6 In the workplace, influenza is typically spread by
infected individuals to others with whom they work
in close quarters. A new medication that suppresses
the symptoms of influenza therefore will actually
increase the number of influenza cases, because this
medication will allow people who would otherwise be
home in bed to return to work while infected.
Which of the following, if true, most seriously chal-
lenges the prediction？
(A) Coughing, a symptom of influenza that the new
medication suppresses, is a primary mechanism
in the spread of this illness.
(B) Some medications that are used to suppress
symptoms of influenza are also used by many
people to treat symptoms that are caused not
by influenza but by other illnesses.
(C) Many workers who now remain at home when
infected with influenza do so because the
symptoms of influenza prevent them from per-
forming their jobs effectively.
(D) Most adults who are immunized against influ-
enza in order to avoid being infected are over
65 years old and retired and thus do not work
outside the home.
(E) Symptoms of an illness are often the body's
means of curing itself of the illness, and there-
fore suppression of symptoms can prolong the
illness that causes them.
我来试着解释下。题目的意思是I这个病一般是由感染的人传染给周围的人。现在有一种新型的针对I这一病的病症的疗法。the argument is 这种新型疗法会使得感染率更高。因为它使得I病的症状消失了（但是这些人仍然是属于感染的），他们现在去办公室工作的话让然会把疾病传播给其他人。题目问的是哪个答案能够challenge the prediction? 读到这里脑子里预想的一个答案就该是和“症状”和“传染”有关。选项A， 这种新疗法可以遏制coughing症状，而这一症状是I传播的主要机制。 这就直接challenge了句子中的prediction。 既然新的疗法能够把I传播的主要机制给遏制了，那么那些受感染的人到了办公室就不会传播疾病了。This one is perfect。 B， bullshit，说的什么和什么啊。只是说了一下乱七八糟的“事实”而已。和题目完全不相关。C is tempting。因为出现了“symptom.”但是这个选项是strengthen了题目中的prediction。既然被感染的人因为症状而工作效率低下，从而不去办公室工作，那么新的疗法解决了这些症状，他们就能工作的有效率，就会回到办公室工作。那么这些只是没了症状的感染人仍然会把病传播给其他人。所以C选项也不对。 E选项也是加强了题目中的prediction，所以也不能选。最后看D选项。。。我想不出楼主为什么选这个选项……我觉得和题目完全没有关系。作者: logically 时间: 2014-7-6 13:48:39
