Hi,

An assigment is a task/job/duty that you have been asked to complete. It is often used for a written piece work that students have to complete and send to their tutor/teacher by a certain date.

why can't we use who's instead of who? Can you explain please?

[Yankee]

Hi abdullahteke

Who's can be a contraction of either who is or who has.

(Who's?) is the short form of (who is....? or who has ......?), So using it refers to the singular which means the third person (He & She). But if we want to ask about persons in general using just one word we use (who?) whithout referring to the singular or the plural.
How do you feel about that?

Hi Nola

In this particular case, the only reason that you cannot use who's is that the word has is already in the sentence.
In other words, you cannot say "Who's has".

Hi Amy
But, can we use just the word (who?) without completing the question in our speaking? (when we don't want to refer to the singular or the plural)

Hi Nola

Yes, if the other person already knows what you're talking about, you can do that. You can also ask "Who?" in order to clarify. For example:

A: You'll never guess who she's dating now.
B: Who?
A: John.
B: Who? Who's John?
A: Her boss!
