Select the more effective sentence: 1) Classical music is much different from big band music. 2) Classical music is much better than big band music.

I would say the first one: "Classical music is much different from big band music."

I've learned that effective sentences have to be grammatically and factually correct, meaning the sentence can't be an opinion. Therefore, the second sentence can't be the answer because it is an opinion statement.

hope this helps

we need the passage first

the correct answer would be:  

a. adverb phrase
