The correct answer is mysterious
Answer:
Hey, what's up?
"What's up" can be considered to be slang.
Thank you very much.
This sentence does not use slang; it is a very professional sentence.
I'm just going to chill today.
The word "chill" is slang.
That's a sweet thing to say.
This sentence does not contain any slang words.
Drew got busted.
"Busted" is a slang word.
Therefore, the 3 sentences with slang are:
Hey, what's up, I'm just going to chill today and Drew got busted.
In dramatic structure, I think dialogue is used to appeal to the reader by making he/she feel like they are actually there and to just bring it to life. Hope that helps.
I'll just rewrite the sentence how it's supposed to sound...
My bike tire was low, i wasn't surprised that it went flat just as it began to rain.
