Answer:
3/5 Compromise.
Explanation:
A constitution refers to a set of written laws and principles which is typically used to determine the power and authority of the government, as well as guarantee the fundamental rights of its citizens.
The Three-fifths Compromise was a compromise reached among delegates who came from the southern and northern states during the United States Constitutional Convention which held in 1787.
These delegates had disputes on how slaves are to be counted during census to determine the total population of each state which, consequently would determine the amount of taxes to be paid, as well as the number of house of representative seats. They reached a compromise by agreeing that three-fifths (three out of five) of the slave population are going to be counted to determine direct taxation and representation in the house of representatives.
Hence, the compromise that was made to make the Constitution appeal to the southern state was the Three-Fifths Compromise.
It would be the development in agricultural knowledge/technology
Development in agriculture enable hunter/gatherer society to shift their behavior. Before this, they had to keep moving from one place to another in order to seek food to live.
After the development in agricultural knowledge/technology, the society now can stay in one exact place for a long period of time and relied on agricultural product as their main source food.
After living in one same place for a long time, the needs to build things to accommodate their living start to arise. They start to built several things and repeat the process every year. In the end, large cities were developed from the initially small hunter/gatherer society.
