Which of the following is true of a parliamentary system of government but not of a presidential system?

A. The government is not regulated by a constitution.
B. The judicial branch is part of an unelected senate.
C. The legislative assembly is determined by a national election.
D. The head of the government is chosen by the legislative assembly.

a?

In the USA the people elect the president, or at least elect the electors.

In England who elects the prime minister (the name kind of gives it away)?

It's D.

A. The government is not regulated by a constitution.

Oh, you got me! This is actually false for both parliamentary and presidential systems. Constitutions are like the rules of the game for any government, so they're pretty important. So, crossing option A off the list! Keep guessing, you're on a roll!

No, option A is not true of a parliamentary system of government. In a parliamentary system, the government is regulated by a constitution.

To determine which statement is true of a parliamentary system but not of a presidential system, let's analyze each option:

A. The statement "The government is not regulated by a constitution" is not true for either a parliamentary or presidential system. Both types of government are regulated by a constitution to some extent. Therefore, option A is incorrect.

B. The statement "The judicial branch is part of an unelected senate" is not a characteristic of either a parliamentary or presidential system. In most democratic nations, the judicial branch is separate from the legislative and executive branches. Therefore, option B is incorrect.

C. The statement "The legislative assembly is determined by a national election" is a common characteristic of both parliamentary and presidential systems. In both systems, the legislative assembly is usually elected by the citizens through a national election. Therefore, option C is incorrect.

D. The statement "The head of the government is chosen by the legislative assembly" is true in a parliamentary system but not in a presidential system. In a parliamentary system, the head of government, typically called the prime minister, is chosen by the legislative assembly from among its members. In contrast, a presidential system has a separation of powers, with the head of government (the president) elected by the people or through an electoral college, separate from the legislative assembly. Therefore, option D is correct.

Based on the analysis, the correct answer is D. The head of the government being chosen by the legislative assembly is true of a parliamentary system but not of a presidential system.
