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.
If an archaeological site is considered significant under the National Historic
Preservation Act, then it is:
a. Eligible for the National Register of Historic Places.
b. Automatically placed on the National Register of Historic Places.
c. Protected from all future activities that might be considered destructive, including
excavation.
d. Still likely to be destroyed prior to investigation, as a determination of significance
has no power to actually protect an archaeological site.
