Well i will write a sentence and the analysis of that sentence so please give me some opinions about that analysis because i find it hard to understand.(it was one of the tasks at my final exam,and almost everybody failed)


Since I have been trying to convince you that there is a language instinct but would certainly forgive you (if you would rather believe Darwin than believe me), I would also like to convince you that you need not make that choice.
