An aggregate of people organized to promote some objectives they have in common can be described as ........ group.

Analyze the question: We need the term for an aggregate (collection) of people who organize themselves to promote objectives they share. The key phrase is "organized to promote some objectives they have in common."

Explain the concept: In Government, a pressure group (also called an interest group) is an organized body of people who share common interests or objectives and work to promote or protect them, usually by influencing government policy and decisions, without seeking to take control of government themselves.

Examples in Nigeria: NLC (Nigerian Labour Congress), ASUU, NBA (Nigerian Bar Association), NANS, and Market Women's Associations.

Step-by-step evaluation of the options:

• A. Electoral group: This refers to people involved in elections, such as voters. It does not describe a group organized for common objectives. ✗
• B. Pressure group: This is an organized group with shared interests that works to promote those interests and influence government. ✓
• C. Political group: This would typically seek to win political power, as political parties do. The question does not mention contesting for power. ✗
• D. Professional group: This is a narrower type, based on a shared occupation (e.g., doctors, lawyers). It is a kind of pressure group, but the question is general. ✗
• E. Social group: This is a broad term for people who interact socially. It does not stress organizing to promote objectives. ✗

Answer: The general definition of an organized group promoting common objectives is a pressure group, so the answer is B.

Exam tip: Remember the keywords: "organized," "common interests/objectives," and "influence government" point to pressure group. If the question mentions "winning elections or controlling government," think political party instead.
