Set 5: Cross-Text Connections

Explanation

Answer: A

PASSAGE

Text 1 String theory attempts to reconcile general relativity (gravity) and quantum mechanics. It proposes that the fundamental constituents of the universe are not point-like particles, but one-dimensional 'strings' vibrating at specific frequencies. Text 2 A major criticism of string theory is its lack of testability. The theory requires extra dimensions that are compacted at scales too small for current technology to probe. Without experimental verification, some physicists argue it belongs to philosophy, not science.

What is the primary epistemological challenge to the theory presented in Text 2?

A. Its unfalsifiability due to technological limitations.✓ Correct
B. Its math is too simple.
C. It contradicts gravity.
D. It has too few dimensions.

Detailed Explanation

Text 1: Definition. Text 2: Criticism = Lack of testability/Too small to probe. Challenge: Cannot be proven/disproven (Unfalsifiability).

Key Evidence:

• "lack of testability"

• "without experimental verification"

Why others are wrong: B (Complex.), C (Reconciles it.), D (Extra dimensions.).
