Read the passage from Sugar Changed the World. In one part of Russia, though, the nobles who owned the land were interested in trying out new tools, new equipment, and new ideas about how to improve the soil. This area was in the northern Ukraine just crossing into the Russian regions of Voronigh and Hurst. When word of the breakthrough in making sugar reached the landowners in that one more advanced part of Russia, they knew just what to do: plant beets. Cane sugar had brought millions of Africans into slavery, then helped foster the movement to abolish the slave trade. In Cuba large-scale sugar planting began in the 1800s, brought by new owners interested in using modern technology. Some of these planters led the way in freeing Cuban slaves. Now beet sugar set an example of modern farming that helped convince Russian nobles that it was time to free their millions of serfs. And that is precisely where Marc's family story begins—with Nina's grandfather, the serf who bought his freedom from figuring out how to color beet sugar. What is the purpose of this passage? to explain the new technologies farmers used in the 1800s to connect a period of Russian history with the history of sugar to explain to readers how enslaved Africans differed from Russian serfs to give background information about the origins of cane sugar
