Which prefix indicates "before"?

• A. Before, in front of
• B. After
• C. Foot
• D. Many

Answer: (A)

Prefixes that express timing or position tell us when or where something occurs. When a prefix means before, it signals that the action or location happens earlier or ahead of something else. The option described as “Before, in front of” fits this idea, because that sense is exactly what the prefix pre- conveys in medical terms (as in prenatal, prehospital, preview). The other ideas point to different meanings—after maps to post-, foot to ped- or pod-, and many to multi- or poly-. So the best choice is the one whose meaning is before/in front of.
