The challenge here is to learn how not only to assign content to one of the agreed-upon topic types (concept, task, or reference), but also to mind the context of the overall learning objective.
答：信息类型描述主题的类别，例如概念、任务或引用。
A: An information type describes a category of topics, such as concepts, tasks, or reference.
该体系结构的基础是主题结构，由此衍生出了概念、任务和引用结构。
