Answer:
First of all, you must decide which side of the argument you agree with. From there, you need to do research and find valuable sources as evidence (I see four have already been provided for you).
Explanation:
A clear claim could be "Bob Dylan qualifies for the award, as songwriting is a form of literature" or "American singer and songwriter, Bob Dylan, should not have received the award, as his career is not based in literature." A logical reason for disagreeing could be that he is not an author, and you don't agree musicians should count. On the other hand, one for agreeing would be that Bob Dylan is a writer, regardless of whether it is for musical purposes, and therefore, qualifies. When looking for sources, always try to stick to ".org," ".gov," or ".edu," as well as one's the have credited authors. Furthermore, Thesaurus.com is a great website to utilize for word choice, as is Dictionary.com.
