Why did some people think the Three-Fifths Compromise encouraged slavery?

The Three-Fifths Compromise counted three-fifths of the enslaved population when allocating seats in the House of Representatives. That gave states with more enslaved people greater representation and political power, even though enslaved people could not vote. Some people therefore thought the compromise encouraged enslavers to maintain slavery. The correct choice is “It increased the political power of enslavers.”
