(spoiler alert if you havent taken PT41) :
its the question that begins with "poor nutrition is at the root....."
the logic in the argument seems to me to look like "high nutrient diet ---> improved behavior ".........but the credited response was answer choice E which states " ~high nutrient diet-----> ~improved behavior"
intuitively, this answer choice feels correct, but wouldnt this be whats called "denial of the antecedent"?? other books call it illegal negation or denying the sufficient condition, but the point i guess is that its logically invalid. and yet that invalid logical structure is present in the correct answer choice for this question. Can someone explain that to me? thank you
