I'm working with Lesson 5.9 All Important Keys (Part 2), and there seems to be an error in the lesson introduction. The lesson text is copied below:
Look at the correct ways of translating “to be” into French in the following contexts:
She is 20 = Age = Vous avez vingt ans
Shouldn't the French read "Elle a vingt ans"
Translating the Verb Etra

Yep. You are right, Diana.
The lesson needs an editor to take another look. It says it will introduce five ways to distinguish être and avoir.
Then, in Action Replay, it introduces Y, En, and Y+En.
What? They were not discussed above, and they are in other lessons, why were they put here?
Maybe a nice bold header for Avoir and another for Être.
Under each, include the phrases and audio samples that indicate each.
All the other material should be moved to another lesson including audio that doesn't support such as
Pas à pas

Salut tous les deux!
Thank you very much for pointing this out to us Diana, that is an embarrassing typo. We will look at getting that changed asap.
Keep up the good work!
