Multiple Choice

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.
