Which of these events during the Age of Exploration was a cause of the other three?

A)
warfare increased as European nations competed for land and power

B)
advances in learning and technology made long ocean voyages possible

C)
Europeans brought food, animals, and ideas from one continent to another

D)
European diseases had an adverse effect on the native populations of new territories

B- advances in learning and technology made long ocean voyages possible

it's B

To determine which event during the Age of Exploration was a cause of the other three, we need to analyze the relationships between the events:

A) Warfare increased as European nations competed for land and power.
B) Advances in learning and technology made long ocean voyages possible.
C) Europeans brought food, animals, and ideas from one continent to another.
D) European diseases had an adverse effect on the native populations of new territories.

From these events, we can see that advances in learning and technology (B) made long ocean voyages possible. This, in turn, enabled Europeans to explore new territories and establish trade routes with other continents. This exploration and trade led to Europeans bringing food, animals, and ideas from one continent to another (C) as they encountered new cultures and resources.

Additionally, these extended voyages and interactions with new populations resulted in European diseases being introduced to native populations (D), which had an adverse effect on them due to lack of immunity.

Lastly, as exploration and colonization increased, European nations competed with each other for land and power (A). This competition led to conflicts and warfare.

Therefore, advances in learning and technology (B) directly preceded Europeans bringing food, animals, and ideas from one continent to another (C), and this exploration and trade ultimately led to European diseases affecting native populations (D). The increased competition among European nations (A) can be seen as a result of the expansion and colonization resulting from the other three events.
