the format of a research paper should include all of the following except which one? abstract a works cited…

Brief Explanations:

An abstract is a summary, a Works - Cited page lists sources, indenting paragraphs and having header information are formatting details. All are common in research papers. There is no indication that any of these are incorrect, but if we consider that the first three are content - related elements and the last two are formatting elements, and we assume the question is looking for something that is not a core content element, the formatting - only elements are less central. However, all of these are common in research paper format. If we must choose, "Indent the first line of each paragraph one half - inch from the left margin" is more of a specific formatting instruction rather than a content - based component like the others.

Answer:

Indent the first line of each paragraph one half - inch from the left margin
