 From above:

1) Where is term used?

2) Where is agency used?

3) If you are returning two fields why is there only one in the query?

It might be best to outline the procedure you want to execute. As example:

1) Consume inputs of this type and layout.

2) Process inputs this way.

3) Output this.
