"Each table must depend on the entire foreign key."
Reason: 1NF requires atomic (single) values and no repeating groups. 2NF (requires 1NF first) requires that non-key attributes depend on the entire primary key (i.e., no partial dependencies for composite keys). It says nothing about a table needing to depend on a foreign key.
