E.....because if something that is not harmful to environment is subject to controls, those controls would be more restrictive than necessary


OA:E

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
_________________

ARGUMENT
[prem] Most members favored uniform controls on fumes, whether or not damage could be attributed to any source;
[complete] In order to avoid excessive restrictive controls…
[asum] We must assume that these controls are for fumes that actually cause damage, because if this wasn't the case, then this would be seen as excessive.

A. this would not avoid excessive controls;
B. out scope;
C. irrelevant;
D. what about those fumes that reach the forest afterwards? out;

Answer (E): if controls are subject to all fumes, even those that do not cause damage, this would be seen as excessive.

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.
