AP CS Principles - Activity Solutions?

Hi -
I am a verified teacher - but I can’t find all the solutions to the Activity worksheets, for example in Unit 9 , Lesson 4: Exploring Two Columns - I don’t see the solutions.

Similarly I can’t find the solutions to the other activities.
Is there a convenient way for teachers to all the solution keys?

I responded on the other thread where you posed a similar question.
