PASSAGE
Ideally, a scientific theory is testable and falsifiable. String theory, while elegant mathematically, deals with scales so small they cannot currently be observed. This has led some to question its validity as science.
Which choice best describes the relationship between the first and second sentences?
A. The second sentence presents a case that conflicts with the criteria in the first.✓ Correct
B. The second sentence provides proof for the theory in the first.
C. The two sentences describe unrelated fields of study.
D. The first sentence defines the term used in the second.
Detailed Explanation
Criteria: Testable. Case: String theory (cannot be observed/tested). This is a conflict.
Key Evidence:
• "testable"
• "cannot currently be observed"
Why others are wrong: B (Disputes it.), C (Related.), D (It applies criteria, doesn't just define.).
