7. Whenever a major airplane accident occurs, there is a dramatic increase in the number of airplane mishaps reported, a phenomenon that may last for as long as a few months after the accident. Airline officials assert that the publicity given the gruesomeness of major airplane accidents focuses media attention on the airline industry and the increase in the number of reported accidents is caused by an increase in the number of news sources covering airline accident, not by an increase in the number of accidents.

Which of the following, if true, would seriously weaken the assertions of the airline officials?

(A) The publicity surrounding airline accidents is largely limited to the country in which the crash occurred.

(B) Airline accidents tend to occur far more often during certain peak travel months.

(C) News organizations do not have any guidelines to help them decide how severe or how close an accident must be for it to receive coverage.

(D) Airplane accidents receive coverage by news sources only when the news sources find it advantageous to do so.

(E) Studies by government regulations show that the number of airplane flight miles remains relatively constant from month to month.

12. A newly discovered disease is thought to be caused by a certain bacterium. However, recently released data notes that the bacterium thrives in the presence of a certain virus, implying that it is actually the virus that causes the new disease.

Which of the following pieces of evidence would most support the data’s implication?

(A) In the absence of the virus, the disease has been observed to follow infection by the bacterium.

(B) The virus has been shown to aid the growth of bacterium, a process which often leads to the onset of the disease.

(C) The virus alone has been observed in many cases of the disease.

(D) In cases where the disease does not develop, infection by the bacterium is usually preceded by infection by the virus.

(E) Onset of the disease usually follows infection by both the virus and the bacterium.

Answer:c,我是认为virus-àbacterium thrive-ànew disease,所以选了b,请帮我解答一下

第7题应该是B，

因为原文说的是飞机事故实际上并没有媒体上说的那么多，之所以大家看到了那么多只是因为媒体太多的报道了这些事故

那作为削弱，当然是要找出原文逻辑上的弱点，假设实际上某几个月由于飞机飞行频率的增加，事故本身也就发生的很多的话，那媒体上的那些报道就不能说是因为媒体的原因，而实际上飞机事故就是很多了，对原文做出了一个很好的削弱

第2题也是选C的

因为原文中说了在发病时会同时出现两种咚咚，bacterium 和certain virus

那要怎么才能说明后面的那个才是罪魁祸首呢，只有C的条件，The virus alone has been observed in many cases of the disease

也就是说没有bacterium 也能发病

这不就正好应了原文的最后一句话that it is actually the virus that causes the new disease
