Which of the following is the primary function of a parliament?

Step 1: Analyze the question The question asks for the primary (main, most important) function of a parliament. Parliaments have several roles, but we need the one that defines them.

Step 2: Explain the concept A parliament is the legislative arm of government. The word "legislature" comes from "legis," meaning law. Its core duties include:

• Lawmaking (legislation): its main and defining function
• Representation: speaking for the people
• Oversight: checking the executive through questions, committees and investigations
• Control of finance: approving the budget and taxation

Step 3: Evaluate each option

• A. Impeachment of the president: this is a power the legislature can use, but only in rare cases of serious misconduct. It is a checking power, not the routine primary function.
• B. Making of laws: this is the main reason a parliament exists. Every other function supports or complements it.
• C. Ratifying international treaties: a secondary function, and in some systems, such as the American Senate, it is only a part of the legislature's role.
• D. Acting as an electoral college: a limited function in a few countries, for example electing a president in some systems. It is not a primary function.

Step 4: Answer The primary function of a parliament is making laws, which is option B.

Step 5: Exam tip When you see "primary" or "main function" with a legislature, think law-making. For the three arms of government, remember:

• Legislature → makes laws
• Executive → implements laws
• Judiciary → interprets laws

Options like impeachment, ratification and electoral roles are usually secondary or special functions.
