Roland says that ruth crawford seeger was a modernist composer. clive says that she was a collector and arranger of american folksongs. who is correct?

I think that both Roland and Clive are correct.
Roland is correct when he said that Ruth Crawford Seeger was a modernist composer because she lived during the era of modernism and composed her own music during that time. However, Clive is also correct when he says that she was a collector and arranger of American folksongs because she did that for a period of time.

He developed the concept of linear perspective, and he had the ability to solve architectural problems using mathematics.
