Quick decision making is an advantage of

Step 1: Analyze the question The question asks which system or concept makes decision making fast.

Step 2: Explain the concepts

• Unicameralism: A legislature with only one chamber. A bill does not have to pass through a second house, so laws are made faster and with less cost and less deadlock.
• Constitutionalism: The idea that government power is limited by a constitution. It is about the rule of law, not speed.
• Federalism: Power is shared between central and regional governments. Consultation between levels often slows decisions.
• Republicanism: A system in which the head of state is not a monarch and is elected. It says nothing about how fast decisions are made.

Step 3: Work through the options

• Unicameralism means one legislative house, so there is no delay from a second chamber reviewing, amending, or rejecting a bill. This gives quick decision making.
• Federalism is typically slower because of overlapping powers and negotiation.
• Constitutionalism and republicanism are about limits on power and the type of head of state, not the speed of lawmaking.

Step 4: Answer The correct answer is A. unicameralism.

Exam tip: Match the prefix. "Uni" means one, so one chamber means a simpler and quicker process. In contrast, bicameralism (two chambers) is known for thorough scrutiny but slower lawmaking. Remember "Uni = Unified and Quick."
