Which accurately describes how Portuguese exploration efforts affected native African civilizations?

1. to find a northwest passage to Asia and bolster trade with China
2. to claim North America for Portugal and gain access to its natural resources
3. to conquer the Aztec and Incan Empires and claim their gold
4. to spread Christianity to new lands and convert indigenous peoples

4 maybe?

If you eliminate the answer choices that have nothing to do with Africa, what’s left?

Yes. All the others have to do with other continents.

The accurate answer is 4. Portuguese exploration efforts in Africa were primarily driven by the goal of spreading Christianity to new lands and converting indigenous peoples.

To arrive at this answer, you can analyze the historical context of Portuguese exploration during the Age of Discovery in the 15th and 16th centuries. Here are some key points to consider:

1. Portugal's geographic location: Portugal is located on the western coast of the Iberian Peninsula, which provided it with a strategic position for maritime expeditions.

2. Trade with Asia: Portugal sought to establish direct trade routes with Asia in order to bypass the intermediaries, mainly Arab and Italian merchants, who controlled the lucrative spice trade. However, this goal specifically applies to Portuguese exploration efforts in regards to Asia, not native African civilizations.

3. North America and its resources: Portugal's exploration efforts were primarily focused on finding sea routes to Asia and establishing trade contacts with African kingdoms. North America and its resources were not a significant focus for the Portuguese during this period.

4. Conquest of the Aztec and Incan Empires: The conquest of the Aztec and Incan Empires was primarily carried out by the Spanish, not the Portuguese. Portuguese exploration efforts were focused on different regions, particularly Africa, and did not directly contribute to the conquest and claims of these empires.

5. Spread of Christianity: One of the significant objectives of Portuguese exploration was to spread Christianity to the lands they encountered. Portuguese explorers, such as Henry the Navigator, often brought along missionaries to convert the indigenous peoples they encountered to Christianity.

Considering these points, we can conclude that the accurate description of how Portuguese exploration efforts affected native African civilizations is that they aimed to spread Christianity to new lands and convert indigenous peoples.
