^Thanks a lot Sikorsky.

For 2), Can you explain the difference between “is” and “has been”?

And for 3), the question was an identifying errors question, with “have become” to supposedly be the error. I was thinking, because the sentence began with “While Dixon’s upbeat blues compositions helped,” would it make sense to use “became” to match the verb tenses?

Thanks again
