24. Glasgow is mentioned in Paragraph 3 to present_______

解析：根据题干中的“Glasgow”以及“Paragraph 3”可定位至第三段最后一句“It is hard to get right, and requires a remarkable degree of vision, as well as cooperation between city authorities, the private sector, community. groups and cultural organizations. But it can be done: ...”。可知作者认为，虽然要实现真正的长期发展很难，需要高度的远见卓识，以及城市管理者、私营部门、社区、团体和文化组织之间的合作，但是这是有可能实现的，例如Glasgow就做到了实至名归。可知Glasgow此处是作为正面例证来证明城市可以正确地利用头衔，发展自我，故答案为B。
