大全-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.(A)



(E) The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.


难道A) 不是个assumption吗, 怎么是except??

我认为可以在A或E中选。A:almost entirely 太强,这可能不是作者所假设的。E:可以说 increased sightings of bird species in and around London 足以说明空气质量的改善,不需要假设:只有the number of species of birds actually increased, 才说明空气质量改善了。鉴于此,我认为选 E 更好。
