Be careful America. Carelessness is dangerous.

Below is a question from the August 2014 New York State Regents Exam in Integrated Algebra. Although it is multiple choice, I have left the choices out because they do not matter here.
Do you understand this question? If you do, you will recognize that it is written poorly.

You do NOT see the "parabolic path of a ball kicked by a young child". If you did, it would be in  two length based dimensions (a 3 dimensional perspective diagram might be going overboard...). The axis cannot be labeled as "time" if the graph is meant to represent a "path."

Below is an edited version of the problem that would have been fine.
