Detailed Answer Explanation

This question tests your understanding of how the text is organized. Analogy: Ghost. Why: Presence felt but never seen (Gravitational effects only). 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:

• "ghost"

• "felt but never seen"

Why others are wrong: B (It's dark/invisible.), A (Metaphor.), C (No ectoplasm.).
