Set 7: Text Structure
Explanation
PASSAGE
Mitochondrial DNA is inherited maternally. This unique inheritance pattern allows geneticists to trace maternal lineages back thousands of years to a theoretical 'Mitochondrial Eve'.
Which choice best describes the utility of the biological mechanism?
Detailed Answer Explanation
This question tests your understanding of how the text is organized. Mechanism: Maternal inheritance. Utility: Trace lineages/History. 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:
• "inherited maternally"
• "allows ... to trace ... back"
Why others are wrong: A (Mitochondrial only.), B (Tracing, not cloning.), D (No survival data.).
