So-called environmentalists have argued that the proposed Golden Lake Development would interfere with bird-migration patterns. However, the fact that these same people have raised environmental objections to virtually every development proposal brought before the council in recent years indicates that their expressed concern for bird-migration patterns is nothing but a mask for their antidevelopment, antiprogress agenda. Their claim, therefore, should be dismissed without further consideration.
Which one of the following questionable argumentative techniques is employed in the passage?
(A) taking the failure of a given argument to establish its conclusion as the basis for claiming that the view expressed by that conclusion is false
Well there is no indication the environmentalists claim is false. So their argument does not fail based on the information given. A is out(B) rejecting the conclusion of an argument on the basis of a claim about the motives of those advancing the argument
The conclusion is that the development would interfere with bird-migration patterns. This is rejected based on the underlying motives of the environmentalists thus those advancing the argument. Let's keep B(C) using a few exceptional cases as the basis for a claim about what is true in general
Sounds good as well, but we do not know whether the other claims are justified or just based or not. He argues with the underlying motive of environmentalists rather than with individual cases. C is out(D) misrepresenting evidence that supports the position the argument is intended to refute
There is actually no real evidence so D is out as well(E) assuming that what is true of a group as a whole is necessarily true of each member of that group
It is explicitly stated that the concerns were raised by the same people. E is out as well
