Final answer:
Wampum was not introduced by Europeans; it was already used by indigenous peoples, whereas glass beads, copper kettles, and metal tools were introduced by Europeans.
Step-by-step explanation:
When Europeans arrived in the Americas, they introduced a variety of goods and materials to the Native American people. Among these newly introduced items were glass beads, copper kettles, and metal tools. These items were often used in trade and had a significant impact on local economies and social practices. However, wampum, which is option A, is not the correct answer as it was not introduced by Europeans to Native Americans but was already in use by indigenous peoples as a form of currency and ceremonial exchange.
