An Alternative way to crack the question.

Hi comrades. For those of us who took the first sentence "if" as a sufficient condition, it is, strictly speaking, not wrong, and there is still a way to solve the question this way. I'm here to discuss with you this alternative way: When we first read the question stem, it was very easy for us to categorize the "if" sentence as a sufficient condition, but when we keep reading to "there can be no... without...", this should raise an alarm. Since there is a no..without, we can diagram the logic relation as: CMCF + not NCI --> not IG. the rest of the steps is the same as in the video.

This is what everyone was asking about previously, and something that troubled me a bit as well, since there is no response, this is a correct way of doing it yeah?

@NativeJustice and @Emanuel-Centeno, the only issue with this is that the CMCF part of the discussion doesn't interact with the rest of the logic in the question in a meaningful way, as it is more of an overarching precondition than an active part of the logical discussion. This diagram works, but it's superfluous. The use of "if" in the initial statement is essentially a misdirect on the LSAT maker's part, and you need to be aware of that while indicator words can be helpful, you cannot follow them slavishly. You can diagram it like this, but it just muddies the waters, and I wouldn't recommend it.
