Here’s a handout which (i) summarizes some of the key concepts we’ve introduced in class so far, and (ii) summarizes our discussion of entailments, as well as our tests for identifying them. Since these tests do not appear anywhere in your readings, I thought that this would be a useful addition to your notes. You should certainly feel free to refer to the handout when completing your homework–note in particular that the first problem asks you to use the entailment tests to justify your answers.
