Set 7: Text Structure (Advanced)

Explanation

Answer: D

PASSAGE

The Heisenberg Uncertainty Principle asserts a fundamental limit to precision: one cannot simultaneously know the exact position and momentum of a particle. This is not a measurement error, but an intrinsic property of the wave-like nature of matter.

Which choice best describes the distinction made in the text?

A. It explains why our tools are broken.
B. It argues that particles don't exist.
C. It describes the cost of scientific equipment.
D. It clarifies that the limitation is ontological (nature of being) rather than technological.✓ Correct

Detailed Answer Explanation

This question tests your understanding of how the text is organized. Distinction: 'Not measurement error' (tech) but 'intrinsic property' (ontological). 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:

• "not a measurement error"

• "intrinsic property"

Why others are wrong: A (Explicitly says not error.), C (No cost.), B (Matter exists.).
