I don't understand this part of the lesson.

Harold has just finished his tour, and met the staff of the Delavigne Corporation.
Now, how do you feel after meeting everyone? .......multiple choice list....
(There are no incorrect answers! We just want to hear your opinion!)

If there are no incorrect answers why ask my opinion with a multiple choice list?
I chose the last answer of the list: ==>...."I
am not entirely convinced by this question"

I also did not understand the answer of the correction below:
(There are no incorrect answers! We just want to hear your opinion!)
am not entirely convinced by this question.: We understand completely, sir or madam. Could you please summarize your reservations into one word or less and include them in a polite, well-formulated comment using the field at the bottom of this lesson? Thanks so much for your understanding. Toodles!

If anyone can explain ? Thank you !
