Rooms has the following columns:
* Title
* Capacity
* Equipment
Offices has the following columns:
* Title
* Rooms (a lookup to the Title column in the Rooms list)
* Rooms: Capacity
* Rooms: Equipment
You need to perform a Representational State Transfer (REST) query that returns a list of all the offices that have rooms with a capacity of 10. The query results must include the room titles and the equipment in each room.
