[ It's not so much logic as much as Kaz shoots down all other possible choices, so it's just ATP left that Mafuyu circles. The reasoning is long and complicated so she'll just remember "mitochondria = ATP" and use that for all questions.
She'll probably defer to Kaz like this for the rest of the homework, her reading the question out loud and Kaz doing all the thinking for her while she circles whatever answer is left over... but they get through it, fast forward thirty questions and two hours later. She cannot, in fact, get partial credit on the paper, and who knows if there are any ice cream places open this late anymore, but they got through it...! ]
