Hen and shi

I have two questions in this grammar section. ‘She’s cool’ and “He’s handsome’. Both cool and handsome are adjectives. So I should select ‘hen’ but it says incorrect. If I select “shi” it says incorrect.

So it seems there is no correct answer.

It must be a bug or a glitch, did this just happen once?

It happens every time. I’ve been stuck at this lesson for two weeks now.

Memrise has been having a lot of bugs. Here is some info about Memrise’s bugs recently.
