When comparing an author’s purpose across texts on the same topic, what is a key step?

• A. Assume all authors share the same purpose.
• B. Evaluate which text is longer to decide purpose.
• C. Determine each author's aim and the strategies used; compare how arguments, evidence, and tone differ.
• D. Only examine the conclusions drawn, ignoring methods.

Answer: (C)

When comparing authors’ purposes on the same topic, you focus on what each author is trying to achieve and the tools they use to get there. Identify each author’s aim, then look at the strategies they employ—how they build their argument, what kinds of evidence they use, how they structure information, and the tone they adopt. Compare how these elements come together in each text: what is emphasized, how the evidence is framed, and how the tone influences the reader. This helps you see how purpose shapes reasoning and presentation, revealing why texts on the same topic can take different angles.

Avoid assuming all authors have the same purpose, as that ignores how context and perspective shape writing. Length isn’t a reliable indicator of purpose, and focusing only on conclusions misses the methods that reveal why and how the arguments work.
