For the Health Topics Materials data model attached, list the following:

a$.$ all the entities

b$.$all the attributes in each entity

c$.$the primary key for each entity

d$.$all the foreign keys

e$.$all the relationship cardinalities between entities $($e$.$g$.,$ a professor can teach one to many classes; an individual class is taught by one and only one professor$)$

f$.$for each relationship between entities, specify the name of the attribute in one entity that will be used to match to an attribute in a related entity, including the specific attribute name in the second entity that is used for the matching. For example, in a school data model: $$The Student$\_$ID attribute in the Registered$\_$Class entity is used to match to the Student$\_$ID attribute in the Enrolled$\_$Student entity.$$
