PASSAGE

Renewable energy sources are infinite. Solar power, for example, comes from the sun, which will shine for billions of years. Fossil fuels, in contrast, take millions of years to form and are finite.

Which choice best describes the function of the third sentence?

A. It describes the formation of the earth.
B. It argues that we should use more oil.
C. It contrasts the renewable source mentioned with a non-renewable one.✓ Correct
D. It explains how the sun works.

Detailed Answer Explanation

This question tests your understanding of how the text is organized. Sentence 2 uses Solar (infinite) ex. Sentence 3 uses Fossil Fuels (finite) to contrast. Authors structure their writing purposefully to guide readers through their ideas. Identify the organizational pattern (cause-effect, compare-contrast, problem-solution) and how each part contributes to the whole. Authors choose organizational patterns deliberately to enhance their message. Recognizing whether a text uses chronological order, cause-effect, compare-contrast, or problem-solution helps you understand the author's purpose and follow the logic.

Key Evidence:

• "in contrast"

• "finite"

Why others are wrong: A (No geology.), B (It highlights they run out.), D (No physics.).
