It’s just been called to my attention that homework #6 has a typo on it, in the example tree. The example is passive. Little v should not have a [uN*] feature on it. An unfortunate copy & paste error on my part.

You can download homework #6, v1.1, containing the corrected tree to take a look, though the change is small enough you might as well just make the change on your hardcopy. It’s also linked into the schedule page.

(Incidentally, we’ll talk about the passive at the beginning next time, we haven’t really talked about it yet. But, when we do, it should become clear that the original homework handout was in error.)
