Passage - General Questions

[lathlee]

would it be fair to consider this is the hardest passage of prep test 84 RC ? all my wrongs came from this passage

[Adam Tyson]

I think it's all relative, lathlee, and your difficulty with that passage could have had as much to do with time pressure as with inherent difficulty. This passage did not seem to me to be substantially more difficult than the others, either in the reading or in the difficulty level of the questions.

What exactly is the hypothesis in this passage? that changes in human anatomy like teeth and jaw size and digestive system stem from the rise of cooking? I'm a little confused because the author suggested two theories the first one was cooking and the second was eating a lot meat so idk which one is it.

[Adam Tyson]

The author is arguing that cooking could be the cause of some elements of human evolution, ashpine, and is challenging the claim that we evolved in those ways because of a high raw-meat diet. They are not supporting the raw-meat hypothesis, but bringing up cooking as an alternative hypothesis, and in so doing they are challenging the claim that cooking is too recent a development to have had that sort of impact.
