Set 1: Central Ideas (Intermediate)

Explanation

Answer: B

PASSAGE

The following text outlines the Heisenberg Uncertainty Principle. In quantum mechanics, the Heisenberg uncertainty principle states that it is impossible to simultaneously measure the position and momentum of a particle with absolute precision. The more precisely one property is measured, the less precisely the other can be known. This is not due to technological limitations, but rather a fundamental property of nature itself, arising from the wave-particle duality of matter.

What does the text imply about the limitations of measurement in quantum mechanics?

A. They are temporary hurdles that better technology will eventually overcome
B. They only apply to particles moving at the speed of light✓ Correct
C. They are inherent characteristics of nature, independent of equipment quality
D. They prove that quantum mechanics is a flawed theory

Detailed Explanation

Choice C is correct. The text emphasizes that the uncertainty is 'not due to technological limitations, but rather a fundamental property of nature.'

Key Evidence:

• "not due to technological limitations"

• "fundamental property of nature"

Why others are wrong: A (Opposite (explicitly denied by the text)), B (Not mentioned), D (Unsubstantiated inference).
