The manager insisted that the project would proceed ___ schedule.

The manager insisted that the project would proceed ___ schedule.

• A. In
• B. By
• C. On
• D. At

Answer: (C)

This item tests choosing the right preposition with a timetable to show that something is happening as planned. The natural expression with a schedule is on schedule, meaning the project is progressing according to the planned timetable and on time. That’s why the sentence reads smoothly as “The manager insisted that the project would proceed on schedule.” The other prepositions don’t form the common collocation you need here. In, by, or at with schedule aren’t used to express adherence to a timetable in this sense. If you wanted to describe being late or early, you’d use behind schedule or ahead of schedule, respectively.
