Hi Sherral, 

Thank you for pointing out that this answer is shown twice.  I have corrected this so the answer appears once.  

The lesson questions are “practice-only” questions and they do not count toward your grade.  Once you fill-in-the-blanks, the system should prompt you to “check you answer” against the correct answer.  These questions are not supposed to be marked correct or incorrect so it really doesn’t matter if you enter a few words or an entire sentence.  The idea is to see if your answer matches the answer from the course.   If you feel you have answered correctly, please move on through the course.  The unit exams and the final exam are multiple-choice so you won’t experience this issue on the questions that are graded.  "Auto" and "automobile" are both correct. 

I hope this helps.  Please let me know if you have other questions.
