[問題]問一題 CR1000的 TEST B 第二題..
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.
我在A跟D之間想了想,最後選 D
我知道 A 不是assumption, 因為London的AP沒提到是誰造成。
想不通的是 D, 我以為這個答案應該是 irrelevant
有人可以麻煩解釋一下 D 嗎?
ps.正確答案是A,其他都是假設,A不是
