Mairs' essay is under copyright, but appears in many anthologies used in AP Language and Composition. It's an excellent example of personal writing and is especially useful to teach syntax. This quiz is a rigorous 36-item multiple choice and matching activity focusing on a variety of tools of language. I use it as a formative quiz but it could easily be adapted for summative evaluation. My students use their text with whatever annotations they produced.
