Reading the passage
Return to the main point we predicted: cooking may have helped shape human digestive anatomy. The authors challenge an expectation, develop that explanation through teeth, jaws, and the gut, and call for further testing.
What we’re looking for
So the central action is proposing an explanation. We should not choose an answer that captures only the opening misconception or the remaining uncertainty while leaving out what the authors offer in response.
Working the answers
- A
There is a puzzle about our anatomy and our difficulty surviving on raw food. But the authors do not stop at describing it; they propose cooking as part of the explanation. A leaves out their contribution.
- B
They do identify the assumption that cooking is too recent to matter. That is an obstacle they address on the way to developing their own claim. The misconception is not the subject of the entire discussion.
- C
Explaining what an already-given hypothesis means is different from putting an explanation forward and examining the evidence for it. The authors are arguing for cooking's possible role, not merely defining the content of someone else's hypothesis.
- DCorrect
They propose that adaptation to cooked food influenced human digestive anatomy. Teeth and jaws provide possible evidence, and the final paragraph presents cooking as a model worth testing against the raw-meat model. A hypothesis can concern what happened in the past; it need not predict a future event.
- E
Criticizing an assumption is part of the argument, but the central purpose is constructive: to offer the cooking explanation. Reducing the whole discussion to undermining a scientific principle misses the anatomical account the authors develop.
