers, and repairers) had their share increase from 20 percent to 30 percent.

Which one of the following best indicates why the statistics given above provide by themselves no evidence for the conclusion they are intended to support?

(A) The possibility is left open that the statistics for manufactures’ share of revenues come from a different source than the other statistics.
(B) No matter what changes the automobile industry’s overall revenues undergo, the total of all shares of these revenues must be 100 percent.
(C) No explanation is given for why the revenue shares of different sectors of the industry changed.
(D) Manufactures and parts companies depend for their revenue on dealers’ success in selling cars.
(E) Revenues are an important factor but are not the only factor in determining profits.

I would go with C.
The stem says that manufacturers' share of revenue is decreased while dealers' increased. it is negative correlation, which is very rarely seen in between those two sectors. Overal, no reasoning is give to support the rumored decline. Probably, new entrants in manufacturing have started sharing the sector revenue. Thus ones like Ford lost their revenue to Japanese ones while dealers started upping by diversifying their portfolios with new entrants' cars. But no evidence give to support that makes the statistics weak.

To show that there is decrease in the total revenue of the automobile industry, data to be given supporting the rumored decline. But the premises are showing the percentages of different market segments of the automobile industry. From these percentages we cannot make out whether there is a decline in the revenue. B-correctly states that.

hence the answer B!

The source of this Question is PowerScore CR Bible, pg 273. Moderator:please tag.

Knowing total market share is 100%, no matter what happen, direct you to B only.

the question is tough, but POE helps to choose B.
C,D,E are OFS.
A is wrong b/c the argument never mentions any details or information about the sources.
B looks strange, but B is logical. B tells that other parts must have declined shares.

Question stem says :
Conclusion : Rumored declines in automobile-industry revenues are exaggerated.
Premise : It is true that automobile manufactures’ share of the industry’s revenues fell from 65 percent two years ago to 50 percent today, but over the same period suppliers of automobile parts had their share increase from 15 percent to 20 percent and service companies (for example, distributors, dealers, and repairers) had their share increase from 20 percent to 30 percent.

So, we can see here that automobile manufactures' share has decreased and suppliers of automobile parts & service companies has increased.
Overall initially 65+15+20 = 100 %
Finally 50+20+30 = 100%

So, We are comparing only among automobiles manufacturers, suppliers and service companies, but this comparison doesn't reflect the share of revenue of automobile industry as a whole with respect to the other industries and the total volume of revenue.

(A) The possibility is left open that the statistics for manufactures’ share of revenues come from a different source than the other statistics.
It comes from different sources will not matter much as all sources are reliable unless stated.

(B) No matter what changes the automobile industry’s overall revenues undergo, the total of all shares of these revenues must be 100 percent.
This is talking correctly, the total of all share will always be 100% irrespective of automobile industry's overall revenues.

(C) No explanation is given for why the revenue shares of different sectors of the industry changed.
Doesn't matter as it is not giving the overall picture of automobile industry with respect to other industries in the market.

(D) Manufactures and parts companies depend for their revenue on dealers’ success in selling cars.
This if true will actually show a flaw in the argument. But the question is not asking for such thing.

(E) Revenues are an important factor but are not the only factor in determining profits.
out of scope. Here the stem talks about revenues and we should stick to it.
