1. According to Bryson, what is “boundary work” and who does it?

it is the drawing of congressional districts; legislators do it
it is the establishment of qualifications for jobs; employers do it
it is the establishment of boundaries against those we dislike; we all do it
it is the establishment of career ladders within firms; employers do it

2. For Americans in general, the most liked genres of music are ____ and the most disliked genres are ____.

jazz and classical; oldies and easy listening

jazz and classical; gospel and country
oldies and country; heavy metal and rap

3. According to Bryson, which of the following best describes the musical tastes of highly educated, upper middle class Americans?

they dislike all genres of popular music and listen only to classical music
they dislike far fewer musical genres than people from lower classes
they like all musical genres, but especially like country and gospel
they like all musical genres, but especially like heavy metal and rap

they have below average levels of education
they are older

they listen to the most popular types of music

5. Based on Bryson’s findings and what you have learned about social stratification, how might boundary work affect inequality?

boundary work reduces inequality, because everyone does boundary work
boundary work reproduces inequality, because "gatekeepers" tend to exclude those whose tastes or dispositions differ from their own
boundary work reduces inequality, since all who achieve the same level of education gain admission into the elite
boundary work reduces inequality, because the yardsticks that members of the elite apply to the rest of us vary widely from member of the elite to another
