Final answer:
The Three-Fifths Compromise indeed dealt with the issues of representation and taxation by counting five slaves as three free persons for these purposes, making the statement true.
Step-by-step explanation:
The question pertains to the Three-Fifths Compromise, which is a historical agreement that was made in the United States during the 1787 Constitutional Convention. The Three-Fifths Compromise indeed dealt with the issue of representation and taxation, declaring that for the purposes of representation in Congress and taxation, five slaves would be counted as three free persons. This meant that slaveholding states would have more representation in the House of Representatives and more electoral votes than if slaves had not been counted, but they would also have higher taxes based on population.
Therefore, the answer to the question is: a. True.
