Rochelle is writing a research paper about the reasons whales migrate. which is the most appropriate thesis statement for her paper?

When brainstorming before the creation of a thesis statement, one thing to keep in mind is that thesis statements are basically mini outlines that tell readers the topics of the body paragraphs (content) in the exact order in which they will appear in the paper.  That said, let’s say Rochelle is going to be discussing three reasons whales migrate—REASON 1, REASON 2, and REASON 3.  That said, one potential thesis statement could be the following:

Even though whales may migrate for a myriad of reasons, the reasons of REASON 1, REASON 2, and REASON 3, are the main reasons for which the majority of whales migrate.

It’s important to always have body content appear in the identical order in which it appears in the thesis statement and to only include content that is mentioned or alluded to within the thesis statement because anything that appears within a paper that is not will be considered off topic.  

where is the passage?
