On the sentence structures that you were supposed to draw for parts of homeworks 2 and 3, I had you number the nodes. But, just to clarify: there’s no secret, magic, or rules behind my choice of what number to assign to which node. I generally started from 1, and I started at the bottom, but you can number your nodes however you want, the only thing the number is there for is as a way to identify which node you’re talking about when you compute the meanings.
