Instruction: identify the assumptions that must hold for the statement to be valid, then choose the correct option.
Statement: The discovery of gravitational waves has provided strong evidence for Einstein's theory of general relativity, but it also opens up new possibilities for understanding the universe's most extreme phenomena, such as black holes and neutron stars.
Assumptions:
I. Gravitational waves offer new insights into the nature of the universe.
II. Einstein's theory of general relativity has been conclusively proven by the discovery of gravitational waves.
III. The study of gravitational waves will lead to new breakthroughs in astrophysics.
Show answer & explanation
Correct answer: C
Explanation
Answer: Only Assumption I is implicit
Analysis:
Assumption I — 'Gravitational waves offer new insights into the nature of the universe.'
This directly follows from the statement's claim that the discovery 'opens up new possibilities for understanding the universe's most extreme phenomena.' This is implicit in the statement. ✓
Assumption II — 'Einstein's theory of general relativity has been conclusively proven...'
The statement says gravitational waves provide 'strong evidence for' the theory — this is far weaker than 'conclusively proven.' Proof and evidence are different things; a theory can never truly be 'proven' in science, only supported. This assumption overstates what the statement says and is not implicit. ✗
Assumption III — 'The study of gravitational waves will lead to new breakthroughs in astrophysics.'
The statement only says it 'opens up new possibilities for understanding' — it doesn't guarantee or assume future breakthroughs will occur. This is a prediction about the future that goes beyond what's stated, so it's not implicit. ✗
Conclusion: Only Assumption I is valid/implicit in the statement.
