Self-study
Musicologist: Support Classification of a musical instrument depends on the mechanical action through which it produces music. ██ ███ █████ ██ ████████ ██████ █ ██████████ ███████████ ███ █ ████████ ███████████ ████ ██████ ███ █████████ ██ ███ ███████ ███████ ██ ████ █████ ███ ██████ ███ ███████ ███ ██████ ██ ███████ ██ ███ ██████ ██ ████████
Summarize Argument
The piano has been correctly classified as a percussion instrument. Why? Because classification is based on the action that produces sound, and it is percussion that produces sound in pianos.
Identify Conclusion
The conclusion approves of the piano’s current categorization: “the piano is properly called a percussion instrument, not a stringed instrument.”

Which one of the following ████ ██████████ █████████ ███ ████ ██████████ ██ ███ ██████████████ █████████
a
Musical instruments should ██ ██████████ █████████ ██ ███ ██████████ ███████ ███████ █████ ████ ███████ ██████
This is a modified version of the musicologist’s premise. However, the musicologist doesn’t actually give her opinion on whether this should be the method of classification; she’s only evaluating the piano using this method. It’s possible that her approval of the piano’s classification could be based on correct application of the rule, not approval of the rule itself.
b
Musical instruments should ███ ██ ██████████ █████ ██ ███ ███ █████████ ████████ ████ █████
This idea is not discussed in the stimulus.
c
Some people classify ███ █████ ██ █ ████████ ██████████ ███████ ██ ███ ███ ███ █████ ████████ ██████
The musicologist does not make a claim about whether or why some people classify the piano as a stringed instrument.
d
The piano should ██ ██████████ ██ █ ████████ ██████████ ██████ ████ ██ █ ██████████ ███████████
(D) has reversed the musicologist’s conclusion. She believes that the piano is correctly classified as a percussion instrument rather than a stringed instrument, not the other way around.
e
It is correct ██ ████████ ███ █████ ██ █ ██████████ ██████████ ██████ ████ ██ █ ████████ ███████████
This rephrases the conclusion.
