Monarch Butterflies adapted from US Forest Service

The annual migration of North America's monarch butterfly is a unique and amazing phenomenon. The monarch is the only butterfly known to make a two-way migration as birds do. Unlike other butterflies that can overwinter as larvae, pupae, or even as adults in some species, monarchs cannot survive the cold winters of northern climates. Using environmental cues, the monarchs know when it is time to travel south for the winter. Monarchs use a combination of air currents and thermals to travel long distances. Some fly as far as 3,000 miles to reach their winter home! Monarchs in Eastern North America have a second home in the Sierra Madre Mountains of Mexico. Monarchs in Western North America winter in California.

Read the passage, then answer the question that follows. no one could have seen it at the time, but the invention of beet sugar was not just a challenge to cane. it was a hint—just a glimpse, like a twist that comes about two thirds of the way through a movie—that the end of the age of sugar was in sight. for beet sugar showed that in order to create that perfect sweetness you did not need slaves, you did not need plantations, in fact you did not even need cane. beet sugar was a foreshadowing of what we have today: the age of science, in which sweetness is a product of chemistry, not whips. in 1854 only 11 percent of world sugar production came from beets. by 1899 the percentage had risen to about 65 percent. and beet sugar was just the first challenge to cane. by 1879 chemists discovered saccharine—a laboratory-created substance that is several hundred times sweeter than natural sugar. today the sweeteners used in the foods you eat may come from corn (high-fructose corn syrup), from fruit (fructose), or directly from the lab (for example, aspartame, invented in 1965, or sucralose—splenda—created in 1976). brazil is the land that imported more africans than any other to work on sugar plantations, and in brazil the soil is still perfect for sugar. cane grows in brazil today, but not always for sugar. instead, cane is often used to create ethanol, much as corn farmers in america now convert their harvest into fuel. –sugar changed the world, marc aronson and marina budhos how does this passage support the claim that sugar was tied to the struggle for freedom? it shows that the invention of beet sugar created competition for cane sugar. it shows that technology had a role in changing how we sweeten our foods. it shows that the beet sugar trade provided jobs for formerly enslaved workers. it shows that sweeteners did not need to be the product of sugar plantations and slavery.
