Extract the answer to the question from the following context. Question: What is one kind of water does Tucson use to water their crops? Context: In an effort to conserve water, Tucson is recharging groundwater supplies by running part of its share of CAP water into various open portions of local rivers to seep into their aquifer. Additional study is scheduled to determine the amount of water that is lost through evaporation from the open areas, especially during the summer. The City of Tucson already provides reclaimed water to its inhabitants, but it is only used for "applications such as irrigation, dust control, and industrial uses." These resources have been in place for more than 27 years, and deliver to over 900 locations.

Extract the answer to the question from the following context. Question: Candidate's names are included in which type of advertisements? Context: To distinguish official campaigning from independent campaigning, political advertisements on television were required to include a verbal disclaimer identifying the organization responsible for the advertisement. Advertisements produced by political campaigns usually included the statement, "I'm [candidate's name], and I approve this message." Advertisements produced by independent organizations usually included the statement, "[Organization name] is responsible for the content of this advertisement", and from September 3 (60 days before the general election), such organizations' ads were prohibited from mentioning any candidate by name. Previously, television advertisements only required a written "paid for by" disclaimer on the screen.

Extract the answer to the question from the following context. Question: Which group suffered the greatest number of loss of human life: civilians, firefighters, or law enforcement? Context: The city and surrounding area suffered the bulk of the economic damage and largest loss of human life in the aftermath of the September 11, 2001 attacks when 10 of the 19 terrorists associated with Al-Qaeda piloted American Airlines Flight 11 into the North Tower of the World Trade Center and United Airlines Flight 175 into the South Tower of the World Trade Center, and later destroyed them, killing 2,192 civilians, 343 firefighters, and 71 law enforcement officers who were in the towers and in the surrounding area. The rebuilding of the area, has created a new One World Trade Center, and a 9/11 memorial and museum along with other new buildings and infrastructure. The World Trade Center PATH station, which opened on July 19, 1909 as the Hudson Terminal, was also destroyed in the attack. A temporary station was built and opened on November 23, 2003. A permanent station, the World Trade Center Transportation Hub, is currently under construction. The new One World Trade Center is the tallest skyscraper in the Western Hemisphere and the fourth-tallest building in the world by pinnacle height, with its spire reaching a symbolic 1,776 feet (541.3 m) in reference to the year of American independence.
