Input: Read this: Northwestern's Evanston campus, where the undergraduate schools, the Graduate School, and the Kellogg School of Management are located, runs north-south from Lincoln Avenue to Clark Street west of Lake Michigan along Sheridan Road. North and South Campuses have noticeably different atmospheres, owing to the predominance of Science and Athletics in the one and Humanities and Arts in the other. North Campus is home to the fraternity quads, the Henry Crown Sports Pavilion and Norris Aquatics Center and other athletic facilities, the Technological Institute, Dearborn Observatory, and other science-related buildings including Patrick G. and Shirley W. Ryan Hall for Nanofabrication and Molecular Self-Assembly, and the Ford Motor Company Engineering Design Center. South Campus is home to the University's humanities buildings, Pick-Staiger Concert Hall and other music buildings, the Mary and Leigh Block Museum of Art, and the sorority quads. In the 1960s, the University created an additional 84 acres (34.0 ha) by means of a lakefill in Lake Michigan. Among some of the buildings located on these broad new acres are University Library, Norris University Center (the student union), and Pick-Staiger Concert Hall.

Input: Read this: The controversy surrounding affirmative action's effectiveness is based on the idea of class inequality. Opponents of racial affirmative action argue that the program actually benefits middle- and upper-class African Americans and Hispanic Americans at the expense of lower-class European Americans and Asian Americans. This argument supports the idea of class-based affirmative action. America's poor is disproportionately made up of people of color, so class-based affirmative action would disproportionately help people of color. This would eliminate the need for race-based affirmative action as well as reducing any disproportionate benefits for middle- and upper-class people of color.
Question: Who primarily makes up America's rich group?

Output: unanswerable
