102. Although migraine headaches are believed to be caused by food allergies, putting patients on diets that eliminate those foods to which the patients have been demonstrated to have allergic migraine reactions frequently does not stop headaches. Obviously, some other cause of migraine headaches besides food allergies much exist.
Which of the following, if true, would most weaken the conclusion above?
(A) Many common foods elicit an allergic response only after several days, making it very difficult to observe links between specific foods patients eat and headaches they develop.
(B) Food allergies affect many people who never develop the symptom of migraine headaches.
(C) Many patients report that the foods that cause them migraine headaches are among the foods that they most enjoy eating.
(D) Very few patients have allergic migraine reactions as children live migraine-free adult lives once they have eliminated from their diets foods to which they have been demonstrated to be allergic.
(E) Very rarely do food allergies cause patients to suffer a symptom more severe than that of migraine headaches. A
Pls help translate D.
What does " eliminate from A to B" mean?
请牛牛指教
我再顶
D的前半句莫名其妙，等待NN讲解：）
后半句不应该是eliminate from A to B，to是后面非限定性定语从句的前置介词，还原就是
they have eliminated from their diets foods which they have been demonstrated to be allergic to.
然后上面是一个小倒装，为的是让which来修饰foods，还原就是 they have eliminated foods from their diets.
我也不知道这么理解对不对：（ 不好意思。
Very few patients (who) have allergic migraine reactions as children live migraine-free ()lives(life+es) when adult, once they have eliminated from their diets foods ()which they have been demonstrated to be allergic (to).
第一个live：动词
第二个lives：life的复数。
问一个语法问题，who这样的引导词省略是否有点不正式呢？
原句应该是
Very few patients have allergic migraine reactions as children (AND THEN)live migraine-free adult lives once they have eliminated from their diets foods to which they have been demonstrated to be allergic.
