Question

Fill in the blank with appropriate preposition.

I will have completed my task __ Friday. (till/by)​

Answer 1

I will have completed my task [by] Friday.

In this sentence, the appropriate preposition to fill in the blank is "by."

The preposition "by" is used to indicate a deadline or a specific point in time when an action is completed. In this case, the sentence is expressing that the task will be completed before Friday.

Here's an example to help clarify:

- If today is Wednesday and I say, "I will have completed my task by Friday," it means that I expect to finish the task at some point before Friday. It could be completed on Thursday or even earlier.

Using the preposition "till" would not be correct in this context because it implies that the task will continue until Friday, rather than being completed before Friday.

So, the correct preposition to fill in the blank is "by."

Answer 2

By

Step-by-step explanation:

The appropriate preposition to fill in the blank in the sentence "I will have completed my task __ Friday" is "by."

The preposition "by" is used to indicate a deadline or the latest time at which something will be completed. In this context, it suggests that the task will be finished before or on Friday.

Example: "I will have completed my report by Friday, so I can submit it to my professor."

On the other hand, the preposition "till" is used to indicate a duration or the time up to a particular point. It implies that the completion of the task will continue until Friday, without specifying if it will be completed before or on that day.

Example: "I will work on my project till Friday to make sure it is done perfectly."

Therefore, in the given sentence, "by" is the appropriate preposition to convey the meaning that the task will be completed before or on Friday.
