Explanation
PASSAGE
LIGO detected gravitational waves in 2015, confirming Einstein's prediction. These ripples in spacetime, from merging black holes, opened a new window on the universe.
What did LIGO's detection confirm?
Detailed Explanation
This question requires you to identify evidence that supports a claim. 'Confirming Einstein's prediction.' The best evidence directly and explicitly supports the stated claim without requiring assumptions. Match specific textual details or data points to the claim being made. The correct answer provides clear, direct support. Strong evidence directly addresses the claim without requiring additional interpretation. When evaluating options, look for quotes or data that explicitly support the statement. Weak evidence may be tangentially related but doesn't provide direct proof.
Key Evidence:
• "LIGO detected gravitational waves in 2015, confirming Einstein's prediction"
Why others are wrong: A (This option is incorrect.), B (This option is incorrect.), C (This option is incorrect.).
