Read the passage and study the image and caption from Sugar Changed the World.Caption: The first factories were places like this cotton mill in Manchester, England.All over England, in sooty cities such as Manchester and Liverpool, when the factory whistle blew, workers would set down their presses and file out to drink a quick cup of tea sweetened with sugar—usually dipping a piece of bread in the warm drink. Soon a smart manufacturer figured out that this break, and the need for a jolt of sweetness, was an opportunity. English workers were offered sugary cookies and candies—what we call today energy bars—that quick pick-me-up that helped workers to make it through their long shifts.Starting around 1800, sugar became the staple food that allowed the English factories—the most advanced economies in the world—to run. Sugar supplied the energy, the hint of nutrition, the sweet taste to go with the warmth of tea that even the poorest factory worker could look forward to. Sugar was a necessity.
