foreign language grammar lesson? Really?

Makes me realise just how much of my schooling I have forgotten. I got the simplest group, I failed badly on the other three. The answers highlighted much of the lessons I have lost. Mea Culpa, previously I would have aced this, now I know for sure I have lost knowledge to lack of practice. Thanks (but not thanks) to Mme Green for reminding me to not only think, but remember my education.
