ead the passage from Sugar Changed the World. Eventually, I visited Guyana to find out the fate of our house. As our car passed
old sugar estates, and I saw the palm trees bending against the wide sky, the lush cane growing in thick, shiny rows, the villages, which were really parcels of land surrounding the important estates, I realized that sugar had been the entire reason for this country's existence. Every now and then an old boiling house—where the cane is processed into crystals, molasses, and rum—would show itself on the flat landscape, cropping up like a hulking ghost. How do the details about Guyana reveal the author’s purpose?
The author presents characteristics of Guyana's desolate and dismal landscape as a means to appeal to those who depended on the sugar production business in order to maintain themselves economically, and thus, demonstrating the importance of sugar. The whole purpose of the passage is to provide ethical evidence from the sugar scheme's current situation, presenting information about the moral consequences of this business' downfall; in this case, the economic backlash in the country of Guyana.
Use of subordinate clauses is more of a grammatical thing, and if the writer is not sure if a sentence is correct he/she may ask a peer reviewer to edit or comment on it. However, the body of the essay is a standard for every essay assigned and it should be much easier for the writer to tell if he/she is following the rules.
