Problem: Lancashire:

The county was established in 1182, later than many other counties. During Roman times the area was part of the Brigantes tribal area in the military zone of Roman Britain. The towns of Manchester, Lancaster, Ribchester, Burrow, Elslack and Castleshaw grew around Roman forts. In the centuries after the Roman withdrawal in 410AD the northern parts of the county probably formed part of the Brythonic kingdom of Rheged, a successor entity to the Brigantes tribe. During the mid-8th century, the area was incorporated into the Anglo-Saxon Kingdom of Northumbria, which became a part of England in the 10th century.

In what century were Roman forts first established?

Problem: By 500 BCE, Greeks arrived in the desert. Greek traders spread along the eastern coast of the desert, establishing trading colonies along the Red Sea. The Carthaginians explored the Atlantic coast of the desert, but the turbulence of the waters and the lack of markets caused a lack of presence further south than modern Morocco. Centralized states thus surrounded the desert on the north and east; it remained outside the control of these states. Raids from the nomadic Berber people of the desert were a constant concern of those living on the edge of the desert.
Who was responsible for the raids on the Berber people?

Although Classical music in the 2000s has lost most of its tradition for musical improvisation, from the Baroque era to the Romantic era, there are examples of performers who could improvise in the style of their era. In the Baroque era, organ performers would improvise preludes, keyboard performers playing harpsichord would improvise chords from the figured bass symbols beneath the bass notes of the basso continuo part and both vocal and instrumental performers would improvise musical ornaments. J.S. Bach was particularly noted for his complex improvisations. During the Classical era, the composer-performer Mozart was noted for his ability to improvise melodies in different styles. During the Classical era, some virtuoso soloists would improvise the cadenza sections of a concerto. During the Romantic era, Beethoven would improvise at the piano. For more information, see Improvisation.
Who was noted for his complex improvisations?
A: J.S. Bach

Context and question: The United Nations formulates multiple regional divisions as is convenient for its various operations. But few of them include a Near East, and that poorly defined. UNICEF recognizes the "Middle East and North Africa" region, where the Middle East is bounded by the Red Sea on the west and includes Iran on the east. UNESCO recognizes neither a Near East nor a Middle East, dividing the countries instead among three regions: Arab States, Asia and the Pacific, and Africa. Its division "does not forcibly reflect geography" but "refers to the execution of regional activities." The United Nations Statistics Division defines Western Asia to contain the countries included elsewhere in the Middle East. The Food and Agriculture Organization (FAO) describes its entire theatre of operations as the Near East, but then assigns many of its members to other regions as well; for example, Cyprus, Malta and Turkey are in both the European and the Near Eastern regions. Its total area extends further into Central Asia than that of most agencies.
The United Nations Statistics Division defines Western Asia to contain what?
Answer: the countries included elsewhere in the Middle East

Question: After the Indian Rebellion of 1857, the British East India Company, which had ruled much of India, was dissolved, and Britain's possessions and protectorates on the Indian subcontinent were formally incorporated into the British Empire. The Queen had a relatively balanced view of the conflict, and condemned atrocities on both sides. She wrote of "her feelings of horror and regret at the result of this bloody civil war", and insisted, urged on by Albert, that an official proclamation announcing the transfer of power from the company to the state "should breathe feelings of generosity, benevolence and religious toleration". At her behest, a reference threatening the "undermining of native religions and customs" was replaced by a passage guaranteeing religious freedom.
