When comparing two texts, how do authors' purposes shape their arguments?

• A. Purposes are identical across texts.
• B. Purposes only affect grammar.
• C. Purposes do not influence argument structure.
• D. Different purposes lead to different emphasis, evidence, and rhetoric.

Answer: (D)

Different purposes shape what the author highlights, what evidence they bring in, and the rhetoric they use to build an argument. If a text aims to persuade, it will emphasize certain claims, tug at emotions, and use persuasive techniques to sway the reader. If a text aims to inform, it will present facts in a clear, balanced way with neutral language and a straightforward structure. When you compare texts, you’ll notice those differences in emphasis, evidence choices, and style, which come directly from the authors’ different aims. That’s why this option is the best: different purposes lead to different emphasis, evidence, and rhetoric. Purposes aren’t identical across texts, and they influence more than just grammar or surface features—they shape how the argument is constructed.
