Problem: Pain:

In 1644, René Descartes theorized that pain was a disturbance that passed down along nerve fibers until the disturbance reached the brain, a development that transformed the perception of pain from a spiritual, mystical experience to a physical, mechanical sensation[citation needed]. Descartes's work, along with Avicenna's, prefigured the 19th-century development of specificity theory. Specificity theory saw pain as "a specific sensation, with its own sensory apparatus independent of touch and other senses". Another theory that came to prominence in the 18th and 19th centuries was intensive theory, which conceived of pain not as a unique sensory modality, but an emotional state produced by stronger than normal stimuli such as intense light, pressure or temperature. By the mid-1890s, specificity was backed mostly by physiologists and physicians, and the intensive theory was mostly backed by psychologists. However, after a series of clinical observations by Henry Head and experiments by Max von Frey, the psychologists migrated to specificity almost en masse, and by century's end, most textbooks on physiology and psychology were presenting pain specificity as fact.

Problem: Near East:

The populations of those lands did not accept Turkish rule. The Turks to them were foreigners with completely different customs, way of life, and language. Intervals when there was no unrest were rare. The Hungarians had thrown off Turkish rule by 1688. Serbia was created by the Serbian Revolution, 1815–1833. The Greek War of Independence, 1821–1832, created modern Greece, which recovered most of the lands of ancient Greece, but could not gain Constantinople. The Ottoman Porte was continuously under attack from some quarter in its empire, primarily the Balkans. Also, on a number of occasions in the early 19th century, American and British warships had to attack the Barbary pirates to stop their piracy and recover thousands of enslaved Europeans and Americans.

What created Serbia?

A: the Serbian Revolution


Problem: Arsenal F.C.:

Terry Neill was recruited by the Arsenal board to replace Bertie Mee on 9 July 1976 and at the age of 34 he became the youngest Arsenal manager to date. With new signings like Malcolm Macdonald and Pat Jennings, and a crop of talent in the side such as Liam Brady and Frank Stapleton, the club enjoyed their best form since the 1971 double, reaching a trio of FA Cup finals (1978, 1979 and 1980), and losing the 1980 European Cup Winners' Cup Final on penalties. The club's only success during this time was a last-minute 3–2 victory over Manchester United in the 1979 FA Cup Final, widely regarded as a classic.

What number of cup finals did Arsenal reach in

A: trio


Problem: House music:

Juan Atkins, an originator of Detroit techno music, claims the term "house" reflected the exclusive association of particular tracks with particular clubs and DJs; those records helped differentiate the clubs and DJs, and thus were considered to be their "house" records. In an effort to maintain such exclusives, the DJs were inspired to create their own "house" records.

Why were DJs inspired to create their own Atkins records?
