Location

The factor that supported both Axum and the Swahili city-states in trading with other nations is location.

To arrive at this answer, let's go through each option individually:

1. Trade: While trade is indeed an important factor for both Axum and the Swahili city-states in their engagement with other nations, it is not a factor that is exclusive to them. Many civilizations throughout history have engaged in trade, so this option does not fully capture the specific support for these two entities.

2. Lack of competition: This option is not accurate because both Axum and the Swahili city-states did face competition in trading with other nations. There were numerous other civilizations and regions engaged in trade during their time. Thus, this factor did not solely support them in trading.

3. Language: Although language played a role in communication during the trading process, it is not a factor that solely supported both Axum and the Swahili city-states. Different languages were spoken among the various trading partners, and language alone was not sufficient to support their trading activities.

4. Location: This factor holds the correct explanation. Both Axum and the Swahili city-states were strategically located along the eastern coast of Africa, which provided them with advantageous positions for trade. Axum, located in present-day Ethiopia, was situated at the crossroads of major trade routes between the Mediterranean, the Arabian Peninsula, and the African interior. The Swahili city-states, found along the coast of East Africa, were perfectly positioned for maritime trade with Arabia, India, and other regions. Their favorable geographic location facilitated the exchange of goods, ideas, and culture, making trade with other nations accessible and lucrative.

Therefore, the correct answer is location, as it is the significant factor that supported both Axum and the Swahili city-states in trading with other nations.
