Which is a component of an effective paragraph in the body of a research report? author’s insights interwoven with facts no expert testimony informal language vague facts and details

The correct answer is author’s insights interwoven with facts.

In order to develop an effective body paragraph we need an author's insight that can be represented by a topic sentence, that gives an interpretation of a fact, an idea based on your sources. In well-developed body paragraphs, you have to provide a form of evidence, in a research report would be facts. Not only present them but make sure to interpret them for your readers.

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.
