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.

It should be between A and B, but A is too strong. so it is A.

(B) Air-pollution regulations on industry have a significant impact on the quality of the air.

I hope the negation test will help.

The author is saying that the air became cleaner thanks to the air-pollution regulations.

If air-pollution regulations do not have a significant impact on the quality of the air, there is no relationship between the quality of air and the regulation, and so it's of no use to impose such regulations.
