Newcomer Designed Blind Experiments to Test the Accuracy of Keeley's

Multiple Choice

Newcomer designed blind experiments to test the accuracy of Keeley's high-power microscopy method of identifying stone tool microwear. These experiments:

A) established the validity of Keeley's high-power microscopic method; Keeley was able to correctly identify the microwear on many of the experimental stone tools.
B) determined that while high-power microscopic identifications could always be correctly made on the type of material worked, identifying the area of the tool actually used was much more difficult.
C) showed that while high-power microscopic analysis can be useful, it is not as effective as low-power analysis in determining microwear.
D) showed that high-power microscopic analysis is useless in determining microwear.
