Set 5: Command of Evidence
Explanation
PASSAGE
Jazz originated in New Orleans in the late 19th and early 20th centuries, blending African rhythms, blues, and European harmonies. Key to jazz is improvisation—musicians spontaneously create melodies within a given harmonic structure. This makes each performance unique.
What makes jazz performances 'unique,' according to the text?
Detailed Explanation
This question requires you to identify evidence that supports a claim. The text says 'musicians spontaneously create melodies' through improvisation, making 'each performance unique.' 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:
• "improvisation"
• "spontaneously create melodies"
• "each performance unique"
Why others are wrong: B (This option is incorrect.), C (They improvise 'within a given harmonic structure.'), D (They play songs, but improvise within them.).
