Question

The manager asked the team to complete the project _______ the end of the week.

• A. until
• B. by
• C. since
• D. for

Hint:

Use "by" to indicate deadlines or the latest time something must happen.

Answer 1

The Correct Option is B

The manager asked the team to complete the project _______ the end of the week.

In this context, it is essential to choose the correct preposition to convey the right meaning. Below is a brief explanation of each option:

1. Until: Indicates a continuous action that goes on up to a certain point. It is not suitable here as it suggests the action is happening continuously until the deadline, which is not the intended meaning.
2. By: Signifies a deadline for an action to be completed. This is the appropriate choice as it implies the action should be finished any time before or on the given deadline.
3. Since: References a starting point in time and would not make sense in this context, as it doesn’t relate to a deadline.
4. For: Indicates a period of time over which something happens, not a deadline, making it unsuitable here.

Considering the explanation above, the correct completion of the sentence is: by

Thus, the correct sentence is: The manager asked the team to complete the project by the end of the week.
