How is Britain's parliamentary system similar to a republic

Decision-makers are chosen by the monarch

Decision-makers are elected by the citizens

Decision-makers are appointed by the upper class

The option "Decision-makers are elected by the citizens" refers to a characteristic shared by both Britain's parliamentary system and a republic. In both systems, decision-makers, or representatives, are elected by the citizens through a voting process.

However, the options "Decision-makers are chosen by the monarch" and "Decision-makers are appointed by the upper class" do not accurately describe similarities between Britain's parliamentary system and a republic.

In a parliamentary system, such as that of Britain, decision-makers are elected by the citizens but the monarch's role is largely ceremonial and non-political. The monarch does not choose decision-makers in this system; their role is mainly symbolic and they are not involved in the decision-making process.

Similarly, in a republic, decision-makers are elected by the citizens, but their selection is not determined by the upper class. A republic is based on the idea of representative democracy, where all citizens have the right to vote and participate in the election of decision-makers.

Therefore, the similarity between Britain's parliamentary system and a republic lies in the fact that decision-makers are elected by the citizens.
