Explanation:

Since the Parliament plays a central

role in modern democracies, most

large countries divide the role and

powers of the Parliament in two

parts. They are called Chambers or

Houses. One House is usually

directly elected by the people and

exercises the real power on behalf

of the people. The second House is

usually elected indirectly and

performs some special functions.

The most common work for the

second House is to look after the

interests of various states, regions

or federal units.
