The job is to decide, by careful reading and reflection, where in a story these four excerpts would be. As you read each one, think to yourself, 'Does this sound like the opening of a story? the middle? the most exciting moment? the very end?'
It's up to you to decide. I am assuming your teacher has taught you the various stages of plot development. Get out your notes and take a look.
All best wishes,
