teddykim,
I completely agree that the stimulus involves a nested conditional, and that you've diagrammed it correctly. You even did the Unless Equation (here necessitated by the word "except") exactly correctly. If you want to focus on a digrammatic analysis of this stimulus, consider that a conditional is false if and only if the sufficient condition is true and the necessary false. Since we have a nested conditional here, the necessary condition is false if and only if ITS internal sufficient condition is true and its internal necessary condition false. Thus, we should absolutely be focusing on a situation where the government messes with adults for a reason other than to prevent negative effects on others. That would violate the necessary condition of the entire stimulus (the necessary condition which is itself a conditional). If multiple answers seemed to do that, but one of them left it open whether the "in order to" statement was true, then we could reject such an answer based on that. Since that issue does not arise among these five answer choices, we can instead focus entirely on the necessary! To some extent, we get "lucky" here, but I think this just reflects the principle that we should make as little effort as possible in getting to the correct answer. The necessary condition of the entire stimulus allows us to eliminate every answer except answer choice (E). Thus, that's all we need to use for this question.
