Miss , may I help you ?   Yes , I just wondered why the price between the ninth and tenth floor is so different .   It's because of the view .   Oh ! I see . Can you show me the location of Block I ?   Sure . Please take a look at the model of the building . Nice Garden has a total of two blocks which are labeled Block I and Block II . Block I has a total of thirty-eighth floors . The thirty-seventh and thirty-eighth are penthouses . There are four units in one floor . The sizes of the units are one thousand square feet and one thousand and five hundred square feet . The size with one thousand square feet has three bedrooms and the biggest size has four bedrooms .   How many elevators are there ?   There are three elevators between one hundred and forty-eight units .   How about the car-park space ?
