Half-hearted means without full interest or effort. This answer is correct because the expression has a fixed figurative meaning in English. In an SSC idiom question, students should match the whole phrase with its accepted meaning rather than translate each word separately.

• Classroom example: Half-hearted can refer to a situation involving without full interest or effort.
• Story example: A writer may use Half-hearted when describing a situation involving without full interest or effort.
• Exam example: When a sentence contains Half-hearted, choose the meaning “without full interest or effort.”
