I recieved a DBQ today and I am having trouble writing it. Could someone give me some advice or analyzations of the documents please?

Prompt:
in 1858 Senator William Henry Seward examined the sources of the conflicts between North and South. Some people thought the sectional conflict was "accidental, unnecessary, the work of interested or fanatical agitators, and therefore ephemeral." he believed these people were wrong. The roots of the conflict went far deeper. "It is an irrepressible conflict," Seward declared, "between opposing and enduring forces." using the documents provided plus outside information, analyze the validity of this statement.
