Which statement best defines persistent?

• A. unending; unstopping
• B. constant
• C. stubborn; not willing to give up
• D. temporary

Answer: (A)

Persistent describes something that keeps going over time, without stopping. That ongoing, unceasing sense is why unending; unstopping fits best here, since it highlights the idea of continuing effort or presence rather than something fleeting.

Think of a persistent rain that lasts for hours or a persistent effort to solve a problem that continues until it’s done. It’s about duration and continuation, not just being steady or stubborn.

The other options are less precise: constant can mean steady but doesn’t always convey the idea of continued action despite obstacles; stubborn points to a mindset more than the act of continuing itself; temporary is the opposite of persistent, since it implies short-lived.
