In the sentence "American music from 1900 to 1950 was notably for its harmony and melody, which served the public well," there is indeed one mistake. The option with the correct form is:
c) American music from 1900 to 1950 was notable for its harmony and melody, which served the public well.
- Let's focus on the first part of the sentence first, which is "American music from 1900 to 1950 was notably for its harmony and melody."
- The complete subject of that part is "American music from 1900 to 1950."
- That subject is followed by a linking verb, which is the past form of to be, "was".
- Linking verbs are usually <u>not followed by adverbs</u>. They are followed by adjectives that modify the subject.
- "Notably" is an adverb. We must change it into an adjective for the sentence to be correct. The equivalent adjective is "notable".
- The correct sentence would then be: "American music from 1900 to 1950 was notable for its harmony and melody."
- Now, let's take a look at the second part of the sentence, which is "which served the public well."
- Here, we also have an adverb, "well", following a verb, "served".
- But, in this case, it is<u> not wrong</u> to use to adverb. "Served" is not a linking verb. It is an action verb, and it can be modified by the adverb "well".
- Therefore, there is <u>no mistake</u> in the second part of the sentence.
With the information above in mind, we can conclude that the correct option is letter C. American music from 1900 to 1950 was notable for its harmony and melody, which served the public well.
