For this section, there are 5 questions at the end related to the number of nodes and relations in the graph for: Person Node Count; Movie Node Count; User Node Count; Acted in Relationship; and Directed Relationship. The answers seem to depend on the graph pre-Use-Case #7 in the section, which adds in an additional movie, person, and DIRECTED_IN relation. Was this the intent, or should the correct answers account for this addition to the graph for Use-Case #7 (as this use-case also makes a point to specifically show what the new instance data model should look like after running the code)?
