Parliamentary government was first established in which country?

1. A

   Great Britain (U.K.)

   Parliamentary government, with a cabinet responsible to an elected legislature, first took modern shape in Great Britain. The Westminster model spread from the United Kingdom. This option is the official key.

2. B

   Belgium

   Belgium has a parliamentary monarchy, but it is a later adopter, not the first home of the system. This option is not the key.

3. C

   France

   France has moved among republican, imperial and semi-presidential forms; it is not the origin of parliamentary government. This option is therefore wrong.

4. D

   Switzerland

   Switzerland is the classic collegial federal executive with direct-democratic tools, not the mother of cabinet parliamentarism. This option is not the key.

Summary. Official key is (a) Great Britain (U.K.). Responsible cabinet government grew from British practice: a ministry that holds office while it retains the confidence of the Commons. Belgium and other European states copied later. France and Switzerland illustrate other executive designs. Only (a) is first.
