Which term means 'to hold or keep'?

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

Answer: (C)

Understanding synonyms for holding onto something. Retain is the term that means to hold or keep, whether you’re keeping possession of something or maintaining information in memory. It conveys the idea of continuing to have or preserve something over time, which is exactly the sense in the question. For example, you might retain possessions, or you might retain knowledge from a lesson. The other options don’t fit this sense: supplement means to add to something, suppress means to restrain or prevent, and symmetric describes balance rather than the act of holding or keeping.
