The U.S. census is not perfect: thousands of Ame -Old Thread [#permalink] New post 28 Dec 2004, 12:24
The U.S. census is not perfect: thousands of Americans probably go uncounted. However, the basic statistical portrait of the nation painted by the census is accurate. Certainly some of the poor go uncounted, particularly the homeless; but some of the rich go uncounted as well, because they are often abroad or traveling between one residence and another.

Which of the following is an assumption on which the argument above depends?

(A) Both the rich and the poor have personal and economic reasons to avoid being counted by the census.
(B) All Americans may reasonably be classified as either poor or rich.
(C) The percentage of poor Americans uncounted by the census is close to the percentage of rich Americans uncounted.
(D) The number of homeless Americans is approximately equal to the number of rich Americans.
(E) The primary purpose of the census is to analyze the economic status of the American population.

Re: CR US census [#permalink] New post 24 Oct 2005, 15:32
Fact: US census doesn't count thousands of Americans.
Conclusion: Basic stat portrait of the nation painted by census is accurate.
Premise: Some poor are not counted, and some rich are not counted.

What's the assumption that connects the premise to the conclusion?

(A) Both the rich and the poor have personal and economic reasons to avoid being counted by the census.
Irrelevant

(B) All Americans may reasonably be classified as either poor or rich.
Plausible. Because if all middle class are counted, with non counted rich and poor then could census portrait be accurate?

(C) The percentage of poor Americans uncounted by the census is close to the percentage of rich Americans uncounted.
Also plausible. If the percentage is not the same then the portrait may not be accurate.

(D) The number of homeless Americans is approximately equal to the number of rich Americans.
It doesn't have to be. We are not concerned with absolute numbers here.

(E) The primary purpose of the census is to analyze the economic status of the American population.
Again plausible. If it is not to analyze the economic status then why does it matter if the unaccounted are rich or poor?

E is incorrect because even if cencus was to analyze other factors, say age, as long as C is true we could still argue that the census is accurate.
I am not very sure why C is better than B, though.

Well, it's 'C' & not 'B' because the conclusion,

" Basic stat portrait of the nation painted by census is accurate",

is correct only if,

The percentage of uncounted poor Americans is close to the percentage of uncounted rich Americans (this is 'C')

This is the only assumption that will balance the count, to keep the census accurate.

But again that argument holds if we assume that rich and poor are the two categories being counted! no??

I think we need both assumptions. :( Either one of them by itself will not be sufficient. I mean yes rich and poor may balance out but if they don't balance out with the middle part I wouldn't say it is accurate.

Then again if you get rid of the middle part and if you don't assume rich and poor balance out the census still can't be accurate.

I suppose you just pick the less of the devil for this question, which is C.

Because by reading the passage the key words are counted and uncounted. We must form an assumption here based on these keywords.

If you negate this assumption then the argument will not stand.

E sounds more like it to me.

"However, the basic statistical portrait of the nation painted by the census is accurate."

This followed by references only to rich and poor, suggests E.
