I see someone has already answered but to help out a bit more ill explain why the answer is "true". When you go on a plane you got bags right? sometimes boxes or dressers to! so those would be considered "freight". Not the bags but things like boxes or dressers, and sometimes planes are even asked to take a small load of freight with them to their destination since it needed to go there anyway and they have room.

We have two types of dependency. The partial dependency and the transitive dependency.

The answer here is partial dependency. It occurs when the attribute only depends on some parts of the element. In such attribute, the primary key is the determinant.

It can be shown as;

XY→WZ , X→W and XY is the primary key or the only candidate key
