Aparliamentary democracy can be described as having three branches of government including an executive, legislative and judicial branch. the head of government is generally the prime minister and is elected by the members of parliament, who are voted in by the people. the head of the state is the president, who is generally in charge of functions and ceremonial duties. a presidential democracy can be described as having three branches of government including an executive, legislative and judicial branch. the president is the head of the executive branch and is elected separately from the legislative branch. the president also acts as the chief of state. based on the description above, which could be one advantage of a parliamentary democracy over a presidential democracy? a) the president has more time to work with parliament since stately duties are left up to the prime minister. b) laws may be passed more quickly because the legislative branch and executive branch are more closely tied together. c) the prime minister only has to answer to the people for re-election and does not have to make compromises with parliament. d) the prime minister is usually from a different political party than most members of parliament so there's lots of different viewpoints.
