Having completed a first supervision on this examples sheet, I have now made some corrections to the questions, and made some changes of wording that I think will help.
I have also taken a hard question from sheet 3 and moved it to the end, as question #11. It is certainly "starred", but might be interesting to discuss, as it points up the duality of the questions of controllability and observability.
