First, you can say that the choices are very alike and also very different. In the introduction paragraph start with:The story, "Elizabeth Baine's Compass and Torch", is very similar and also very different from the stories; "Colin Linden's Luck Charm", and "Bob Thurber's Cricket War."... (And so on). In the second paragraph start with: They are similar to each other because... (And so on). In the third paragraph start with: They are different from each other because... (And so on). In the concluding paragraph, sum everything up together.
