Which term means first?

• A. Rationale
• B. Primary
• C. Prognosis
• D. Priority

Answer: (B)

The idea here is to identify a word that means “first” in its most direct sense. Primary is the best fit because it literally denotes something that comes first in order or importance—the main, chief, or initial element. It’s used in everyday language to describe the primary objective, the primary source, or the primary reason, all of which center on being first or most important.

Rationale refers to the reasoning behind a choice, prognosis is the forecast of a disease’s outcome, and priority describes something that should be addressed before others or is of high importance, but it’s about sequencing or urgency rather than being the direct synonym for “first.”
