标题: 大全 TEST B-2

2.     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.



答案是A。可是我觉得D也对,都有点模棱两可。哪位NN指点下迷津?叩谢!

将D取非-城市中鸟的种类的增加是不令人满意的。那么simliar air polluting rule 就不必施加到其他城市上。削弱结论.因此D为假设。

almost entirely 是错误的关键。
