B. That's what I do when I web for my writing.
It is a because if they can’t describe they can’t back it up and it can’t be 3 c
The answer is d. This sentence helps you separate the actual warning and the word "warning" by using a colon. The other sentences don't make sense because they don't have that.
Let's solve this through process of elimination. We know the first part isn't a question, because there are no words to indicate that. Answer choice D is out. Answer choice B doesn't make much sense either, because it doesn't show any end quotation mark to finish off a statement. Answer choice C, a comma, can not fit into this either, because there would have to be an "and" or something similar after the word "town". The only choice left is answer choice A. "The manager will be out of town; he won't be back until Monday."
