Input: Read this: Switzerland has a dense network of cities, where large, medium and small cities are complementary. The plateau is very densely populated with about 450 people per km2 and the landscape continually shows signs of human presence. The weight of the largest metropolitan areas, which are Zürich, Geneva–Lausanne, Basel and Bern tend to increase. In international comparison the importance of these urban areas is stronger than their number of inhabitants suggests. In addition the two main centers of Zürich and Geneva are recognized for their particularly great quality of life.
Question: What is the population density of the plateau?

Output: 450 people per km2


Input: Read this: The double indirect method can be used when it is important to see the work during the creation process as it will appear when completed. The tesserae are placed face-up on a medium (often adhesive-backed paper, sticky plastic or soft lime or putty) as it will appear when installed. When the mosaic is complete, a similar medium is placed atop it. The piece is then turned over, the original underlying material is carefully removed, and the piece is installed as in the indirect method described above. In comparison to the indirect method, this is a complex system to use and requires great skill on the part of the operator, to avoid damaging the work. Its greatest advantage lies in the possibility of the operator directly controlling the final result of the work, which is important e.g. when the human figure is involved. This method was created in 1989 by Maurizio Placuzzi and registered for industrial use (patent n. 0000222556) under the name of his company, Sicis International Srl, now Sicis The Art Mosaic Factory Srl.
Question: When is the double indirect method of mosaic useful?

Output: when it is important to see the work
