In this principle question we need to justify the argument contained in the stimulus with a general rule in the answer choices that will bridge a gap between the evidence and the conclusion in the argument.
The evidence is that the vote of any individual is much more likely to determine organizational policy by influencing the election of an officer than by influencing the result of a direct vote.
The conclusion that is reached is that the organization should make decisions about important issues by the election of an officer rather than direct vote.
A principle that says that an organization should make decisions in a way that will maximize an individual's influence would work - best expressed in answer choice (E).
(A) is out of scope. The issue is not about one person's vote weighing more than any other.
(B) is out of scope. The issue is not evaluating outcomes, but rather selecting the mode of making decisions.
(C) supports the conclusion but does not rely on the evidence and so cannot be said to be a principle that could be applicable.
(D) is out of scope. Again the issue is not which decisions are right or wrong, but rather how should those decisions be made.
(E) bridges the gap between the evidence and the conclusion and is the correct answer. If maximizing the individual's power is the goal, and we know that the individual is more likely to have an impact on the election of an officer, then the conclusion follows that the organization should make decisions by election of an officer.
