Music historian: A newly discovered manuscript of symphonies attributed to the 18th-century composer Antonietta contains complex harmonic progressions previously thought to have been invented decades later. Chemical analysis definitively dates both the paper and the ink to the 1720s, during Antonietta's active years. Therefore, Antonietta pioneered these advanced harmonic progressions.
The argument above depends on the assumption that Antonietta did not simply transcribe the innovative compositions of an uncredited contemporary.
Answer: Answer
Answer
True. The statement identifies a necessary assumption required to logically link the physical existence of the manuscript to the claim that Antonietta originated the musical ideas.
The statement accurately identifies a necessary assumption. The argument jumps from the existence of a 1720s manuscript bearing Antonietta's name to the conclusion that she conceptually originated the music. For this conclusion to survive, one must assume she was the true creator. Using the Negation Test, if she were merely transcribing another composer's original work, she could not be considered the pioneer, and the argument collapses entirely. Thus, the assumption is necessary.
