Problem: John remained Lord of Ireland throughout his reign. He drew on the country for resources to fight his war with Philip on the continent. Conflict continued in Ireland between the Anglo-Norman settlers and the indigenous Irish chieftains, with John manipulating both groups to expand his wealth and power in the country. During Richard's rule, John had successfully increased the size of his lands in Ireland, and he continued this policy as king. In 1210 the king crossed into Ireland with a large army to crush a rebellion by the Anglo-Norman lords; he reasserted his control of the country and used a new charter to order compliance with English laws and customs in Ireland. John stopped short of trying to actively enforce this charter on the native Irish kingdoms, but historian David Carpenter suspects that he might have done so, had the baronial conflict in England not intervened. Simmering tensions remained with the native Irish leaders even after John left for England.
During Richard's rule, what did John successfully do?
---
Answer: increased the size of his lands in Ireland


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.
How are scratches on the labeled side of a disc fixed?
A: unanswerable


Context and question: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
When did France relinquish control of Morocco?
Answer: unanswerable


Question: The competition formed as the FA Premier League on 20 February 1992 following the decision of clubs in the Football League First Division to break away from the Football League, which was originally founded in 1888, and take advantage of a lucrative television rights deal. The deal was worth £1 billion a year domestically as of 2013–14, with BSkyB and BT Group securing the domestic rights to broadcast 116 and 38 games respectively. The league generates €2.2 billion per year in domestic and international television rights. In 2014/15, teams were apportioned revenues of £1.6 billion.
Is there an answer to this question: How much revenue were teams given during 2013/14?

Answer: unanswerable


Problem: Middle Ages:

The construction of cathedrals and castles advanced building technology, leading to the development of large stone buildings. Ancillary structures included new town halls, houses, bridges, and tithe barns. Shipbuilding improved with the use of the rib and plank method rather than the old Roman system of mortise and tenon. Other improvements to ships included the use of lateen sails and the stern-post rudder, both of which increased the speed at which ships could be sailed.

What type of sails were first used during this era?
---
A:
lateen
