The statement that best explains how the authors develop their claim across the two passages is:
Both passages use facts and details to support the claim that sugar workers in different places used music to express themselves and relieve the pressures of brutal work.
This interpretation aligns with the references in both passages to the cultural expressions and musical traditions (like jazz in Louisiana and holehole bushi in Hawaii) that emerged among sugar workers as a means of coping with their difficult lives and asserting their humanity.
