Problem: United States Air Force:

The U.S. War Department created the first antecedent of the U.S. Air Force in 1907, which through a succession of changes of organization, titles, and missions advanced toward eventual separation 40 years later. In World War II, almost 68,000 U.S airmen died helping to win the war; only the infantry suffered more enlisted casualties. In practice, the U.S. Army Air Forces (USAAF) was virtually independent of the Army during World War II, but officials wanted formal independence. The National Security Act of 1947 was signed on on 26 July 1947 by President Harry S Truman, which established the Department of the Air Force, but it was not not until 18 September 1947, when the first secretary of the Air Force, W. Stuart Symington was sworn into office that the Air Force was officially formed.

A: 68,000

An FBI special agent is issued a Glock Model 22 pistol or a Glock 23 in .40 S&W caliber. If they fail their first qualification, they are issued either a Glock 17 or Glock 19, to aid in their next qualification. In May 1997, the FBI officially adopted the Glock .40 S&W pistol for general agent use and first issued it to New Agent Class 98-1 in October 1997. At present, the Model 23 "FG&R" (finger groove and rail) is the issue sidearm. New agents are issued firearms, on which they must qualify, on successful completion of their training at the FBI Academy. The Glock 26 in 9×19mm Parabellum, and Glock Models 23 and 27 in .40 S&W caliber are authorized as secondary weapons. Special agents are authorized to purchase and qualify with the Glock Model 21 in .45 ACP.

Problem: Avicenna:

Early Islamic philosophy and Islamic metaphysics, imbued as it is with Islamic theology, distinguishes more clearly than Aristotelianism between essence and existence. Whereas existence is the domain of the contingent and the accidental, essence endures within a being beyond the accidental. The philosophy of Ibn Sīnā, particularly that part relating to metaphysics, owes much to al-Farabi. The search for a definitive Islamic philosophy separate from Occasionalism can be seen in what is left of his work.

What is early Islamic metaphysics imbued with?
---
A: Islamic theology


Problem: Valencia:

The 15th century was a time of Islamic economic expansion, known as the Valencian Golden Age, in which culture and the arts flourished. Concurrent population growth made Valencia the most populous city in the Crown of Aragon. Local industry, led by textile production, reached a great development, and a financial institution, the Canvi de Taula, was created to support municipal banking operations; Valencian bankers lent funds to Queen Isabella I of Castile for Columbus's voyage in 1492. At the end of the century the Silk Exchange (Llotja de la Seda) building was erected as the city became a commercial emporium that attracted merchants from all over Europe.

Queen Isabella I of Castile
