Don Crabtree's experimental flintknapping research
a. failed to discover any successful ways in which Folsom projectile points could be fluted in spite of decades of research; flintknappers today still don't understand how to produce a flute.
b. discovered successful ways in which Folsom projectile points could be fluted, and stimulated additional research resulting in the discovery of more successful fluting methods.
c. discovered the purpose of the flute in Folsom projectile points; fluting was part of a pre-hunting ritual designed to ensure hunting success.
d. showed that the fluting of Folsom projectile points was actually a simple process that any minimally skilled flintknapper (by today's standards) could accomplish with relative ease.
e. was reputedly faked and therefore not taken seriously by archaeologists.
Question 2
When discussing projectile points, a flute refers to all of the following except:
a. a distinctive characteristic of Clovis and Folsom projectile points.
b. a wide, shallow, longitudinal groove on the face of a projectile point.
c. the feature that is created by the removal of a channel flake.
d. a thin, sharp sliver of stone removed from the core
e. formed by the removal of one or more flakes from the point's base
