From the Ivy League to the great public universities of the South and Midwest, student demonstrators have called for the renaming of buildings and academic departments, the removal of artworks and even the scrapping of sports team mascots that celebrate controversial aspects of history.

【翻译】从常青藤盟校到南部和中西部的公立大学，学生示威者呼吁给建筑物和学术部门重新命名，要求撤走艺术品甚至取消运动队的吉祥物，这些吉祥物宣示着历史上一些有争议的方面。

【分析】that celebrate controversial aspects of history的先行词，应为mascots；因为mascots还是修饰前面的the scrapping，所以that从句不可能涉及到更远的artworks等。
