The accurate example of how civilizations were impacted by physical geography is: The Saharan Desert was a physical boundary that isolated North and South Africa from one another.

To arrive at this answer, we can analyze each option:

1. The Swahili in Africa were exposed to Christianity by Arab traders due to the trade winds of the Indian Ocean.
This option talks about trade winds influencing the exposure of the Swahili people to Christianity. However, it does not directly link the influence to physical geography.

2. The governments and religions of Southeast Asia were similar to Eurasia because it was connected by rivers.
This option suggests that the similarities between the governments and religions of Southeast Asia and Eurasia were due to being connected by rivers. However, while physical geography might have played a role in facilitating interaction, it does not clearly describe how it impacted the civilizations.

3. North and South China were united throughout history because of a lack of physical barriers.
This option claims that North and South China were united throughout history due to a lack of physical barriers. While geography played a role, particularly in terms of ease of communication and transportation, it does not provide sufficient evidence to support the claim.

4. The Saharan Desert was a physical boundary that isolated North and South Africa from one another.
This option describes how the Saharan Desert acted as a physical boundary, creating isolation between North and South Africa. This physical barrier impacted the civilizations in terms of limited interaction, cultural differences, and distinct development.

Therefore, option 4 is the accurate example of how civilizations were impacted by physical geography.
