Final answer:
Europeans had more advanced weaponry due to technological advancements, access to resources, and arms race among native populations. Major advances in weapons technology also played a role.
Step-by-step explanation:
Europeans had more advanced weaponry than the Old World mainly because of their technological advancements and access to resources. They had perfected the use of machine guns, long-range artillery, trenches, and barbed wire. The influx of European materials also led to an arms race among native populations, who refashioned European brassware into arrow points and traded for muskets. Major advances in weapons technology, such as the development of breech-loading rifles and machine guns, also gave Europeans a significant advantage.
