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.

我查了以前的帖子好多都是讨论D项的。。。可是我对c项很不解啊，解析说c项可以算无关也可以算削弱 可是c项怎么削弱了呢 实在是很难理解啊。。。


94. When 100 people who have not used cocaine are tested forcocaine use, on average only 5 will test positive. By contrast, of every 100people who have used cocaine 99 will test positive. Thus, when a randomlychosen group of people is tested for cocaine use, the vast people is tested forcocaine use, the vast majority of those who test positive will be people whohave used cocaine.
A reasoning error in the argument is that the argument

A.      attempts to infer a valuejudgment from purely factual premises.   
B.       attributes to every member of the population the properties of the average member of the population
C.       fails to take into account whatproportion of the population have used cocaine
D.      ignores the fact that somecocaine users do not test positive
E.       advocates testing people forcocaine use when there is no reason to suspect that they have used cocaine
这题我只是想问B项翻成中文是什么啊。。。。读不懂啊。。。。

试着答一下，94 B. attributes to every member ofthe population the

properties of the average member of the population 是说用均值划给了每个

个例， 比如说一组数平均是3，不等于每个数都是3，而B的意思就是将组里的平

均数赋给了每个值。

等NN继续解答。

还是。。。不是。。。很明白。。。。

我试着说下看对不对哈，
第一题：Ｃ选项是前半部分无关，后半部分削弱的。
unsafe 并没有表明会致死，所以无关。而后半部分确实是在削弱。
所以你看到的解析可能是在说明这个吧。

79题选a,c选项unsafe不等于increased deaths，我觉得c无关，不能削弱
94题把组合中平均水平的特性赋予给了组合中的每一个人，这个在中国最明显了。经常说人均住房面积30多平米，可是大部分人都没有房子，一少部分人有很多很多房子，房叔，房妹满天飞，说的就是这个题。一个人有5套房子，一个人没有房子，平均了一下每个人2.5套房子，说随便抽个人，这个人有2.5套房子。
