请教大全-B-2

这是从CD上当下来的一个叫GMAT&LSAT CR的文件里的一题

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.

答案是A.我选D

为什么选A呢? A否定后,多数城市空气污染不是由地方工业造成的. 防污染规范就不施于那些城市

削弱了argument.因为从题意知那规范是对地方工业的.In the years since the city of London imposed strict air-pollution regulations on local industry.

请指点一下

真不好意思, 携隐JJ.我真不知道它是不是叫大全,反正全是逻辑题.

文件使用说明下注Gem,j(应该是整理这个文件的NN),包括

GMAT TESTA~D,TESTI~III, TEST1~20;  LSAT TEST1~28,及01~02的3套题.

因为是原先下载的,东西太多,搞不清了.

这题是GMAT TEST B 的第2题.

sorry for this question. 我找到讨论了. 谢谢携隐JJ.
