The Water, Sanitation and Hygiene (WSH) program of the Gates Foundation was launched in mid-2005 as a "Learning Initiative," and became a full-fledged program under the Global Development Division in early 2010. The Foundation has since 2005 undertaken a wide range of efforts in the WASH sector involving research, experimentation, reflection, advocacy, and field implementation. In 2009, the Foundation decided to refocus its WASH effort mainly on sustainable sanitation services for the poor, using non-piped sanitation services (i.e. without the use of sewers), and less on water supply. This was because the sanitation sector was generally receiving less attention from other donors and from governments, and because the Foundation believed it had the potential to make a real difference through strategic investments.

The problem: Answer a question about this article:
The toponym Schwyz itself is first attested in 972, as Old High German Suittes, ultimately perhaps related to suedan "to burn", referring to the area of forest that was burned and cleared to build. The name was extended to the area dominated by the canton, and after the Swabian War of 1499 gradually came to be used for the entire Confederation. The Swiss German name of the country, Schwiiz, is homophonous to that of the canton and the settlement, but distinguished by the use of the definite article (d'Schwiiz for the Confederation, but simply Schwyz for the canton and the town).
What was the Swiss German name for Schwyz?

The answer: Schwiiz


The problem: Answer a question about this article:
Since incandescent light bulbs use more energy than alternatives such as CFLs and LED lamps, many governments have introduced measures to ban their use, by setting minimum efficacy standards higher than can be achieved by incandescent lamps. Measures to ban light bulbs have been implemented in the European Union, the United States, Russia, Brazil, Argentina, Canada and Australia, among others. In the Europe the EC has calculated that the ban contributes 5 to 10 billion euros to the economy and saves 40 TWh of electricity every year, translating in CO2 emission reductions of 15 million tonnes.
How are laws written that bring about a ban of incandescent light bulbs?

The answer:
by setting minimum efficacy standards higher than can be achieved by incandescent lamps
