Reading the passage
We need evidence mentioned in both accounts, and it must support the usual carbohydrate-and-decay relationship. An interesting exception or a mechanism discussed in only one account won't satisfy both parts of the question.
Working the answers
- A
A mentions processed acorn flour, but B doesn't make that same observation about processed foods. Its discussion of starchy, sticky foods isn't automatically a discussion of processing.
- BCorrect
A gives the Sioux sample with almost no decay alongside the higher-decay maize-dependent sample. B states that decay is “uncommon in pre-agricultural populations.” Both use low decay among populations less dependent on agricultural staples as evidence for the usual relationship.
- C
B discusses fiber and grit; A doesn't. This fails the both-accounts requirement.
- D
A discusses wild foods and decay, but not their effect on tooth wear. B's separate discussion of wear doesn't give us the same evidence in both.
- E
B introduces a broader claim about declining health. A focuses on dental decay, so overall human health isn't the evidence both supply.
