I missed 3 out of the 22 questions, which gave me a not so stellar 86% on the quiz. After wondering for a brief period if somehow the site didn’t save my correct answers properly, I determined that the mistakes were mine.
Anyway, now I’m pretty sure I know even better the difference between derivations and inflections. I’m still having issues with agglutinating versus inflectional languages though. The third question I missed was due to lazy reading. I should have caught that one because I caught another one that was similar. I was just too lazy to go proofread the quiz another time.
