Lesson 1 in preverbs2
Very frustrating lesson, with several mistakes. The only way to get through lesson is to provide incorrect answers. Someone needs to check and correct!
We are beta-testing ... you just did check the lesson. Did you document it for the developers?
Every time you run across a translation that looks wrong to you, hit the "Report a problem" button at the bottom.
I haven't gotten that far yet. Best bet is for you to go through and do the lesson again, flagging each issue you find; otherwise, the people working on the course will never know.
The whole "Preverbs 2" section is in a very rough state, and right now entails less learning the language than memorizing which form of the answer will be accepted, but we improve it as we go through.
