Citizens elect leaders who vote on the issues in a representative democracy, and citizens vote on the issues in a direct democracy.
Explanation:
This is true, while the rest are false. Representative democracy was designed for large groups, not small, and direct democracies are designed for small, not large groups. The last option is wrong because the reason citizens elect their representative is so they can represent their desires and needs. And as for the 2nd option that representative democracy is modern and direct democracy is ancient, that just isn't a valid reason.
