   The human body is able to extract a similar number of calories from cooked food

   Like A, if this is true, it weakens the argument that we need to cook to get sufficient calories for those big juicy brains of ours.

   The human body uses more calories to process raw food than it uses to

   Why this is right

   But boy is this one subtle! Our prediction was something that establishes we need to cook to get enough calories for our brains to be so big. That could take many forms, including a comparison of the caloric content of cooked food vs. raw food. But caloric content isn't the only relevant factor. How many of those calories we can actually extract is relevant, which answer choice C alludes to. How many calories we spend on that extraction is also relevant, and that's what makes D correct. If we have to spend more calories to process raw food than we do to process cooked food, that strengthens the argument that you'll end up with more calories overall when you cook. Think of it like profit in sales. The profit is the amount of money you collect on top of what you spent to make the thing you're selling. If you spend less to make the thing, you profit more. Similarly, if you spend fewer calories digesting cooked food, you net more calories when you eat cooked food.

   Skill tested: Strengthen · how this choice captures the argument's function is the move to repeat next time.
