Would it be wise to map Figure 10.3 using mapping rule 173 Why or why not?

Mapping rule 17:

Mapping generalizations and specializations with disjoint relationships, total or partial participation constraints, and predicate defined with single type attributes. Create a single relation to include the attributes of the generalization (superclass) as well as the attributes of the specializations (subclasses) in one relation. The primary key of the relation will be the primary key of the generalization (superclass).
