(B) any substance to be made subject to controls can actually cause environmental damage

(C) the countries favoring uniform controls are those generating the largest quantities of effluents

(D) all of any given pollutant that is to be controlled actually reaches the North Sea at present

(E) environmental damage already inflicted on the North Sea is reversible

A conference was held to address environmental threats to the North Sea. Even if you don't know the meaning of the word "effluent", from the context you should be able to infer that it is some type of waste that could potentially harm the sea.

The countries participating in the conference favor uniform controls (or restrictions) on the quality of those effluents. The issue is that they aren't sure which sources of effluents actually cause environmental damage. As a result, they might end up restricting sources that DON'T actually cause any environmental damage. Such a restriction would be excessive, since it would involve controlling substances that are not actually threats to the sea. If they could somehow only control the HARMFUL effluents, then the controls could not be considered excessively restrictive.

With that in mind, in order to avoid excessively restrictive controls, it must be shown that...

Quote:
(A) any uniform controls that are adopted are likely to be implemented without delay

We aren't concerned with the timing of the controls. Rather, we care about the controls' being excessively restrictive. The schedule of the controls has nothing to do with how restrictive they are, so (A) can be eliminated.

Quote:
(B) any substance to be made subject to controls can actually cause environmental damage

As described above, controls on substances that are not actually harmful would be considered excessive. If we can show that any substance subject to the controls actually CAN cause environmental damage, then we would show that we are not restricting harmless substances. This would eliminate the concern about excessively restrictive controls, so choice (B) looks pretty good.

Quote:
(C) the countries favoring uniform controls are those generating the largest quantities of effluents

The countries generating the largest quantities of effluents may NOT favor the controls. So what? Whether those countries like the controls doesn't tell us whether the controls restrict harmless substances. Thus, regardless of whether this statement is true, the controls may or may not be excessively restrictive. Eliminate (C).

Quote:
(D) all of any given pollutant that is to be controlled actually reaches the North Sea at present

The word "all" should be a red flag. What if only MOST or SOME of a given pollutant actually reaches the North Sea? Would controlling that substance be excessively restrictive just because SOME of it doesn't reach the North Sea? Of course not. Furthermore, if an effluent is known to be an environmental threat, it might make sense to implement controls to ensure it doesn't harm the North Sea in the future. Eliminate (D).

Quote:
(E) environmental damage already inflicted on the North Sea is reversible

Even if the present damage is irreversible, we would still want to limit FURTHER damage by implementing the controls. Controls on harmful substances would not be excessively restrictive even if they only succeed in keeping the damage at the current level. Choice (E) is thus irrelevant and can be eliminated.

(B) is the best answer.

What must, of course, be shown, in order to avoid excessively restrictive controls, is that _______.

If we can show that the controls are not excessively restrictive then we can avoid the blame of being called 'excessively restrictive controls'. It is possible only if the effluents that will be covered in the control actually does harm to environment.

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
Delay in the application of control is out of scope

(B) any substance to be made subject to controls can actually cause environmental damage
Correct. If the substabce doesn't cause any harm then excersising control is not good, invalidating the argument

(C) the countries favoring uniform controls are those generating the largest quantities of effluents
Countries are out of scope

(D) all of any given pollutant that is to be controlled actually reaches the North Sea at present
If the pollutabt can reach after a few days/years then it will be an issue.

(E) environmental damage already inflicted on the North Sea is reversible
If the damage is reversible then the whole point of controlling the affluents is pointless

i think It is B. It is saying saying that all the effluents can cause damage and that gives a solid reason to avoid restrictive control.D says all the pollutants reach North sea but it fails to mention why all the effluents (not mentioned in the argument that all effluents are pollutants) are to be controlled.

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 - Irrelevent

(B) any substance to be made subject to controls can actually cause environmental damage - Correct

(C) the countries favoring uniform controls are those generating the largest quantities of effluents - Irrelevent

(D) all of any given pollutant that is to be controlled actually reaches the North Sea at present
- does not matter if 'all' of the pollutant reaches --even some can cause damage (depending on how much was released)

(E) environmental damage already inflicted on the North Sea is reversible - Irrelevent
