非G友带着绝望求GMAT逻辑大全-TEST 3-第19题的权威答案

zs_wu

题目如下


大全-3-19.        Black Americans are, on the whole, about twice as
likely as White Americans to develop high blood pressure. This
likelihood also holds for westernized Black Africans when compared to
White Africans.


Researchers have hypothesized that this predisposition in westernized
Blacks may reflect an interaction between western high-salt diets and
genes that adapted to an environmental scarcity of salt.


Which of the following statements about present-day, westernized Black
Africans, if true, would most tend to confirm the researchers’
hypothesis?


(A) The blood pressures of those descended from peoples situated
throughout their history in Senegal and Gambia, where salt was always
available, are low.


(B) The unusually high salt consumption in certain areas of Africa represents a serious health problem.


(C) Because of their blood pressure levels, most White Africans have markedly decreased their salt consumption.


(D) Blood pressures are low among the Yoruba, who, throughout their
history, have been situated far inland from sources of sea salt and far
south of Saharan salt mines.


(E) No significant differences in salt metabolism have been found
between those people who have had salt available throughout their
history and those who have not.

这道极具迷惑性的题目，在很多bbs都有讨论过，请贵bbs各位G友帮助我向我们学校的评卷老师证明这道题的答案是A，而不是D。

    


我找了好几天才找到这道题目的英语原版，这道题目出现在是逻辑大全test3第19题目，http://forum.**********.com/dispbbs.asp?

    


BoardID=24&ID=56630


也有人说是机考题目http://www.taisha.org/bbs/redirect.php?fid=6&tid=531739&goto=nextnewset


，这道题目还出现在这里http://www.indicareer.com/sample ... g-questions-15.html

    


我想知道这道题目的原出处（最好，应该是只能是Gmat官方出的题目），或者权威的解答，来证明答案为A。我准备把相关资料打印出来给评卷老师看，试图说服他改掉他的答案。

    


最后，我阐述求助的具体原因：我们学校（广东某综合性大学，具体名字不提了）有一个双学位入学考试，考察部分包括逻辑，而这道题目的中文译文
版本就是其中一题，可是评卷老师把D作为正确答案。。所以这里只能诉讼权威，希望找到权威答案，把他交给教务人员转交给评卷老师看。

这道题中文翻译版出现过在2001年国内mpa联考的逻辑样题里，所以说至少是7年前的题目，还能追踪到原始出处吗，是EST官方出过的考题吗？

gonghao

这题是A啊

难道样题写的答案是D？？

D看一眼就排出了。说的什么乱七八糟的都靠不上谱。

样题是A，只是我们评卷老师出题的时候是原搬不动把一份模拟试题http://www.52mba.com/sjhh_news_view.asp?d_id=2605&sort1=26&sort2=64抄过来，所以答案也是对于那份不知所谓的模拟试题的。

看了中文。太可笑了。海盐和盐矿不都是盐吗？哪个是缺盐的？

D的陈述说白了就是没意义。因为D的後半句的比较关系是没有作用的。除非比较的是缺盐和富盐的地区。
