Which word means used in order to complete something; additional?

• A. Supplement
• B. Survey
• C. Suppress
• D. Supplementary

Answer: (D)

The concept here is choosing the word that describes something that is added to complete or enhance something. The best fit is supplementary, which means additional or used to complete what already exists. In contexts like “supplementary materials,” the term directly conveys something that is added to help complete or support the main thing.

Supplement, as a noun, refers to an added component, or as a verb means to add something to complete, but it doesn’t function as an adjective describing something as extra. Survey and suppress are unrelated in meaning. Suppressive would imply preventing or restraining, which isn’t about adding to complete.
