The Tricky Grammar Test

In the immortal words of Samuel L. Jackson: "English, motherf****r: do you speak it?"

This test is hard if you don't have a firm grasp on American English grammar. You've been warned.

So, you've spelled "there," "their," and "they're" correctly since you learned to write. OKCupid test-makers have proclaimed you an "English Genius." You don't even end sentences with prepositions when you speak.

But could you pass a basic college grammar class?

Update 5-15-09: I corrected one question of the test which incorrectly awarded a point for a wrong answer, yet awarded nothing for the right answer. I know: I suck.
