The instructions for homework #6 got a little bit mixed up with respect to the numbering. What you’re being asked to do is draw three trees, one tree each for (1), (2), and (3), following the example given for (4).

So, in other words, follow the spirit and not the letter of the instructions. I’ll still take off points if no tree is drawn for sentence (1), even though you weren’t specifically told to draw a tree for it. 🙂

(This happened because in my original draft of this homework, the example came before the sentences for you to draw, and so was “(1)”, and then I added a third sentence after I wrote out the instructions and failed to mention it in the directions.)
