Question

read the passage from sugar changed the world. the diamond and the house: two family treasures, two parts of the story of sugar. we realized that our two family stories—marinas great - grandparents, brought to guyana to replace slaves, and marcs aunts grandfather, helping to refine an alternative to that same sugar—were just the beginning of a much larger story about a remarkable substance. it is a story of the movement of millions of people, of fortunes made and lost, of brutality and delight—all because of tiny crystals stirred into our coffee, twirled on top of a cake. sugar, we began to see, changed the world. what is the purpose of this passage? to explain who marina and marc are to link the authors families to sugar to explore the history of guyana to show what sugar is used for

Explanation:

The passage starts by introducing two family treasures (diamond and house) related to the story of sugar, then shares the authors' family stories (Marina's great - grandparents and Marc's aunt's grandfather) connected to sugar, and then leads to the idea that these family stories are part of a larger story about sugar changing the world. Option A is incorrect as the passage isn't mainly about explaining who Marina and Marc are. Option C is incorrect because the passage isn't focused on exploring Guyana's history; Guyana is just part of Marina's family story. Option D is incorrect as the passage doesn't focus on showing sugar's uses. The passage's main purpose is to link the authors' families to sugar and then introduce the larger story of sugar's impact.

Answer:

to link the authors' families to sugar
