<em>B. Many of them died during the migration.</em>
Explanation:
The Trail of Tears was the walk the Native Americans did after being forced from their land by the United States government.
The U.S. government wanted to expand, but Native Americans were living in the land they wanted to expand into, so decided to move them to present day Oklahoma, where they were not planning on doing anything with quite yet.
The Indian Removal Act was officially passed in 1830, which finally made it so the Natives had to leave or they would be forcefully thrown out. They did not want to leave and some even tried to revolt, but it was no use, as they did not have the resources or man power against the United States government.
Since they did not leave while planned and had to be forced out of their homes, many were not properly prepared. They were forced to walk and be kept in camps along the way. Many ended up dying from diseases, starvation, or because of the weather. This walk is called the Trail of Tears, where <em>thousands </em>of Native Americans died.
The structures that were used for religious and social activities, and as houses for chieftains and burial sites were Mounds.
<h3>What structure was used for chieftains and burial sites?</h3>
The Native American cultures that were found in the Mississippi area would use mounds for religious festivals where they would offer worship to their gods. They also used mounds for social activities and events.
It is also intriguing to note that these mounds would also be burial sites which meant that the Native Americans here wanted to feel closer to their dead ancestors. This was also the structure that chieftains used for their houses.

Constantinople was able to survive due to its <em>strategic</em> location and <em>sofisticated</em> system of fortifications.
Constantinople was able to survive as the <em>central</em> hub of the European culture throughout the early 1000s due to its strategic location, the city was located in a strait between the Black and Mediterranean Seas, between Europe and Asia, which allowed the city to be prevented from many invaders, from Hunes to Arabs.
In addition, the city counted with a sophisticated system of fortifications which made impossible any attempt of siege until the appearance of first developments on modern artillery in the 15th Century, and the city was well communicated with the most important nations in Eastern and Western Europe by sea (i.e. Italy, Carolingian Empire, Kiev' Rus), of which the city may receive reinforcements in desperate situations.
