The measurement problem in quantum mechanics arises because the theory describes systems as existing in superpositions until measured, whereupon they 'collapse' to definite states. But what counts as a measurement? Consciousness causing collapse seems unscientific; defining measurement physically risks circularity. The many-worlds interpretation avoids collapse by claiming all possibilities are realized in branching universes—mathematically elegant but ontologically extravagant. Each interpretation solves problems while creating others.

It can be inferred from the text that

A

quantum mechanics has no interpretive challenges

B

the many-worlds interpretation has no costs

C

resolving fundamental problems in physics may require accepting commitments that create their own difficulties

D

consciousness-based interpretations are universally accepted

Correct Answer: C

Choice C is the best answer. Every interpretation "solves problems while creating others."

  1. Context clues: Consciousness seems unscientific; physical definitions risk circularity; many-worlds is ontologically extravagant.
  2. Meaning: No cost-free solution exists.
  3. Verify: "Each interpretation solves problems while creating others" states this explicitly.

đź’ˇ Strategy: When every solution introduces new problems, infer trade-offs are inescapable.

Choice A is incorrect because the measurement problem is a significant challenge. Choice B is incorrect because many-worlds is "ontologically extravagant." Choice D is incorrect because consciousness-based collapse "seems unscientific."
