Question

What is the rewrite going to be I don’t understand what I have to do

Answer 1

You have to make the phrase given grammatically correct and then explain your answer on the line beneath it. In this case, the rewrite would be "no dogs allowed" because the apostrophe is possessive. You would only use such an apostrophe if you were to say, for example, "Susy's instrument" referring to something she possesses.
