Not giving up or stopping.

• A. Persistent
• B. Annual
• C. Transfer (a Phone Call)
• D. Entry Level

Answer: (A)

Not giving up or stopping means continuing to try even when things get tough. That ongoing, determined effort is described by the word persistent. When someone is persistent, they keep working toward a goal and don’t quit easily, no matter the obstacles.

The other ideas don’t fit this sense: annual refers to something that happens once a year, which has nothing to do with effort; a transfer (a phone call) describes routing a call, not perseverance; and entry level describes a starting position, not the quality of continuing to push forward.

So the best fit for not giving up or stopping is persistent. For example, someone who keeps studying a difficult topic day after day, despite slow progress, is demonstrating persistent effort.
