Competition Mode Question

Which of the following, best completes the passage below?

At last month's symposium on the increasing air pollution affecting the Beaumont forest, most participating members favored uniform controls on the quality of exhaust fumes, whether of not specific environmental damage could be attributed to a particular source of fumes. What must, of course, be shown, in order to avoid excessively restrictive controls, is that __________ .

A. any uniform controls that are adopted are likely to be implemented without delay
B. environmental damage already inflicted on the Beaumont forest is reversible
C. the members favoring uniform controls are those representing bodies that generate the largest quantities of exhaust fumes
D. all of any given pollutant that is to be controlled actually reaches Beaumont forest at present
E. any substance to be made subject to controls can actually cause environmental damage
_________________

A. any uniform controls that are adopted are likely to be implemented without delay
even if the controls are implemented with a "day" delay then the result is still possible


B. environmental damage already inflicted on the Beaumont forest is reversible
the promt is not concerned with the reversal of the damage but rather a control on the increasing pollution,
therefore B is wrong.

C. the members favouring uniform controls are those representing bodies that generate the largest quantities of exhaust fumes
even if they do not represent, it doesn't affect the argument as the action taken for controlling the pollution is more important than further information about the members.

D. all of any given pollutant that is to be controlled actually reaches Beaumont forest at present
even if some pollutant reaches the forest it sill affects the forest, therefore D is wrong

E. any substance to be made subject to controls can actually cause environmental damage
E seems to be the correct answer

Official Explanation

Correct Answer: E

The best answer is E. If a subject that causes no environmental damage were subject to controls, those controls would be more restrictive than necessary.
