OK,

But the posts in the previous Q seemed to have explained this for the most part.

This is the thing with these "Academic" assignments....
They seek to "Challenge" you.  ...And that's a good thing, ... but in making the Q so complex, it often confuses you first.

For example, it is rare to get an entire DB schema with *No* existing relationships between tables.
Are you also to assume that this design is properly normalized for the task at hand?

It is also not clear how much you understand about this design or the task at hand.
In other words, are you saying that you read all the supporting documentation and class notes and still have no "understanding" of the question?

The purpose of this sight is to provide guidance in situations like this.
So you must demonstrate that you did some independent research of your own, and what the results were, ... and not just simply present the assignment verbatim from the text book and state that you do not "understand it".
Sound fair?

The query itself is not that difficult to get once the tables are properly related.
So the question of "Understanding" this is a bit broad.
Can you state the one *specific* thing here you are seeking to understand?
Normalization?, Keys?, Relationships?, SQL Query structure?
...as the focus of any one question here can only be one distinct topic.

Thanks
