Supported is more like an answer that is a valid inference or sounds like it pretty reasonably goes along with the paragraph. We're looking for something that starkly goes against the paragraph. Reversal negation refer to ideas that are tempting because we know it's an incorrect manipulation of a conditional logic rule. It's not a valid inference. But it's not that's not the same thing as contradicting a rule. Finally, some answers will be too weak to contradict, which is sort of like saying unopposed that they could still fit within the margins of the facts we were told.
