Hi Menken and Schlueter! Thanks so much for your great questions, which are related
Menken — you're correct that answer choice (D) is wrong because of what's in the sufficient vs. necessary conditions. The author of the stimulus concludes that confiscating a portion of burglars' wages is justified even if it is stealing. However, in answer choice (D), "justified" is in the sufficient condition. To make a conclusion about the practice being justified, we need a principle that has "justified" in the necessary condition. (Alternatively, a correct answer could have had "not justified" in the sufficient condition since, via the contrapositive, "justified" would be in the necessary condition).
Schlueter — building off of what I said above, the issue is that "justified" is in the sufficient condition. Even if the necessary condition in answer choice (D) is met, we cannot conclude anything about the sufficient condition. And what we want to conclude in the stimulus is what is in the sufficient condition: that the action is justified. With conditional statements, we can only make the following conclusions: if the sufficient condition is met, we can conclude that the necessary condition holds; or if the necessary condition is NOT met, we can conclude that the sufficient condition does NOT hold. We can never make a conclusion about the sufficient condition in a conditional statement. As such, answer choice (D) cannot be correct, since the necessary condition being met does not tell us whether the action is justified.
I hope this helps, and please let me know if you have any other questions!
