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.

C for me.

D. Lets say if no. of homeless americans is 100 and 10 dont get counted. If no. of rich ameircans is 100 and 5 dont get counted, then the census is not accurate.

On the contrary the cesus will be accurate if the percentage of homeless not counted ~ percentage of homless not counted.

"C" for me.
Only when "C" is assumed, the census is balanced.

Will go with C.

The problem with D is that it talks about the number only not the number of rich or poor who go uncounted.

If the number of poor (percentage) who go uncounted is more than the number of rich(percentage) , then the author's argument falls flat.

I've gotta go with E here. The 'argument' in the passage is that 'the basic statistical portrait of the nation painted by the census is accurate.'

A just doesn't matter to the argument. B, doesn't really matter (I'll explain in next part).

C doesn't really matter to the argument because it doesn't matter if the uncounted Americans are rich or poor (as in B), or if the number of rich and poor are equal. D also doesn't matter for the same reason.

By my reading, the only thing that matters is that while thousands of Americans go uncounted (be they rich, poor, middleclass or homeless), the statistical portrait of the nation is still correct.

E is the only answer that captures the argument of the passage. That's my answer and I'm sticking to it.

The OA is C. Apparantly percentage is what that counts for census.

The argument assumes that there are only poor and rich people.

B i think. If the group cannot be classified into rich and poor, then the fact that rich and poor travel maintain a statistical balance is incomplete evidence for the claim that statistical balance is maintained.

Yes, A is too broad. Had it read "some of the..." then it could have been a plausible assumption.

Bagging (B) here.

Go with C.

The article insists that two errors in the rich and the poor should be offset by each other.
It will be the case only when the errors have the same proportion in their group.

Will go with C.

The conclusion is that the census is fairly accurate even when it doesnot count many homeless since the census also mis many rich people.

For this conclusion to be true we have to assume that the percentage of homeless people not counted is equal to the percentage of rich people uncounted.

for example:
There are 100 homeless people and 20 rich people.
But the 50 homeless go uncounted whereas only 2 rich people go uncounted.
