In the passage, the authors claim that the rise of new sweeteners helped end the practice of slavery. They provide empirical evidence to support this idea. The evidence includes a description of advances in sweetener production during the 1800s. For example, percentages show a dramatic increase in sugar made from beets from 1854 to 1899. This information is verifiable, and it is relevant because it coincides with the end of slavery in many parts of the world. For these reasons, the authors’ evidence is effective because it provides reliable information that bolsters their claim and purpose.
