Reading the passage
My first thought is that both accounts examine how carbohydrate consumption relates to tooth decay. A explains the usual relationship, while B examines a population that doesn't follow the expected pattern.
What we’re looking for
Let's check how the choices describe the topic and whether they cover both accounts.
Working the answers
- ACorrect
This is broader than my initial prediction, but it fits. A explicitly begins with using prehistoric teeth as clues to the transition toward agriculture. B examines recovered remains from a population whose reliance on agriculture increased. The dental findings are part of the archaeological evidence we use to understand that development, including the limits of the usual dental indicator.
- B
B briefly mentions overall health, but both accounts concentrate on teeth. This expands the topic beyond the issue they actually examine together.
- C
The food-and-decay relationship looks promising, but “strictly agricultural societies” is wrong. A includes nonagricultural populations, and Ban Chiang's early economy combined hunting, gathering, and cultivation.
- D
Neither account tries to establish when the first agricultural society arose. Studying changes in particular populations doesn't answer that first-ever question.
- E
A shows that nonagricultural people obtained carbohydrate-rich foods. The focus isn't how much access they had, however; it's what those foods can tell us about diet and tooth decay.
