The Upper Paleolithic Blade Technology Was More Efficient Than Levallois

question 70

Multiple Choice

The Upper Paleolithic blade technology was more efficient than Levallois because:

• A) Levallois worked only on softer stones that could not maintain a sharp edge for very long
• B) Upper Paleolithic blades were struck from prepared cores and therefore were of a predetermined form, whereas Levallois flakes were struck off haphazardly produced cores and their form was unpredictable
• C) many more Upper Paleolithic blades than Levallois flakes could be removed from the same-sized core, producing more cutting edge from the same amount of stone
• D) blades are sharper than flakes
