新东方补充材料逻辑第 59题：

59. 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 tht 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' hipothesis?

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

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

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

(D)Blood pressurs 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.

I chose D, but the answer is A. why??

Thanks for your time!

高血压 解释原因 因为多盐的饮食与适于少盐的基因起反映

削弱 1 他因 2 多盐的饮食与适于少盐的基因起反映 不会引起高血压

A说明盐多 而高血压少 属于2型的削弱

DBlood pressurs 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.

situated far inland from sources of sea salt and far south of Saharan salt mines.并不意味着盐少 是个混肴选项 所以错

Thanks for your kindest answer!

But as a matter of fact, the answer should CONFIRM the conclusion. It seems A is weakening the conclusion....

sissi_woo ,

sorry,  i agree with u . any nn can help? thanks.

sissi_woo

maybe the answer is wrong?

cranberry

the answer is right.

文章结论是：西方多盐的饮食和黑人对少盐环境的适应导致了西方化的黑人的高血压。

A 是说，黑人中吃盐多的在西方化后就没有高血压。支持了少盐和高血压的关系。
