Final answer:
The Three-Fifths Compromise resolved how slaves would be counted for legislative representation and taxation, with three-fifths of the slave population being counted for these purposes. Hence, the statement is true.
Step-by-step explanation:
The Three-Fifths Compromise was an agreement reached during the 1787 United States Constitutional Convention. It addressed how slaves would be counted when determining a state's total population for legislative representation and taxation purposes. Under this compromise, only three-fifths of the slave population would be counted. This was a contentious issue as the more populous Northern states that had fewer slaves, and the Southern states with large slave populations, disagreed on how slaves should be counted.
Therefore, the statement that the Three-Fifths Compromise dealt with the issue of representation and taxation is true. It was a critical agreement in the shaping of the United States' legislative structure and had lasting effects on the political landscape of the early United States.
