Reading the passage
Both accounts link carbohydrate-rich diets with tooth decay, but neither gives us an exceptionless farming-to-cavities rule. A includes nonagricultural people with high decay rates; B gives us a farming population whose rate fell. Keep those qualifications in mind when checking what both authors would accept.
Working the answers
- A
Time alone doesn't establish a predictable increase. Ban Chiang actually had slightly less decay in the later group.
- B
Neither account tells us how difficult decay is to detect in recovered teeth. Using those teeth as evidence doesn't establish that detection is often difficult.
- C
This reverses the general pattern: agricultural diets tend to produce more decay. Exceptions don't establish the opposite trend.
- DCorrect
Farming and decay don't necessarily track each other directly. A's gathered carbohydrate-rich foods can produce high rates without agriculture. B's increased reliance on agriculture doesn't produce a higher rate. Both therefore support the qualification in D.
- E
Tooth wear is discussed in B, but the authors don't rank its influence against that of particular foods. Mentioning both factors doesn't establish that one is more strongly linked to decay.
