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
我选的E，虽然觉得D没有问题，但我想不明白E为什么错呀
E：题目说人们吃了高盐才会导致高血压，不能就认为盐就是高血压的罪魁祸首因为盐是身体必须的。
不能说高盐量不好就是盐的责任了吧？
感觉E没问题呢。。。感觉进入死路了
求NN解答
