"8:45 in the morning."
How long has this course been out, and the hover-over hints are still missing? I report it every time I see it, but I have yet to see a single one of my reports about these hints being wrong or missing, acted on.
Are any of the course contributors even checking the reports about the hover-over hints or are they focusing exclusively on the sentence translations?
I think it would improve the course significantly if there were better hover-over hints, especially in the earlier exercises or sections, ones likely to have the largest number of beginners practicing them repeatedly.
