Incorrect exercise: [courseId=grammar-intro_eng][lessonNumber=1][exerciseId=3944]

Description

The lesson said that, to be bridi, the jufra needs to have "one or more sumti". I assumed that means "at least one".
This exercise shows that that is... false?

The next lesson have a paragraph explaining how a bridi can have a selbri only with no places filled at all (i.e. implicitly filled by zo'e). But I do agree that the lesson at its current state would be misleading. Moving that paragraph to the first lesson would help solve the problem, but I am afraid that it would make the first lesson too long for beginners...
