大全-B-2(第二次求救啊!help!)

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.

为什么答案是A?谢谢大家

     My thoughts about the question are:   


     Impose strict air-pollution regulations on local industry --> bird species increase


     Therefore, no matter how serious the air-pollution caused by local industry, impose the law can increase the bird species. Instead, other cities should have the same air-pollution situation like London, as choice C states. So choice A is an unnecessary assumption.


It's my 2 cents, any imputs are welcome!!

对A取非:in most major cities, air-pollution problems are not caused almost entirely by local industry.
不是entirely, 但可以是partly。即使仅是partly caused by local industry, 采取排污限制措施仍然会对其它城市有利。所以对A取非不能得出相反结论,A不是原结论的assumption.

谢谢大家的帮忙,偶又看了一遍提,关键是吧assumption,support给混了;还有就是The increased sightings of bird species ——这局看走眼了。

many thanks to you all!
