Which term means 'to take in addition to or to complete'?

• A. retain
• B. supplement
• C. status
• D. symmetric

Answer: (B)

This question tests vocabulary understanding of a term meaning to add to or complete something. Supplement is the best choice because it directly means to add something extra to improve or complete a whole—such as taking a dietary supplement to add nutrients or adding material to supplement a curriculum. Retain means to keep or hold onto something; status refers to a position or condition; symmetric describes balance or likeness on both sides. Therefore, supplement correctly conveys the idea of adding to or completing. For example, you might supplement a meal with a side dish to make it more complete.
