When you are considering (f) (postcards from Greece) and (h) (a book of postcards) in part 1, you ultimately want to conclude that these are constituents. And, furthermore, (f) should appear in the list for one of the meanings, and (h) should appear in the list for the other of the meanings, in part 2. This becomes important later on, particularly in part 5. So, I don’t want to keep you from being able to do part 5 just because something went haywire in part 1.
