If you get it wrong review and do your best to understand why, dont get strung up over it. It is foundations. Put the effort to understand and youll eventually get it. Ps I got it wrong on both the intial answer and blind review, I chose B initially, in blind review i eliminated to A an C and then chose A. Both A and B are attractive trap answers because they are general but they are not the MOST correct answer supported by the passage. Additionally you have not review the lessons break down for sufficient and necessity to have a grasp, this was considered a harder question. Yet in grammar section I got questions that were considered extremely hard correct and ones that were easy wrong. Read clearly, dont worry about time, worry about grasping, remember the LSAT grades you on how many you get correct not incorrect, hope this gives hope to those who are still struggling with grasping concepts, dont give up.
