Since the passage of the stateâ€™s Clean Air Act ten years ago, the level of industrial pollutants in the air has fallen by an average of 18 percent. This suggests that the restrictions on industry embodied in the act have worked effectively. However, during the same period the state has also suffered through a period of economic decline. The number of businesses in the state has fallen by 10 percent, and the number of workers employed has fallen by 12 percent. It is probable that the business decline, rather than the regulations in the act, is responsible for at least half of the decline in the pollution.

Which of the following, if true, would most seriously weaken the conclusion drawn in the passage above?
(A) During the last ten years, economic conditions in the nation as a whole have been worse than those within the state.
(B) Amendments to the Clean Air Act that were enacted six years ago have substantially strengthened its restrictions on industrial air pollution.
(C) Of the businesses that ceased operating in the state during the last ten years, only 5 percent were engaged in air-polluting industries.
(D) Several large corporations left the state during the last ten years partly in order to avoid compliance with the Clean Air Act.
(E) Due to its small budget, the state office charged with enforcement of the Clean Air Act has prosecuted only two violators of the law since its passage.

Clear winner C.

The author is concluding that the industrial decline over the last decade, may be responsible for the reduced pollution levels rather than the Clean Air Act.

If the number of industries that left town after the decline only contributed o 5 % of the pollution and the pollution decreased more than that, then the Clean air act might have soem hand in it.

the most fit solution for this question is A for the followiong reasons.....if B true this solution would address only to the first part of the passage and would mean less air polluted but does not help us to weaken the argumentation that states the partial responsability of industrial decline on air pollution,
C noes not help to weaken the argumentneither because that 5% of industries could have made up more than the 50% weighting a lot,... so is out
D uhm out strenghten the argument support the fact that less air polluted is is consequence of less companies
E out low risk to be charged strenghten argumentation

the point is that the 5% could be the representing the main polluter so this question could support second part of argumentation then is out
