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 miles of sewers are in the city?
Answer: 3,657 miles

Problem: After a lengthy period of formal racial segregation in the former Confederacy following the Reconstruction Era, and bans on interracial marriage in various parts of the country, more people are openly forming interracial unions. In addition, social conditions have changed and many multiracial people do not believe it is socially advantageous to try to "pass" as white. Diverse immigration has brought more mixed-race people into the United States, such as the large population of Hispanics identifying as mestizos. Since the 1980s, the United States has had a growing multiracial identity movement (cf. Loving Day). Because more Americans have insisted on being allowed to acknowledge their mixed racial origins, the 2000 census for the first time allowed residents to check more than one ethno-racial identity and thereby identify as multiracial. In 2008 Barack Obama was elected as the first multiracial President of the United States; he acknowledges both sides of his family and identifies as African American.
What has caused more people of mixed races to the US?
The answer is the following: Diverse immigration

One of the paper's best known front pages, published on 4 May 1982, commemorated the torpedoing of the Argentine ship the General Belgrano by running the story under the headline "GOTCHA". At MacKenzie's insistence, and against the wishes of Murdoch (the mogul was present because almost all the journalists were on strike), the headline was changed for later editions after the extent of Argentinian casualties became known. John Shirley, a reporter for The Sunday Times, witnessed copies of this edition of The Sun being thrown overboard by sailors and marines on HMS Fearless.
What was the Sun's headline on 4 May 1982?
"GOTCHA"

Input: Planck constant
First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.

Who discovered an association between the value E and quantum energy?
Output: Einstein

Input: Article: 90th Street is split into two segments. The first segment, West 90th Street begins at Riverside Drive and ends at Central Park West or West Drive, when it is open, in Central Park on the Upper West Side. The second segment of East 90th Street begins at East Drive, at Engineers Gate of Central Park. When East Drive is closed, East 90th Street begins at Fifth Avenue on the Upper East Side and curves to the right at the FDR Drive becoming East End Avenue. Our Lady of Good Counsel Church, is located on East 90th Street between Third Avenue and Second Avenue, across the street from Ruppert Towers (1601 and 1619 Third Avenue) and Ruppert Park. Asphalt Green, which is located on East 90th Street between York Avenue and East End Avenue.

Now answer this question: Which street begins at East Drive, at Engineers Gate of Central Park?

Output: East 90th Street

Problem: Translation of material into Arabic expanded after the creation of Arabic script in the 5th century, and gained great importance with the rise of Islam and Islamic empires. Arab translation initially focused primarily on politics, rendering Persian, Greek, even Chinese and Indic diplomatic materials into Arabic. It later focused on translating classical Greek and Persian works, as well as some Chinese and Indian texts, into Arabic for scholarly study at major Islamic learning centers, such as the Al-Karaouine (Fes, Morocco), Al-Azhar (Cairo, Egypt), and the Al-Nizamiyya of Baghdad. In terms of theory, Arabic translation drew heavily on earlier Near Eastern traditions as well as more contemporary Greek and Persian traditions.
What type of translation drew heavily on earlier Near Eastern traditions?
The answer is the following:
Arabic
