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. 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 salt
题目分析：这道题目问题所问比较准确，就是说人进城市吃高盐食物就得高血压这个事实不能证明是盐导致的高血压，因为A因为基因因素能解释缺乏高血压，奇怪，我得了高血压，怎么能是the lack of increase of blood pressure呢？杀。B说一生下来住在城市的人会得高血压，我得事实是这些人move进城市的，不是一出生就住在城市的，范围没关系，杀。C说在城市吃低盐食物是可能的，我的事实是这帮人就是吃高盐食物了，又跑题了。D说当这帮人进入城市之后饮食的其他方面也发生了变化，那就降低了盐引起高血压的可能性，留着。E说盐对人很重要，身体缺盐的时候会死亡，扯淡的选项。
