It was just brought to my attention that there is a small error on the key for homework #4.

It’s on the very last sentence of the homework: John does bind him and so it should have been underlined.

For completeness, I’ve replaced the key online, although this is the only change.

Addendum: It appears that some people lost a half-point for underlining John, even though it should have been underlined. You can have that half-point back, just bring your homework to class and I’ll fix it. And if you didn’t underline John and didn’t lose a half-point, you can feel free to take a half-point off your score (but don’t bother telling me about it).
