A writer is working on a research paper in which he argues in favor of warning labels on packs of cigarettes. One of the paragraphs in his paper reads: The article "Cigarette Warning Labels: Should the U.S. Government Mandate Large, Graphic Warning Labels on Cigarette Packaging?" provides evidence suggesting that cigarette warning labels successfully deter smoking: "Geoff Fong, a researcher at the University of Waterloo in Ontario, Canada, who has studied cigarette warning labels in several countries, has said, 'Our results suggest that graphic warning labels significantly enhance paying attention to warnings'" ("Cigarette Warning"). The same article advances other advantages of warning labels: "According to Thomas Glynn of the American Cancer Society, 'For smokers, [the warning label is] a new and very visible reminder that smoking can harm them, harm people around them, including children. For nonsmokers, it's a reminder that smokers need their help and concern as far as quitting. The labels are not just for smokers, the labels are for anyone interested in public health'" ("Cigarette Warning").

This paragraph effectively relates the writer's source material to his ideas about warning labels on packs of cigarettes.
