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.






7 Editorial：
Critics of nuclear power complain about the allegedly
serious harm that might result from continued operation
of existing nuclear power plants. But such concerns do
not justify closing these plants；after all, their operation
has caused no more harm than that caused by pollution
generated by coal-and oil-burning power plants, the
most important other sources of energy.
Which of the following is an assumption on which the
argument depends？
(A) Existing nuclear power plants should be closed only
if it can be conclusively demonstrated that their
continued operation is likely to cause harm more
serious than the harm their operation has already
caused.
(B) Closing existing nuclear power plants would require
greatly increased reliance on coal-and oil-burning
power plants.
(C) The harm that has resulted from operation of
existing coal-and oil-burning power plants has
been significant.
(D) The harm that a nuclear power plant is likely to
cause as it continues to operate can be reliably
predicted from the past history of nuclear power
plants.
(E) The only harm that has resulted from operation of
existing coal-and oil-burning power plants has
resulted from the pollution generated by these
plants.


答案分别为A,D。但是本人认为第6题的A选项好像没啥作用啊，没有challenge原文的idea，觉得选C，另外第7题，个人觉得B也说得通啊，主要后面有一个the most important  other sources of energy。不知各位怎么看，望指教，谢谢！

第6题真心不解
第7题 注意题目问"assumption"而不是问你哪个论据可以支持文中的论点 B选项的论据 跟题目的reasoning无关 尽管能够支持论点
D选项 如果不能非常predictable 那么它的risk就会很大 那么文中的论点就被削弱了
希望能帮到你

A: Coughing = influenza symptom
medication suppresses influenza symptom
Together we have: medication suppresses coughing

since coughing primary mechanism in illness spread
therefore, no coughing, much less illness spread
therefore, medication -> suppress coughing ->suppress illness spread ->the number of influenza cases falls

可是那位同学的原文是压制了症状之后增多了感冒的传播而不是减少。。。有点逻辑问题啊，如果A，压制了打喷嚏这个传播途径，为什么会感冒的人变多呢？？
