Which of the following most logically completes the argument given?
32
People in isolated rain-forest communities tend to live on a largely vegetarian diet, and
they eat little salt. Few of them suffer from high blood pressure, and their blood pressure
does not tend to increase with age, as is common in industrialized countries. Such people
often do develop high blood pressure when they move to cities and adopt high-salt diets.
Though suggestive, these facts do not establish salt as the culprit in high blood pressure,
however, because ________.
A. genetic factors could account for the lack of increase of blood pressure with age
among such people
B. people eating high-salt diets and living from birth in cities in industrialized
societies generally have a tendency to have high blood pressure
C. it is possible to have a low-salt diet while living in a city in an industrialized
country
D. there are changes in other aspects of diet when such people move to the city
E. salt is a necessity for human life, and death can occur when the body loses too
much sal
MINE A
ANS D
请指教
题目没看清
谢谢
那C呢?时不时因为C只是说吃含盐少的食物, 但是因为文中已经说了从雨林里来人都不怎么吃盐,所以这个选项对他们没用，因为即使他们进了城还是不怎么吃盐,说明肯定是其他的物质导致他们血压升高的,是吗?

第一,劃黃線的部分文中似乎並無說明,文中只說明了搬到城市後adopt high-salt diets,常會得high blood pressure,.......第二,此篇為complete,最後劃線的地方接在because之後,因此形成"因果",C無法說明此因果,再看一次C:"it is possible to have a low-salt diet while living in a city in an industrialized
country".....當住在城市時,可不可能吃低塩飲食,無論結果"是或不是",都不能說明為什麼雨林的人搬到城市後為什麼會得high blood pressure............個人拙見,參考....
解释的很清楚，谢谢你，爱维兄!
还真是这么回事
