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.

IMO..A..the assumption is too extreme and cannot be relevant with the argument facts.

"(A) In most major cities, air-pollution problems are caused almost entirely by local industry." The first statement " city of London imposed strict air-pollution regulations on local industry," suggest that local industry was cause of pollution in london which was brought under regulation and then the last line, "Similar air-pollution rules should be imposed in other major cities." suggests that the local industries are are the primary reason for air pollution in other cities too.

IMHO the answer should be D

Since the passages does not even remotely suggest that birds are desirable. On the lighter side extending it further the we can safely assume the birds do not cause air pollution.

IMO A...
There is no reference to local industry.

Pollution could be because of vehicles,etc.

I thought the answer was E. There is a reference to local industry right in the first sentence: "In the years since the city of London imposed strict air-pollution regulations on local industry..."

Since the regulations were imposed on local industry, then isn't an assumption that local industry is one of the main causes of air pollution?

Ya! I was incorrect...
But economist have explained it right (entirely is too extreme word), so should be A.

(D) An increase in the number of bird species in and around a city is desirable. -- I thought the argument was pertaining to reduciton of air pollution and a increase in brid population is only an indication that the regulating rules in London helped in reducing the air pollution.

So why should this be a valid assumption?

I read the arguments carefully, I agree A is bit too extreme which makes it a suitable candidate.
