Translation:She is waking up.
The drop-down says "He/she wakes up." It did not accept "She wakes up" for the answer. It should.
That's essentially the same, just less usual in contemporary spoken English.
Don't worry, that's coming in the course, but for a sneak peek:
Aliamka = He woke up / awoke
Ameamka = He has woken up / awoken
