Answer:
<em><u>Introduction, body, transitions, conclusion</u></em>
Explanation:
In an article or an essay, there are <u>essential elements</u> that must be outlined and included to have a cohesive, reliable and structured text.
These elements are the<u> introduction</u> (the purpose of the analysis, the main topic sentence), <u>the body</u> ( the paragraphs that cover the analysis), the <u>transitions</u> (connecting words that give consistency to the text), and <u>the conclusion</u> (final insightful remarks).
On an<u> outline skeleton</u>, sketching these elements can be helpful to envision a draft of the text and all the main points that are going to be covered in each element, resulting in a successful and valid piece of writing.
