For example, a sentence of "It is a fact that most arguments must try to convince readers, that is the audience, that the arguments are true." may be expressed more concisely as "Most arguments must demonstrate their truth to readers." the observations that the statement is a fact and that readers are its audience are redundant, and it is unnecessary to repeat the word "arguments" in the sentence.Program for Writing and Rhetoric, University of Colorado at Boulder.

""It is a fact that most arguments must try to convince readers, that is the audience, that the arguments are true." Notice the beginning of the sentence: "it is a fact that" doesn't say much; if something is a fact, just present it. So begin the sentence with "most arguments..." and turn to the next bit of overlap. Look at "readers, that is the audience"; the redundancy can be reduced to "readers" or "audience." Now we have "Most arguments must try to convince readers that the arguments are true." Let's get rid of one of the "arguments" to produce "Most arguments must demonstrate (their) truth to readers," or a similarly straightforward expression."
