Consider developing a database of furniture  in a house, 
where we need to keep a record of the item, its’ location 
and the amount.   For example to describe the six chairs 
in the dinning room we could use:

	furniture(chair,dining_room,6).

Extract facts from the paragraph below and build a similar 
database (Feel free to change).

	"There are three sofas in the house, 
	two in the sitting-room and another 
	in the lounge, where four Victorian 
	chairs pair up with a round table.  
	Two other tables are found in the 
	kitchen and sitting-room.  In the 
	kitchen there is also a sink, two 
	cooking devices and two chairs which 
	were originally in the bedroom.  In 
	this room there is a huge wardrobe 
	and a pair of bunk-beds".


Write queries to:
a) Find how many chairs are in each room
b) Where are all the tables
c) Which rooms have four items the same
