I have this sentence: Whos in the office now?

My answer choices are Whos in, Whose in, Who is in, Who's in, and Whose in'.
I selected Who is in as my answer and that is incorrect. Could anyone explian to me why that is?

Who is = correct, when the words are spelled out.

But I think your teacher wants you to figure out the word that sounds like "whos" but is correct for the sentence. Which contraction meets that requirement? Which word means the same thing as "who is"?

The correct answer is "Who's in."

The sentence asks about the people present in the office at the moment. To properly construct this question, we need to use the contraction "who's," which is short for "who is."

Let's break it down further:

- "Who's" is a contraction of "who is."
- The word "who" is used to inquire about people.
- The word "is" is the third person singular form of the verb "to be."

So when we say "Who's in the office now?" we are essentially asking "Who is in the office now?"

The incorrect answer choices are:
- "Whos in" is missing the apostrophe in "who's" and lacks the verb "is."
- "Whose in" is incorrect because "whose" is a possessive pronoun and does not fit grammatically in this context.
- "Who is in" is similar to the correct answer but does not use the contraction form "who's."
- "Whose in'" is incorrect because it combines "whose" with an apostrophe after the "n," which is not grammatically valid.

Therefore, "Who's in" is the correct answer in this case.
