问题 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. Each of the following, if true, provides support to the argument EXCEPT:
选项 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 bronchial inhalers make the lungs more sensitive to irritation by airborne pollen.
D、By tem|X)rarily 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.
答案 A
解析 选项(A)是明显不能支持上述论述的选项。在其他条件不变的前提下，城市人口在过去10年中增加了一倍，也只能使死于哮喘病的人增加一倍，而不能使哮喘病的死亡率增加一倍，因此本题的正确选项为(A)。(B)、(C)、(D)和(E)选项经仔细分析后可发现它们都可以支持段落的论证。
