I feel that B in Census question would have some weightage if option C were not there..

Must the author absolutely assume that all people can be classified as either rich or poor in order to reach this conclusion?

That's the standard on an assumption question - not could the author believe this, but MUST the author believe this to reach the conclusion. What do you think, in this case?

Perfect!!, thanks stacey, for pointing this out..
i got it now..

Stacey there is nothing wrong with the explanation in 19th question, even I got the same answer as C but the problem is that what you took as the premise and the conclusion, I totally took or identified the opposite.


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.

I took this as the Conclusion because of the word Certainly. Even when you read the sentence as the above sentence as the conclusion, the overall argument becomes logical. Please rectify if I am wrong. But the answer I get it as C as well.
