Problem: Given the question: Question: "Why is Tucson running part of its share of Cap water into local rivers to seep into their aquifer?" 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." Answer:

The answer is:
In an effort to conserve water

input question: Question: "In what reaction will the formation of organomagnesium halide fail if water is present?" Context: "There are many important organozinc compounds. Organozinc chemistry is the science of organozinc compounds describing their physical properties, synthesis and reactions. Among important applications is the Frankland-Duppa Reaction in which an oxalate ester(ROCOCOOR) reacts with an alkyl halide R'X, zinc and hydrochloric acid to the -hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts -halo-esters and aldehydes to -hydroxy-esters, the SimmonsSmith reaction in which the carbenoid (iodomethyl)zinc iodide reacts with alkene(or alkyne) and converts them to cyclopropane, the Addition reaction of organozinc compounds to carbonyl compounds. The Barbier reaction (1899) is the zinc equivalent of the magnesium Grignard reaction and is better of the two. In presence of just about any water the formation of the organomagnesium halide will fail, whereas the Barbier reaction can even take place in water. On the downside organozincs are much less nucleophilic than Grignards, are expensive and difficult to handle. Commercially available diorganozinc compounds are dimethylzinc, diethylzinc and diphenylzinc. In one study the active organozinc compound is obtained from much cheaper organobromine precursors:" Answer:???
output answer: magnesium Grignard reaction

Question: "What is a characteristic shared among MetLife Stadium, Yankee Stadium, Madison Square Garden, and Citi Field?" Context: "New York City is home to the headquarters of the National Football League, Major League Baseball, the National Basketball Association, the National Hockey League, and Major League Soccer. The New York metropolitan area hosts the most sports teams in these five professional leagues. Participation in professional sports in the city predates all professional leagues, and the city has been continuously hosting professional sports since the birth of the Brooklyn Dodgers in 1882. The city has played host to over forty major professional teams in the five sports and their respective competing leagues, both current and historic. Four of the ten most expensive stadiums ever built worldwide (MetLife Stadium, the new Yankee Stadium, Madison Square Garden, and Citi Field) are located in the New York metropolitan area. Madison Square Garden, its predecessor, as well as the original Yankee Stadium and Ebbets Field, are some of the most famous sporting venues in the world, the latter two having been commemorated on U.S. postage stamps." Answer:
----
Answer: most expensive stadiums ever built worldwide

Q: Question: "What were the conditions of the licenses?" Context: "In the next two years, the company established its first factory in south India in the town of Machilipatnam on the Coromandel Coast of the Bay of Bengal. The high profits reported by the company after landing in India initially prompted King James I to grant subsidiary licences to other trading companies in England. But in 1609 he renewed the charter given to the company for an indefinite period, including a clause that specified that the charter would cease to be in force if the trade turned unprofitable for three consecutive years." Answer:
A: a clause that specified that the charter would cease to be in force if the trade turned unprofitable for three consecutive years

Question: Question: "Which came later, the 16th or 20th century?" Context: "South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences." Answer:
Answer: 20th
