Which term means an addition to something designed to improve or complete it?

• A. Supplement
• B. Supplementary
• C. Survive
• D. Susceptible

Answer: (B)

The idea here is recognizing a word that describes something added to enhance or complete something else. Supplementary means added to support or extend the main part, often used as an adjective for additions like material, information, or instructions that accompany the primary item. You’ll see it in phrases such as supplementary materials or supplementary information, signaling that these extras are meant to improve understanding or completeness. That sense of “an addition designed to improve or complete it” fits best. The other words don’t convey this idea: survive relates to continuing to live, and susceptible means likely to be affected or influenced, neither of which refer to an added enhancement.
