Which word indicates a time limit or end point, as in 'stay until noon'?

• A. Until
• B. Since
• C. During
• D. By

Answer: (A)

Time words that indicate when an action ends help decide this. “Until” signals the duration runs up to a specific end point. In “stay until noon,” you keep staying and then stop at noon. The other options describe different timing ideas: “since” points to when something began (and may continue); “during” marks a period in which something happens; “by” sets a deadline for finishing or arriving, not the exact end of a duration. So, the best choice is “until.”
