Which of the following most logically completes the argument given below?
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.

Such peopleoften do develop high blood pressure when they moveto cities and adopt high-salt diets. Though suggestive,these facts do not establish salt as the culprit in highblood 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 salt
C选项说得是 in a city in an industrialized country,请注意原文中的 as is common in industrialized countries. 所以,in a city in an industrialized country指的是热带雨林里的人,而不是搬到城市的人。如果C改成lz说的,搬到城市里的人 低盐分摄入还得高血压,理论上是可以的。。。不过这样的话,和原文的they move to cities and adopt high-salt diets不符吧
