Problem: Historically, Philadelphia sourced its water by the Fairmount Water Works, the nation's first major urban water supply system. In 1909, Water Works was decommissioned as the city transitioned to modern sand filtration methods. Today, the Philadelphia Water Department (PWD) provides drinking water, wastewater collection, and stormwater services for Philadelphia, as well as surrounding counties. PWD draws about 57 percent of its drinking water from the Delaware River and the balance from the Schuylkill River. The public wastewater system consists of three water pollution control plants, 21 pumping stations, and about 3,657 miles of sewers. A 2007 investigation by the Environmental Protection Agency found elevated levels of Iodine-131 in the city's potable water.[citation needed] In 2012, the EPA's readings discovered that the city had the highest readings of I-131 in the nation. The city campaigned against an Associated Press report that the high levels of I-131 were the results of local gas drilling in the Upper Delaware River.[citation needed]
How many pumping stations are there in the sewer system?
The answer is the following: 21

In many parts of the world football evokes great passions and plays an important role in the life of individual fans, local communities, and even nations. R. Kapuscinski says that Europeans who are polite, modest, or humble fall easily into rage when playing or watching football games. The Cote d'Ivoire national football team helped secure a truce to the nation's civil war in 2006 and it helped further reduce tensions between government and rebel forces in 2007 by playing a match in the rebel capital of Bouake, an occasion that brought both armies together peacefully for the first time. By contrast, football is widely considered to have been the final proximate cause for the Football War in June 1969 between El Salvador and Honduras. The sport also exacerbated tensions at the beginning of the Yugoslav Wars of the 1990s, when a match between Dinamo Zagreb and Red Star Belgrade degenerated into rioting in May 1990.
What city did a peaceful match between two armies take place in 2007?
Bouake

Many of the coinages that have been considered (often by Aavik himself) as words concocted ex nihilo could well have been influenced by foreign lexical items, for example words from Russian, German, French, Finnish, English and Swedish. Aavik had a broad classical education and knew Ancient Greek, Latin and French. Consider roim 'crime' versus English crime or taunima 'to condemn, disapprove' versus Finnish tuomita 'to condemn, to judge' (these Aavikisms appear in Aavik's 1921 dictionary). These words might be better regarded as a peculiar manifestation of morpho-phonemic adaptation of a foreign lexical item.

When was Aavik's dictionary published?
Output: 1921

Input: Article: Beginning and ending dates are roughly the reverse in the southern hemisphere. For example, mainland Chile observed DST from the second Saturday in October to the second Saturday in March, with transitions at 24:00 local time. The time difference between the United Kingdom and mainland Chile could therefore be five hours during the Northern summer, three hours during the Southern summer and four hours a few weeks per year because of mismatch of changing dates.

Now answer this question: At what local time does Chile change their clocks for DST?

Output: 24:00

Article: Raleigh is home to North Carolina State University and is part of the Research Triangle area, together with Durham (home of Duke University) and Chapel Hill (home of the University of North Carolina at Chapel Hill). The "Triangle" nickname originated after the 1959 creation of the Research Triangle Park, located in Durham & Wake Counties partway between the three cities and their universities. The Research Triangle region encompasses the U.S. Census Bureau's Raleigh-Durham-Chapel Hill Combined Statistical Area (CSA), which had an estimated population of 2,037,430 in 2013. The Raleigh Metropolitan Statistical Area (MSA) had an estimated population of 1,214,516 in 2013.

Question: When was the Triangle created?
Ans: 1959

Input: Utrecht
About 69% of the population is of Dutch ancestry. Approximately 10% of the population consists of immigrants from Western countries, while 21% of the population is of non-Western origin (9% Moroccan, 5% Turkish, 3% Surinamese and Dutch Caribbean and 5% of other countries). Some of the city's boroughs have a relatively high percentage of originally non-Dutch inhabitants i.e. Kanaleneiland 83% and Overvecht 57%. Like Rotterdam, Amsterdam, The Hague and other large Dutch cities, Utrecht faces some socio-economic problems. About 38% percent of its population either earns a minimum income or is dependent on social welfare (17% of all households). Boroughs such as Kanaleneiland, Overvecht and Hoograven consist primarily of high-rise housing developments, and are known for relatively high poverty and crime rate.
