大全-B-2

大全-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.

请NN们分析一下思路？

我有些想法，求指教：

关键要理解“an assumption made in the argument”，
原文Argument是“Similar air-pollution rules should be imposed in other major cities”，所以assumption应该是加强“从伦敦推行到其他城市”，加强的方法：1、证明方法有效、有益（BDE） 2、其他地方和伦敦情况相近（C）
而A是加强“为什么在伦敦imposed strict air-pollution regulations on local industry，会取得效果”的assumption，而非针对Argument的assumption
