Nice story! This story is similar to Cinderella's story, but what is the question?
Its what opens a story and establishes the context which gives the background information.
Whales migrate at different parts of the year for different reasons....
Something simple like that. A thesis statement is the main part of the paper and you should keep talking about it consistently through the writing....
Hope this helps!
Third Person omniscient means that the narrator can not only hear the protagonists thoughts but also everyone else. Therefore the story can be told from may different perspectives. Hope it helped :)
