Information and Ideas practice question

An archaeologist claims that the flint blades from the site were used to cut grasses rather than to butcher animals.

Which finding, if true, would most directly support the archaeologist's claim?

  1. A. Under a microscope, the blades' edges show the glossy polish that forms when flint repeatedly cuts silica-rich plant stems, and no traces of blood or bone.Correct
  2. B. The blades are sharp.
  3. C. Animal bones were found elsewhere at the site.
  4. D. Flint was quarried nearby.

Answer: A. Under a microscope, the blades' edges show the glossy polish that forms when flint repeatedly cuts silica-rich plant stems, and no traces of blood or bone.

Plant polish present, animal traces absent: the wear tells the use.

Why the other answers are wrong

B. The blades are sharp.
Sharpness suits either use.
C. Animal bones were found elsewhere at the site.
Bones elsewhere don't show what these blades cut.
D. Flint was quarried nearby.
The source of the flint doesn't bear on its use.
