Thus, while the rest of Europe saw revolutionary uprisings, the Swiss drew up a constitution which provided for a federal layout, much of it inspired by the American example. This constitution provided for a central authority while leaving the cantons the right to self-government on local issues. Giving credit to those who favoured the power of the cantons (the Sonderbund Kantone), the national assembly was divided between an upper house (the Council of States, two representatives per canton) and a lower house (the National Council, with representatives elected from across the country). Referenda were made mandatory for any amendment of this constitution.
What was the name of the upper house, which included 2 representatives from each canton?

The problem: Answer a question about this article:
The Earth receives 174,000 terawatts (TW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most people around the world live in areas with insolation levels of 150 to 300 watts per square meter or 3.5 to 7.0 kWh/m2 per day.
What are the insolation levels of most populated areas?
****
The answer:
150 to 300 watts per square meter or 3.5 to 7.0 kWh/m2 per day
