LSAT Preptest 150, Section 1, Question 23

Passage 4: Evolution and Cooking

Explanation

A. The passage does not make any claims about the health benefits of a raw-food diet versus a traditional diet for modern humans.


B. While the passage discusses biological adaptations due to cooking, it does not state that humans would be unable to utilize cooked food without these adaptations. The adaptations constrain use of raw food, the inverse need not hold true.


C. There is no mention of the timeline for early humans controlling fire relative to the adoption of cooking food.


D. The passage does not correlate the standardization of a cooked food diet with the ability of humans to lead sedentary lives.


E. (Correct Response) The passage discusses the implications and evidence of early humans developing biological adaptations to a diet of cooked food but also notes that some questions remain about the limits of utilizing raw food, suggesting that there is not yet a definitive conclusion.

The passage points towards evidence that the adoption of cooked food has been significant in human evolution, but it also highlights that not all effects of cooking are definitively understood, aligning with option E.
