The Question 6.1 is:
All API versions should be considered stable. True or False?
I said "false" as alpha-versions are not considered stable. But that gets marked as "wrong". Why?
This would be a mistake. I will ask that the question be fixed. Thanks for reaching out and letting us know.
It seems that the tool we use shows the question marked properly as false. If you see this again would you please take a screen shot and share it with us as this would indicate a bug we would need to investigate.
Thank you again for reaching out.
