Which choice best describes the ethical expansion?

A. It lists diseases.
B. It argues that vaccines should be mandatory.
C. It explains how to make a vaccine.
D. It moves from individual benefit to collective responsibility.✓ Correct

Detailed Answer Explanation

This question tests your understanding of how the text is organized. Mechanism: Herd immunity. Implication: Not just personal choice -> Public service (Collective responsibility). 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:

• "protects the vulnerable"

• "not just a personal ... choice"

• "public service"

Why others are wrong: A (No list.), B (Implies duty, but focus is on the concept.), C (No manufacturing.).
