Final answer:
The WBS dictionary is to the WBS as the activity attributes are to the activity list, serving as a detailed narrative and description of the work outlined in the WBS.
Step-by-step explanation:
The activity attributes are detailed parts and components of an activity within a project, much like the specifics outlined for each activity in the activity list.
Similarly, the Work Breakdown Structure (WBS) dictionary provides detailed descriptions, often including the work packages, deliverables, and other detailed information that supports the WBS.
Therefore, the WBS dictionary is to the WBS as the activity attributes are to the activity list. The WBS dictionary complements the WBS by providing a detailed narrative of the work described in the WBS elements.
