question:
Passage: Burke was a leading sceptic with respect to democracy. While admitting that theoretically, in some cases it might be desirable, he insisted a democratic government in Britain in his day would not only be inept, but also oppressive. He opposed democracy for three basic reasons. First, government required a degree of intelligence and breadth of knowledge of the sort that occurred rarely among the common people. Second, he thought that if they had the vote, common people had dangerous and angry passions that could be aroused easily by demagogues; he feared that the authoritarian impulses that could be empowered by these passions would undermine cherished traditions and established religion, leading to violence and confiscation of property. Third, Burke warned that democracy would create a tyranny over unpopular minorities, who needed the protection of the upper classes.

What type of government system did Burke favor?
