Answer:
Did you take this course to get a better job and why?
Explanation:
Open ended questions are ones that cannot be answered by a simple Yes or No. So in this case adding the why to the end means a yes or no answer cannot solve for the why part. Making this question an Open Ended Question.
P.S. - You have to answer if you took the course and why because I don't have that answer for you. I cant make opinions about the things people want to do. Since i'm not taking the course.
