The best explanation as to why direct democracy would not work well in the united states is that a. voting is not mandatory in the united states. b. the use of direct democracy would make debate on issues by individuals too difficult. c. ancient greece was smaller and less geographically diverse than the united states. d. the population of the united states is too large.

D. the population of the united states is too largeit would be impossible to account for the interests of every individual in the us. this is why we are a representative democracy and elect officials to represent our interests. direct democracy really only functions in very small, local governments.

D. the population of the united states is too large    the us general population is far too diverse and the population too large.  there is bound to be issues and disagreements on almost all laws that would be passed.  with the amount of laws being passed in the state and national government nowadays, people would literally spend most of their waking hour voting rather than being useful members of the society,
