Niger and Congo are two rivers after which countries are named (actually in both cases two countries each) - and those are African countries, so they must be in Africa.
Zambezi is a river in Angola and Namibia.
Tigris is a River in Mesopotamia, in Asia - so that's the correct answer!
By setting one of them in bin I think that is the answer
Tenochtitlan was unique because it was located in a lake, thus being built in a place totally surrounded by water.
Explanation:
The capital of the Aztecs was Tenochtitlan. This city was the center of power, and the center of pretty much everything in the Aztec society. This city was located in a unique environment though, more specifically in a lake.
After the Aztecs were defeated by their rivals, they escaped to an island in a lake. They started to live on this island, built a city, and despite the initial difficulties, they managed to survive and prosper. The city was named Tenochtitlan, and the city's location, initially being a huge challenge, turned out to be a big advantage, as being totally surrounded by water was an excellent natural defense.
The Aztecs started to engage in agriculture, and were constructing small pieces of land in the lake itself, cut through with small canals. Things provided them with enough food to sustain themselves. As the Aztecs were becoming more powerful, they started to attack and conquer the neighboring civilizations, eventually building an empire.
The empire was built on the basis of the Triple Alliance between:
- Tenochtitlan
- Texcoco
- Tlacopan
