rostov Wrote:He doesn't make a generalization. He says "numerous books" and "usually the authors of such books". He never says all books. So that's why I think B is wrong. D is much better because those "numerous books" and "authors of such books" could be referring to just one particular culture as D says.
While I agree that there is no generalization made between the first and the second sentence as you pointed out, I do see some leap between the second and the third; suggesting something (single objective standard of politeness) based off of few authors didn't sound quite right. I thought (B) tried to get at this leap, by suggesting that if ALL books were to codify/classify standards either polite or rude then it is more reasonable to suggest the same thing. However, I do see many reasons why this also can problematic...So I was thinking that maybe by stimulus saying "THIS suggests that there is a single...." rather than "It must be that..." there is not much of a leap between the second and the third sentence...can anyone verify??
As for (D), I couldn't quite agree with bbridwell's explanation that (D) gets rid of MAIN REASON for saying "standards of politeness vary from culture to culture". You can still say that the standards vary by culture despite some authors writing about standards for one particular culture... To me, (D) rather seemed to attack the flow from "usually, the authors of such book codify/classify as rude/polite" to intermediary conclusion, "this suggests that there is single standard of politeness". After all, how can we say that there is a single standard (not culture specific but in general) if the authors were writing for one particular culture as (D) suggests...In addition, I perceive the "Clearly, the standards of politeness vary from culture to culture" part as a fact, a premise not an intermediary conclusion as I don't see how one can arrive at this from the suggestion that there is a single standard of politeness; they seem to contradict each other. Please correct me if I am wrong.
