Query: And the answer is?

I purchased this workbook as a companion to the McDougal Littell Language Network set. It covers a lot of various activities and follows the text book beautifully...just one problem; there's no answer key. For the basic skills this isn't too much of a problem but when it comes to diagramming complex sentences and some of the punctuation assignments, a key is essential.
