In hindsight I understand why D is correct (PT 3 section 2 Q 9), but I eliminated it because in the STIMULUS the comparison was to the same amount of whole milk. The question stem tells us that the coconut oil doesn't "usually cause" the blood cholesterol level to rise which allows us to consider the fact that people use more of one product than another. Is this type of chunky question stem that allows for a gap in reasoning that wasn't present in the stimulus happen in other LSAT LR questions? Or is this abnormal since it's a very old test?
