I want to know the answer to the following question:
Who said that Kanye West effectively led a new wave of artists that weren't only interested in rapping about gunplay or drug dealing?
All the background I'm provided with is that "The sales competition between rapper 50 Cent's Curtis and West's Graduation altered the direction of hip hop and helped pave the way for new rappers who did not follow the hardcore-gangster mold.". Is that enough to answer the question?
Answer: no
