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：原文反复谈的就是盐的摄入会导致高血压，我想让这个观点不靠谱，我们来看看选项A说基因的原因导致了高血压增加的缺失，谈的和原文就不是一个事，干掉。B说这个吃高盐食物的人得了高血压，这个不能驳斥原文，像支持的，杀。C说生活在工业化国家吃低盐食物是可能的，原文没提这个事，杀。D说食物其他方面有变化，那就让盐这个方面的变化导致高血压的可能性变小了，留着。E说盐对人很重要，当人丢失大量盐分后会导致死亡，扯淡的选项！
