In an SSC idiom question, students should match the whole phrase with its accepted meaning rather than translate each word separately.

• Classroom example: Divide and rule can refer to a situation involving control people by making them disagree with each other.
• Story example: A writer may use Divide and rule when describing a situation involving control people by making them disagree with each other.
