Contextualizing Period 1 Practice Test

A historian explains that European contact occurred during an era when Afro-Eurasian and American worlds became increasingly connected through oceanic travel. This integration reshaped diets, environments, and power relationships, but it began within preexisting Native regional diversity and European imperial competition. Which option best identifies the broader context for the Columbian Exchange in Period 1 (1491–1607)?

Secondary source context (Period 1, 1491–1607): European colonizers entered ecosystems with unfamiliar crops and climates. Native agricultural knowledge—such as maize cultivation and soil management—was adapted by newcomers, while European animals and plants altered landscapes.

Which choice best provides broader historical context for the exchange of agricultural practices in early colonies?
