Which prefix means excessive, increased?

• A. Hyper-
• B. Post-
• C. Sub-
• D. Trans-

Answer: (A)

The idea being tested is a prefix that signals when something is above the normal level. Hyper- means over, above, or excessive. It’s used in medical terms to show increased amounts or activity: hyperglycemia (high blood sugar), hypertension (high blood pressure), hyperthermia (excessively high body temperature), hyperactivity (more activity than usual). The other prefixes here don’t convey extra amount: post- means after or behind in time; sub- means under or below; trans- means across or through. So hyper- is the best fit for “excessive, increased.”
