Despite improvements in treatment for asthma, the death rate from this disease has doubled during the past decade from its previous rate. Two possible explanations for this increase have been offered. First, the recording of deaths due to asthma has become more widespread and accurate in the past decade than it had been previously. Second, there has been an increase in urban pollution. However, since the rate of deaths due to asthma has increased dramatically even in cities with long-standing, comprehensive medical records and with little or no urban pollution, one must instead conclude that the cause of increased deaths is the use of bronchial inhalers by asthma sufferers to relieve their symptoms.
78. Each of the following, if true, provides support to the argument EXCEPT:
(A) Urban populations have doubled in the past decade.
(B) Records of asthma deaths are as accurate for the past twenty years as for the past ten years.
(C) Evidence suggests that inhalers make the lungs more sensitive to irritation by airborne pollen.
(D) By temporarily relieving the symptoms of asthma, inhalers encourage sufferers to avoid more beneficial measures.
(E) Ten years ago bronchial inhalers were not available as an asthma treatment.

读出相关性即可.
首先看原文.原文说的是：甭管治疗a的方法牛逼了,a的死亡率还是增加了,从上个10年到现在.这种死亡率的增加有两个可能的解释.一是对a的死亡记载比以前记载的更详细广泛了；二是城市污染严重了.但是因为即使在有着全面长期的医疗记载以及城市只有很少甚至没有受到污染时,a的死亡率也迅速增长了,因此大家普遍认为此时a的死亡增长是由于a的患者用了b i这么一个东西去缓解他们的症状.
应该可以读成这样吧?
再看选项：
A.过去10年城市的人口double了.
B.a的致死的记载在20年前是和过去的10年同样准确的.
C.有证据显示i这个东西让肺更容易被空气传播的花粉刺激.
D.i这个东西除了暂时缓a解症状外就没其他好处了.
E.10年前b i这个东西并不用于a的治疗.
选项应该也可以读成这样吧?
题目问的是except,原文说了三件事,过去十年a致死率翻倍有两个原因,一是记载比以前全面了,二是城市污染了,但是有些地方一二不成立时a死亡率也涨了,所以这时认为是b i导致的.
此时明显A是无关选项.A说的是人口数量在过去10年涨没涨,显然不能对题目中的argument提供任何方面上的支持,纯属玩儿蛋选项.
