Hello! I got stuck on this question, so I looked at both the written explanation under the correct answer and then went to the video. The Written Explanation explains that the argument in question is invalid due to insufficiently overlapping conditionals, whereas the video infers that the conditionals need interpretation in a way that fits the argument. Both explanations (due to seeing the answer in foresight) perfectly interpret the correct option to fit their analysis of the questioned argument. In my opinion, the videos analysis fits when looking at the question, but then the written explanation looks at the correct answer option with a confusion that I shared. The result is leaving me split as to how to go about questions with greater confidence when in a time crunch, as is the point of this course. How should I look at questions where interpretations are argued by LSATMax itself, especially when there is no time to have my own mental debate between perspectives? I would very much love some help! Thank you
