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.

I found this one tough and got wrong after spending a long time on its analysis.

Hey you are posting some good CR questions: What is your source?

Most of the answer choices support one or the other (unhealthy diet or the genetics). None seem to be supporting both.

My best guess will be between A and D. POE A

B. out of scope
C. the passage is concerned with talking about westernized africans.
D. says salt not very accessible since the Yoruba lived inland. However, they could still have transported salt from the coast. Hence MAYBE case so I will discount this.
E. if this is true then it weakens the researches argument since it impleis that genes did not adapt.

I still doint get why (A) ?.Moreover (A) takls about low blood pressure

I also go with an A.

Reason is :

B) The unusually high salt consumption in certain areas of Africa represents a serious health problem. ( Out of scope)
(C) Because of their blood pressure levels, most White Africans have markedly decreased their salt consumption. ( Weakens )
(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. ( Weakens)
(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. ( Does not strengthen)

The only option that is left is A , and hence the best.

Hi,

I apologize that I do not have a better explanation for you. POE was the only way I got to it. I hope there are some others who can shed light on this CR.

I don't get why it can't be D though.

Because the hypothesis from the researchers is saying that they are NOT used to salt and develop high blood pressure because of high salt diets which is what D is saying.
