Hi @RayJ,

Thanks for the question! So we’re being asked here for something that both passages use as evidence to support the prevailing view about the relationship between dental caries and carbohydrate consumption. Remember, it’s important that this answer choice be mentioned in both passages, not just one or the other.

Now take a look at (B), which tells us that this evidence is the relatively low incidence of caries among nonagricultural people. Well, again, the correct answer choice should be mentioned in both passages. Is this mentioned in passage A? Yes, it is. Take a look at the second paragraph of passage A, where indigenous populations like the Sioux who primarily consumed meat are compared to others, and this shows that the greater a population’s dependence on agriculture, the higher its rate of caries formation. So this is found in passage A.

Now is (B) found in passage B? Again, yes; take a look at the second paragraph of passage B between lines 41-42, where we’re told that dental caries is uncommon in pre-agricultural populations. Since (B) is found in both passages as evidence supporting the prevailing view about the relationship between dental caries and carbohydrate consumption, it’s the correct answer.

Hope this helps! Feel free to ask any other questions that you might have.
