ff-78

  

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.


为何选a不选c呢

题目中已经说明了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,就是说,即使没什么环境污染,患者人数也增多,你就不要考虑环境问题了.


C是解释那个inhaler怎么干坏事的.即使污染没增加,它使肺更容易受影响,也会增加肺病概率

看清題目問的是什麼﹕下列哪一個不支持上面的文章。C說 inhalers make the lungs

more sensitive to irritation by airborne pollen.顯然是支持﹕the cause of

increased deaths is the use of bronchial inhalers

A說 Urban populations have doubled in the past decade是不支持.文章結論﹐

有可能人口增加了﹐發病綠也增加
