22. In 1992, a major newspaper circulated throughout North American paid its reporters an average salary paid by its principle competitors to their reporters. An executive of the newspaper argued that this practice was justified, since any shortfall that might exist in the reporters’ salaries is fully compensated by the valuable training they receive through their assignments.

Which one of the following, if true about the newspaper in 1992, most seriously undermines the justification offered by the executive?

A.    Senior reporters at the newspaper earned as much as reporters of similar stature who worked for the newspaper’s principle competitors.
B.    Most of the newspaper’s reporters had worked there for more than ten years.
C.    The circulation of the newspaper had recently reached a plateau, after it had increased steadily throughout the 1980s.
D.    The union that represented reporters at the newspaper was different from the union that represented reporters at the newspaper’s competitors.
E.    The newspaper was widely read throughout continental Europe and Great Britain as well as North America.

我的理解是一个城市是希望（自己城市）鸟类的数量增加的，因为如果不是的话，那自然不需要去限制污染了

shunwen

(D) An increase in the number of bird species in and around a city is desirable.这个D选项到底说的是什么意思

camelo777

A的问题是，A可以是一个假设，但不是绝对的，你不能说所有城市的污染都一定是工业污染对不对，所以A不是必须的

shunwen

but the first sentence is regulations on local industry.so I think the A in right.

首先就如LS所说，A不是一个必须的assumption，题目只是说限制了污染，所以鸟的数量上升，没规定一定是工业的污染
而E选项在另一方面是必须的，The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.
E选项消除了一个可能，那就是原文中说的鸟的increase可能是暂时的，也许正好这个时候有一大批鸟飞了过来，可能呆两天就走了，那就不能说明这个限制污染是有效果的。 E取非削弱，所以是一个必须的假设

E is definitely an assumption. Otherwise, one of the premise is wrong.

A, on the other hand is, not necessary. There are many causes of air polution: exhaust gas from cars, local industry, weather patterns, etc. In the case of argument, whether the air pollution is caused entirely by the local industry or not, the author still thinks more strict regulations would help.

In the years since the city of London imposed strict air-pollution regulations on local industry, the number of bird species seen in and around London has increased dramatically. Similar air-pollution rules should be imposed in other major cities.
Each of the following is an assumption made in the argument above EXCEPT:
(A) In most major cities, air-pollution problems are caused almost entirely by local industry.
(B) Air-pollution regulations on industry have a significant impact on the quality of the air.
(C) The air-pollution problems of other major cities are basically similar to those once suffered by London.
(D) An increase in the number of bird species in and around a city is desirable.
(E) The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.
这题怎么会选a呢？我觉得应该是e

谢谢。我看明白了
