1. According to Bryson, what is “boundary work” and who does it?
| it is the drawing of congressional districts; legislators do it |

| 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 |
