Which answer best summarizes the key elements of the great compromise?
one house: representation based only on the state population
one house: equal representation from each state regardless of the population
two houses: equal representation from each state, and representation based on state population
two houses: representation based on state population, and representation based on state land mass

The answer that best summarizes the key elements of the Great Compromise would be "Two houses: equal representation from each state, and representation based on state population," since this satisfied both the small and large states by calling for two houses in the legislature: the Senate and the House of Representatives, with the Senate having a set number of representatives per state (which favored the smaller states), and the House having representatives based on state population size (which favored the larger states).
