Help Mark choose the best way to answer his friend.
Mark bumps into a classmate on campus who says, "Hey Mark! How's it going?" Select ALL the natural and grammatically correct replies Mark could use.
The correct answers are Not bad, you? and Pretty good! How about you?
"How's it going?" is a casual, fixed expression used as a greeting to ask "How are you?" It does not actually ask where you are traveling!
Therefore, "I am going to the library" is a funny misunderstanding of the question. "It goes very well" sounds like a robotic translation from another language; native speakers use simple adjectives like "Good," "Pretty good," or "Not bad."
