"Prague has a million inhabitants." should be an acceptable and available answer.
I remember doing so. I will note whether I report, in future comments. Thanks for the reminder. Anyone reading this, if you agree, report too. It wil speed up recovery, I hope.

At least you won't get nagged by me about this anymore... ;-)
(I just tend to mention this a lot, since many people don't realize that that's how the course is improved. Those messages go straight to the course contributors, whereas it's "50/60" (to use a Finnish expression) whether they see these discussions or not.)
You can report a type by marking it as "something else went wrong" and in the discuss add a comment like :
"Reported: "xxx xx x" is marked as a typo, while it should not be considered a typo."
In this respect it is noteworthy to tell the language moderator whether this is about the menu or free typing. When I started I always used the menu. Since I have discovered free typing I don't use the menu anymore.
