Read the passage from Sugar Changed the World. Cutting cane was hard work, but it was nothing like what came next: Piles of freshly cut cane had to be fed into the ever-turning mill wheels, until they were completely crushed. The owners insisted that during the work hours the grinding never stop, no matter what. The mills were most often tended by women who were doing dangerous work while getting almost no rest. That was a very bad combination. An ax was often propped up near the rollers so if a slave closed her eyes for a second while pushing the cane, her arm could be hacked off before she was pulled through the merciless grinders. Guests at sugar plantations often remarked on how many one-armed people they saw. How do the authors support their claim and purpose with their choice of words?
