3. what was the capital of the byzantine empire? what was unique about this city?

The capital of the Byzantine Empire was Constantinople. They specifically chose that capital because it was centered between the Aeg and Black sea which would increase it's trade and also assert their dominance. Furthermore, it was the largest and richest's cities at that time.

i think the answer is c, rivers.

explanation:

sometimes, borders fall along natural boundaries like rivers or mountain ranges. for example, the boundary between france and spain follows the crest of the pyrenees mountains. for part of its length, the boundary between the united states and mexico follows a river called the rio grande. the borders of four countries divide africa’s lake chad: niger, chad, cameroon, and nigeria.
