Set 1: Inferences (Advanced)

Explanation

Answer: C

PASSAGE

Quantum mechanics describes particles as existing in 'superposition'—multiple states simultaneously—until measured. The Copenhagen interpretation holds that measurement causes 'wave function collapse' into a definite state. Alternative interpretations, like Many-Worlds, propose that all possible outcomes occur in branching universes. No experiment currently distinguishes between these interpretations.

What does the debate suggest about the relationship between physics and philosophy?

A. Quantum mechanics has been definitively explained.
B. Physics provides a single, unambiguous account of reality.
C. Empirically equivalent theories may require philosophical choices about interpretation.✓ Correct
D. All physicists agree on the Many-Worlds interpretation.

Detailed Explanation

This question asks you to draw a logical conclusion from the text. 'No experiment distinguishes' between interpretations = same data, different philosophies of what it means. A valid inference must be supported by evidence in the passage, even if not stated directly. Look for clues in the text that strongly suggest the answer. Avoid conclusions that require assumptions beyond what's written. Valid inferences are strongly supported by multiple pieces of evidence in the text. Be cautious of choices that go too far beyond what the passage actually states. The best inference is the one most directly supported by textual evidence.

Key Evidence:

• "no experiment currently distinguishes between these interpretations"

Why others are wrong: A (Interpretations are still debated.), B (Multiple interpretations exist.), D (Copenhagen is also mentioned as an option.).
