Example Input: A new approach to avoiding overhead wires is taken by the "second generation" tram/streetcar system in Bordeaux, France (entry into service of the first line in December 2003; original system discontinued in 1958) with its APS (alimentation par sol – ground current feed). This involves a third rail which is flush with the surface like the tops of the running rails. The circuit is divided into segments with each segment energized in turn by sensors from the car as it passes over it, the remainder of the third rail remaining "dead". Since each energized segment is completely covered by the lengthy articulated cars, and goes dead before being "uncovered" by the passage of the vehicle, there is no danger to pedestrians. This system has also been adopted in some sections of the new tram systems in Reims, France (opened 2011) and Angers, France (also opened 2011). Proposals are in place for a number of other new services including Dubai, UAE; Barcelona, Spain; Florence, Italy; Marseille, France; Gold Coast, Australia; Washington, D.C., U.S.A.; Brasília, Brazil and Tours, France.
Example Output: What year the "second generation" of tram system began to operate in France?

Example Input: The Low German varieties spoken in Germany are often counted among the German dialects. This reflects the modern situation where they are roofed by standard German. This is different from the situation in the Middle Ages when Low German had strong tendencies towards an ausbau language.
Example Output: What type of language was Low German in the Middle Ages?

Example Input: Although Kenya is the biggest and most advanced economy in east and central Africa, and has an affluent urban minority, it has a Human Development Index (HDI) of 0.519, ranked 145 out of 186 in the world. As of 2005, 17.7% of Kenyans lived on less than $1.25 a day. The important agricultural sector is one of the least developed and largely inefficient, employing 75% of the workforce compared to less than 3% in the food secure developed countries. Kenya is usually classified as a frontier market or occasionally an emerging market, but it is not one of the least developed countries.
Example Output:
What is Kenya's HDI?
