Good students are usually those who carry their books around with them and read a few pages at a time. Complex novels, in particular, should not be read in chunks. They expect specific answers handed to them. Their expectations are that there are concrete, specific, definitive replies to their questions. This is, after all, a course that is supposed to teach them about literature.
Great literature lends itself to ambiguity.
There are no definitive interpretations such that all future discussion is henceforth ended. There is always room for disagreement, even to the point of understanding that there may be multiple interpretations of the same work. These points are well illustrated by our reading of Wuthering Heights . Neither one is to be trusted. What truly happens in the novel is not to be revealed by an uncritical acceptance of these narrators' words.
