Ex 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.

Ex Output:
What year the "second generation" of tram system began to operate in France?


Ex Input:
Hokkien /hɒˈkiɛn/ (traditional Chinese: 福建話; simplified Chinese: 福建话; pinyin: Fújiànhuà; Pe̍h-ōe-jī: Hok-kiàn oē) or Quanzhang (Quanzhou–Zhangzhou / Chinchew–Changchew; BP: Zuánziū–Ziāngziū) is a group of mutually intelligible Min Nan Chinese dialects spoken throughout Southeast Asia, Taiwan, and by many other overseas Chinese. Hokkien originated from a dialect in southern Fujian. It is closely related to the Teochew, though mutual comprehension is difficult, and is somewhat more distantly related to Hainanese. Besides Hokkien, there are also other Min and Hakka dialects in Fujian province, most of which are not mutually intelligible with Hokkien.

Ex Output:
Where did Hokkien originate?


Ex Input:
The state seemed at relative calm compared to the rest of the country due to its close ties to the United States until 1841. In 1843 the possibility of war was anticipated by the state government and it began to reinforce the defense lines along the political boundary with Texas. Supplies of weapons were sent to fully equip the military and took steps to improve efficiency at the presidios. Later, the Regimen for the Defenders of the Border were organized by the state which were made up of: light cavalry, four squads of two brigades, and a small force of 14 men and 42 officials at the price of 160,603 pesos per year. During the beginning of the 1840s, private citizens took it upon themselves to stop the commercial caravans of supplies from the United States, but being so far away from the large suppliers in central Mexico the caravan was allowed to continue in March 1844. Continuing to anticipate a war, the state legislature on July 11, 1846 by decree enlisted 6,000 men to serve along the border; during that time Ángel Trías quickly rose to power by portraying zealous anti-American rhetoric. Trías took the opportunity to dedicate important state resources to gain economic concessions from the people and loans from many municipalities in preparation to defend the state; he used all the money he received to equip and organize a large volunteer militia. Ángel Trías took measures for state self-dependence in regards to state militia due to the diminishing financial support from the federal government.

Ex Output:

Until what year did the state remain calm?
