Every day, the US Congress makes thousands of decisions.
In a direct Democracy, the citizenry would need to all be involved in each of these decisions. There are so many, that it would basically turn into a full time job for all citizens.
So, to allow for the majority of people to engage in trade or commerce, indirect democracy allows the election of representatives who act on behalf of the citizenry.
The gran chaco is a plateau. hope this helps :)
