The phrase modifies B, a message.
When writing to get a job or college application, you should be totally honest. Like, raely put a joke or anything "funny" in it. Because when you fill these out, whatever you put in them, has to be true. Ex: Because, for one, if you get to the job/college, and can't do what you said you could do in the application. Your gonna get fired, or kicked out of college(maybe). It would be very embarrassing, and you could loose whatever you had.
I hope this makes sense, and I hope it helps!! Good luck ;)
