Pre-thinking Betty believes that because her opponent opposes the rule she does not represent the high moral standards of Wilderness Scouts. Betty's argument is flawed as she assumes that the opposition to the rule is same as forbidding it.
A. Some Wilderness Scouts also oppose the loyalty pledge rule.We have to dispute the reasoning of Betty. The information presented in the option does not provide any information so as to indicate that Betty is incorrect in her reasoning.
B. Loyalty is only one of many virtues espoused by the Wilderness Scouts.This statement to some extent support Betty's argument. Hence it is the opposite to what we are looking for.
C. The opponent's position on the loyalty pledge rule may be atypical of her positions in general.This statement indicates that the opponent's position on the loyalty pledge may not represent her position in general. However, this doesn't provide us information if the opponent actually believes in the pledge or forbids it.
D. Refusing to require an activity like the loyalty pledge is not the same thing as forbidding it.This option is inline with Betty's argument and helps identify the flaw in Betty's argument. Betty's assumption that her opponent failed to represent the high moral standards of the Wilderness Scouts was based on the stand her opponent had taken on the activity. The option provides that information that just because her opponent refuses to require an activity doesn't mean the opponent forbids it.
E. Opposing loyalty to an organization does not necessarily mean that one is disloyal to that organization.This is an distortion, the point of discussion is with reference to the loyalty pledge. Betty's opponent is not opposing loyalty to the organization.
