What of the following describes a major difference between the first and second waves of European imperialism?

A major difference between the first and second waves of European Imperialism lies in their motivations and methods. The first wave, from the late 15th to the 18th century, was primarily driven by exploration, trade, and the spread of Christianity, focusing on the Americas and parts of Asia. In contrast, the second wave, during the late 19th to early 20th century, was characterized by industrialization and competition for resources, leading to the aggressive colonization of Africa and Asia, often justified by a sense of racial superiority and the desire for strategic dominance. Additionally, the second wave saw more direct political control and administration over colonies.
