Problem: Sino-Tibetan relations during the Ming dynasty:

The Mongol prince Godan, a grandson of Genghis Khan, raided as far as Lhasa. During his attack in 1240, Prince Godan summoned Sakya Pandita (11821251), leader of the Sakya school of Tibetan Buddhism, to his court in what is now Gansu in Western China. With Sakya Pandita's submission to Godan in 1247, Tibet was officially incorporated into the Mongol Empire during the regency of Toregene Khatun (12411246). Michael C. van Walt van Praag writes that Godan granted Sakya Pandita temporal authority over a still politically fragmented Tibet, stating that "this investiture had little real impact" but it was significant in that it established the unique "Priest-Patron" relationship between the Mongols and the Sakya lamas.

In what years was Toregene Khatun the regent of the Mongol Empire?

A: 12411246

Problem: However, by the turn of the 1990s the downward trend was starting to reverse; England had been successful in the 1990 FIFA World Cup, reaching the semi-finals. UEFA, European football's governing body, lifted the five-year ban on English clubs playing in European competitions in 1990 (resulting in Manchester United lifting the UEFA Cup Winners' Cup in 1991) and the Taylor Report on stadium safety standards, which proposed expensive upgrades to create all-seater stadiums in the aftermath of the Hillsborough disaster, was published in January of that year.
Did the UEFA remove the 5 year ban on English clubs playing in European competitions in 1990?

Answer: UEFA, European football's governing body, lifted the five-year ban on English clubs playing in European competitions in 1990

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The first political factions, cohering around a basic, if fluid, set of principles emerged from the Exclusion Crisis and Glorious Revolution in late-17th-century England. The Whigs supported Protestant constitutional monarchy against absolute rule and the Tories, originating in the Royalist (or "Cavalier") faction of the English Civil War, were conservative royalist supporters of a strong monarchy as a counterbalance to the republican tendencies of Whigs, who were the dominant political faction for most of the first half of the 18th century; they supported the Hanoverian succession of 1715 against the Jacobite supporters of the deposed Roman Catholic Stuart dynasty and were able to purge Tory politicians from important government positions after the failed Jacobite rising of 1715. The leader of the Whigs was Robert Walpole, who maintained control of the government in the period 17211742; his protege was Henry Pelham (17431754).
How long did the English Civil War last?
A: unanswerable

Context and question: During his time as an American envoy to France, Benjamin Franklin, publisher of the old English proverb, "Early to bed, and early to rise, makes a man healthy, wealthy and wise", anonymously published a letter suggesting that Parisians economize on candles by rising earlier to use morning sunlight. This 1784 satire proposed taxing shutters, rationing candles, and waking the public by ringing church bells and firing cannons at sunrise. Despite common misconception, Franklin did not actually propose DST; 18th-century Europe did not even keep precise schedules. However, this soon changed as rail and communication networks came to require a standardization of time unknown in Franklin's day.
What kind of transportation network helped encourage keeping more exact schedules?
Answer: rail

Question: In the religious sphere, this was a period of profound change. The spiritual revolution that took place, saw a waning of the old Greek religion, whose decline beginning in the 3rd century BC continued with the introduction of new religious movements from the East. The cults of deities like Isis and Mithra were introduced into the Greek world. Greek-speaking communities of the Hellenized East were instrumental in the spread of early Christianity in the 2nd and 3rd centuries, and Christianity's early leaders and writers (notably St Paul) were generally Greek-speaking, though none were from Greece. However, Greece itself had a tendency to cling to paganism and was not one of the influential centers of early Christianity: in fact, some ancient Greek religious practices remained in vogue until the end of the 4th century, with some areas such as the southeastern Peloponnese remaining pagan until well into the 10th century AD.
Is there an answer to this question: What encouraged the change of faith ?

Answer: with the introduction of new religious movements from the East.

The British Architectural Library, sometimes referred to as the RIBA Library, was established in 1834 upon the founding of the institute with donations from members. Now, with over four million items, it is one of the three largest architectural libraries in the world and the largest in Europe. Some items from the collections are on permanent display at the Victoria and Albert Museum (V&A) in the V&A + RIBA Architecture Gallery and included in temporary exhibitions at the RIBA and across Europe and North America. Its collections include:
