Problem: Arsenal F.C.:

Arsenal fans often refer to themselves as "Gooners", the name derived from the team's nickname, "The Gunners". The fanbase is large and generally loyal, and virtually all home matches sell out; in 200708 Arsenal had the second-highest average League attendance for an English club (60,070, which was 99.5% of available capacity), and, as of 2015, the third-highest all-time average attendance. Arsenal have the seventh highest average attendance of European football clubs only behind Borussia Dortmund, FC Barcelona, Manchester United, Real Madrid, Bayern Munich, and Schalke. The club's location, adjoining wealthy areas such as Canonbury and Barnsbury, mixed areas such as Islington, Holloway, Highbury, and the adjacent London Borough of Camden, and largely working-class areas such as Finsbury Park and Stoke Newington, has meant that Arsenal's supporters have come from a variety of social classes.

Problem: The first European to visit the region was Portuguese-born explorer Juan Rodriguez Cabrillo sailing under the flag of Castile. Sailing his flagship San Salvador from Navidad, New Spain, Cabrillo claimed the bay for the Spanish Empire in 1542, and named the site 'San Miguel'. In November 1602, Sebastian Vizcaino was sent to map the California coast. Arriving on his flagship San Diego, Vizcaino surveyed the harbor and what are now Mission Bay and Point Loma and named the area for the Catholic Saint Didacus, a Spaniard more commonly known as San Diego de Alcala. On November 12, 1602, the first Christian religious service of record in Alta California was conducted by Friar Antonio de la Ascension, a member of Vizcaino's expedition, to celebrate the feast day of San Diego.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
There are special rules for certain rare diseases ("orphan diseases") in several major drug regulatory territories. For example, diseases involving fewer than 200,000 patients in the United States, or larger populations in certain circumstances are subject to the Orphan Drug Act. Because medical research and development of drugs to treat such diseases is financially disadvantageous, companies that do so are rewarded with tax reductions, fee waivers, and market exclusivity on that drug for a limited time (seven years), regardless of whether the drug is protected by patents.
What is one financial benefit to researching orphan drugs?
A: tax reductions

The most important early proponent of Whitehead's thought in a theological context was Charles Hartshorne, who spent a semester at Harvard as Whitehead's teaching assistant in 1925, and is widely credited with developing Whitehead's process philosophy into a full-blown process theology. Other notable process theologians include John B. Cobb, Jr., David Ray Griffin, Marjorie Hewitt Suchocki, C. Robert Mesle, Roland Faber, and Catherine Keller.

Question: The 2006 renewal and re-equipment effort has resulted in the acquisition of specific equipment (main battle tanks, artillery, unmanned air vehicles and other systems) to support the mission in Afghanistan. It has also encompassed initiatives to renew certain so-called "core capabilities" (such as the air force's medium range transport aircraft fleet the C-130 Hercules and the army's truck and armoured vehicle fleets). In addition, new systems (such as C-17 Globemaster III strategic transport aircraft and CH-47 Chinook heavy-lift helicopters) have also been acquired for the Armed Forces. Although the viability of the Canada First Defence Strategy continues to suffer setbacks from challenging and evolving fiscal and other factors, it originally aimed to:

Problem: Department store:

Arnold, Constable was the first American department store. It was founded in 1825 by Aaron Arnold (1794?-1876), an emigrant from Great Britain, as a small dry goods store on Pine Street in New York City. In 1857 the store moved into a five-story white marble dry goods palace known as the Marble House. During the Civil War Arnold, Constable was one of the first stores to issue charge bills of credit to its customers each month instead of on a bi-annual basis. Recognized as an emporium for high-quality fashions, the store soon outgrew the Marble House and erected a cast-iron building on Broadway and Nineteenth Street in 1869; this "Palace of Trade" expanded over the years until it was necessary to move into a larger space in 1914. In 1925, Arnold, Constable merged with Stewart & Company and expanded into the suburbs, first with a 1937 store in New Rochelle, New York and later in Hempstead and Manhasset on Long Island, and in New Jersey. Financial problems led to bankruptcy in 1975.
