Which statement best describes the role of literacy in developing disciplinary thinking?

• A. Reading only helps memorize facts.
• B. Literacy is irrelevant to argumentation in science.
• C. Language supports reasoning, explaining concepts, and evaluating evidence across subjects.
• D. Spelling accuracy is the sole literacy goal.

Answer: (C)

Literacy is a tool for thinking across disciplines. It lets you reason through ideas, explain concepts in your own words, and evaluate evidence from different sources. When you read a science text, you aren’t just absorbing facts—you’re tracing a line of reasoning, noting how data support a claim, and deciding whether the evidence is strong enough. When you write or discuss in math, you justify steps, explain why a method works, and make your reasoning clear to others. In history or social studies, literacy helps you analyze sources, compare perspectives, and build coherent arguments grounded in evidence. This broad view of literacy as a practice that supports reasoning, explanation, and evidence evaluation across subjects is what makes it essential for developing disciplinary thinking.

That’s why this statement is the best description: language supports reasoning, explaining concepts, and evaluating evidence across subjects. It captures how literacy enables the core activities of thinking in each discipline. Other views miss important parts: reading isn’t only about memorizing facts, argumentation matters in science and beyond, and spelling is just one small piece of literacy, not the entire goal.
