Explanation
PASSAGE
Quantum entanglement challenges our understanding of locality. If two particles are entangled, a change in one instantly affects the other, regardless of distance. Einstein derided this as 'spooky action at a distance,' yet experiments have repeatedly confirmed it.
Which choice best describes the function of the underlined sentence?
A. It introduces a historical skepticism that was later disproven by evidence.✓ Correct
B. It proves that the theory is scientifically impossible.
C. It explains the mathematical formula for entanglement.
D. It supports the idea that locality is absolute.
Detailed Explanation
Historical skepticism: Einstein's derision. Disproven: Experiments confirmed it.
Key Evidence:
• "Einstein derided"
• "yet experiments ... confirmed"
Why others are wrong: B (It was confirmed.), C (No math.), D (Refutes locality.).
