大全-B-2

Test B
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.
显示正确答案是A,但是觉得应该是D
如果A取非,那么,结论必不成立,因为原regulations是针对local industry而起作用的,若其他地方的local industry不是主要污染源,那么,类似的regulations就无法起到有效作用。
