Set 3: Cross-Text Connections

Explanation

Answer: A

PASSAGE

Text 1 Heisenberg's Uncertainty Principle is a fundamental limit in quantum mechanics. It states that certain pairs of physical properties, like position and momentum, cannot both be known to arbitrary precision. The more precisely you know one, the less precisely you know the other. Text 2 This is not a measurement error or a limitation of our tools. It is an intrinsic property of wavelike systems. Because particles have wave nature, they do not have a defined position and momentum simultaneously in the way classical objects do.

How does Text 2 clarify the source of the 'limit' mentioned in Text 1?

A. It defines it as an ontological feature of quantum reality (wave nature) rather than an epistemological failure (measurement).✓ Correct
B. It blames broken tools.
C. It says the limit does not exist.
D. It claims particles are not waves.

Detailed Explanation

Text 1: Limit on precision. Text 2: Not measurement error/Intrinsic property/Wave nature. Source: Nature of reality, not tools.

Key Evidence:

• "not a measurement error"

• "intrinsic property"

Why others are wrong: B (Explicitly denies.), C (Explains it.), D (Says they have wave nature.).
