Jorge: You won' t be able to write well about the rock music of the 1960s, since you were just an infant then. Rock music of the 1960s was created by and for people who were then in their teens and early twenties. Ruth: Your reasoning is absurd. There are living writers who write well about ancient Roman culture, even though those writers are obviously not a part of ancient Roman culture.
The statement 'whether people who are not now in their teens or early twenties can write well about the rock music of the 1960s' most accurately represents what is at issue between Jorge and Ruth.
