Question

The Stillwater Marsh burial population had a remarkably low percentage of dental caries because:
a. Grit from plant food ground on metates was incorporated into their diet; this grit acted as a natural abrasive and helped to clean their teeth.
b. They ate very little meat, largely subsisting on maize agriculture.
c. They were strictly hunter-gatherers, and so their diet was very low in simple carbohydrates and starches.
d. None of the above; the Stillwater Marsh burial population had an extremely high percentage of dental caries because their diet was high in carbohydrates.
