Answer:
'During a relatively brief period of time, the fast food industry has helped to transform not only the American diet, but also our landscape, economy, workforce, and popular culture'.
Explanation:
The book, 'Fast Food Nation', written by Eric Schlosser in 2001 narrates the infiltration of fast food in America. The evidence to support the statement that fast food has infiltrated the American society over the last three decades can be found in the quote above from the book. Three decades before 2001 began in 1970 which was just a short period of time. Also, the fact that fast food has infiltrated all the nooks and crannies of the American society is found in the fact that restaurants, airports, airplanes, trains, ships, gas stations, Wal-Marts, and even hospital cafeterias now sell fast food. These represent the diet, landscape, economy, workforce, and popular culture of the American society which were affected within a brief period of time.
More evidence is found in the spending nature of Americans which have seen a huge investment in fast food that in other important aspects of the American society such as education, software, films and literature.
