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。
