Questions 78-79
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.
79. Which one of the following is an assumption on which the argument depends?
A. Urban pollution has not doubled in the past decade.
B. Doctors and patients generally ignore the role of allergies in asthma.
C. Bronchial inhalers are unsafe, even when used according to the recommended instructions.
D. The use of bronchial inhalers aggravates other diseases that frequently occur among asthma sufferers and that often lead to fatal outcomes even when the asthma itself does not.
E. Increased urban pollution, improved recording of asthma deaths, and the used of asthma deaths, and the use of bronchial inhalers are the only possible explanations of the increased death rate due to asthma.
参考答案:E
思路:不是解释1和2,就是解释3。隐含了1,2,3外没用其他解释的理由。
A. 支持。
B. 无关。中心是role的问题。
C. 可以算无关,也可以算削弱。
D. 加强
取非,除了1,2,3解释还有其他解释。典型的他因削弱,符合ETS 假设定义。
问题是原文中没有提到E中的and the used of asthma deaths, 我选D。
根据大全LSAT - 2- II-23,THIS IS A TYPO,ORIGINAL CHOICE SHOULD BE AS FOLLOWS:
(E) Increased urban pollution, improved recording of asthma deaths, and the use of bronchial inhalers are the only possible explanations of the increased death rate due to asthma.
THAT EXPLAINS EVERYTHING!!
我觉得这道题非常诡异。前面的78题说的结论明明就是说只有解释3是正确的,因为它把证明解释1的给否定了。
为什么在79题里面就说结论是:不是解释1和2,就是解释3了呢???
这两个意思完全不一样啊 ??????
同困惑!!
谁能讲讲???
我一开始也是选的D,但是后来我发现原文中说one must instead conclude that ……,也就是说文中的意思是:bronchial inhalers必须作为一个替代的结论,它强调必须这个意思,如果是D,它不是必须的,因为还有可能有其他的解释,而E决定了你必须是bronchial inhalers,因为前面两个已经被否定了
