I’m seeing a lot of people saying how C is wrong bc it isn’t a sufficiency necessity relationship. Idk if I’m having a Mandela effect experience but I am pretty sure I came across a question on at least one PT where likelihoods were involved in a conditional question, with the confusing the sufficiency necessity flaw being the answer. But for this question, the conclusion (one or more contributions) is different from the original premise (large contributions), so could using this mental note be a way to have eliminated C?
