Final answer:
The concept of popular sovereignty in the Great Compromise allowed for people to govern themselves within the structure of government, with equal representation in the Senate and proportional representation in the House of Representatives.
Step-by-step explanation:
The concept of popular sovereignty applies to the Great Compromise in the way it allowed for the idea of people governing themselves within the structure of government.
The Great Compromise proposed a bicameral congress, with the upper house, the Senate, having equal representation for each state, while the lower house, the House of Representatives, had representation based on the population of each state. This compromise ensured that both large and small states had a voice in the government.
