Explanation:

• Incorrect - The Levallois Technique is not related to making perforated Harappa pottery. Harappa refers to one of the major sites of the Indus Valley Civilization, and the Levallois Technique is not connected to it.

• Correct - The Levallois Technique is a method of making prehistoric flake tools. It is named after the Levallois-Perret suburb of Paris, where evidence of this technique was first found. The technique involves striking flakes from a prepared stone core in a specific way to create tools with a predetermined shape and size. This method was used during the Paleolithic era and represents an advance in stone tool-making skills.
