Problem: Virgil:

The works of Virgil almost from the moment of their publication revolutionized Latin poetry. The Eclogues, Georgics, and above all the Aeneid became standard texts in school curricula with which all educated Romans were familiar. Poets following Virgil often refer intertextually to his works to generate meaning in their own poetry. The Augustan poet Ovid parodies the opening lines of the Aeneid in Amores 1.1.1–2, and his summary of the Aeneas story in Book 14 of the Metamorphoses, the so-called "mini-Aeneid", has been viewed as a particularly important example of post-Virgilian response to the epic genre. Lucan's epic, the Bellum Civile has been considered an anti-Virgilian epic, disposing with the divine mechanism, treating historical events, and diverging drastically from Virgilian epic practice. The Flavian poet Statius in his 12-book epic Thebaid engages closely with the poetry of Virgil; in his epilogue he advises his poem not to "rival the divine Aeneid, but follow afar and ever venerate its footsteps." In Silius Italicus, Virgil finds one of his most ardent admirers. With almost every line of his epic Punica Silius references Virgil. Indeed, Silius is known to have bought Virgil's tomb and worshipped the poet. Partially as a result of his so-called "Messianic" Fourth Eclogue—widely interpreted later to have predicted the birth of Jesus Christ—Virgil was in later antiquity imputed to have the magical abilities of a seer; the Sortes Vergilianae, the process of using Virgil's poetry as a tool of divination, is found in the time of Hadrian, and continued into the Middle Ages. In a similar vein Macrobius in the Saturnalia credits the work of Virgil as the embodiment of human knowledge and experience, mirroring the Greek conception of Homer. Virgil also found commentators in antiquity. Servius, a commentator of the 4th century AD, based his work on the commentary of Donatus. Servius' commentary provides us with a great deal of information about Virgil's life, sources, and references; however, many modern scholars find the variable quality of his work and the often simplistic interpretations frustrating.

Problem: In October 1919, Albert went up to Trinity College, Cambridge, where he studied history, economics and civics for a year. On 4 June 1920, he was created Duke of York, Earl of Inverness and Baron Killarney. He began to take on more royal duties. He represented his father, and toured coal mines, factories, and railyards. Through such visits he acquired the nickname of the "Industrial Prince". His stammer, and his embarrassment over it, together with his tendency to shyness, caused him to appear much less impressive than his older brother, Edward. However, he was physically active and enjoyed playing tennis. He played at Wimbledon in the Men's Doubles with Louis Greig in 1926, losing in the first round. He developed an interest in working conditions, and was President of the Industrial Welfare Society. His series of annual summer camps for boys between 1921 and 1939 brought together boys from different social backgrounds.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The first reports of the abbey are based on a late tradition claiming that a young fisherman called Aldrich on the River Thames saw a vision of Saint Peter near the site. This seems to be quoted to justify the gifts of salmon from Thames fishermen that the abbey received in later years. In the present era, the Fishmonger's Company still gives a salmon every year. The proven origins are that in the 960s or early 970s, Saint Dunstan, assisted by King Edgar, installed a community of Benedictine monks here.
What was the name of the fisherman in lore that saw a vision of Saint Paul near the Abbey?
A: unanswerable


Context and question: Jehovah's Witnesses are organized hierarchically, in what the leadership calls a "theocratic organization", reflecting their belief that it is God's "visible organization" on earth. The organization is led by the Governing Body—an all-male group that varies in size, but since early 2014 has comprised seven members,[note 1] all of whom profess to be of the "anointed" class with a hope of heavenly life—based in the Watch Tower Society's Brooklyn headquarters. There is no election for membership; new members are selected by the existing body. Until late 2012, the Governing Body described itself as the representative and "spokesman" for God's "faithful and discreet slave class" (approximately 10,000 self-professed "anointed" Jehovah's Witnesses). At the 2012 Annual Meeting of the Watch Tower Society, the "faithful and discreet slave" was defined as referring to the Governing Body only. The Governing Body directs several committees that are responsible for administrative functions, including publishing, assembly programs and evangelizing activities. It appoints all branch committee members and traveling overseers, after they have been recommended by local branches, with traveling overseers supervising circuits of congregations within their jurisdictions. Traveling overseers appoint local elders and ministerial servants, and while branch offices may appoint regional committees for matters such as Kingdom Hall construction or disaster relief.
How many self-professed "anointed" Jehovah's Witnesses were there as of 2012 in the United States?

QUES: At a certain temperature, (usually between 1,500 °F (820 °C) and 1,600 °F (870 °C), depending on carbon content), the base metal of steel undergoes a change in the arrangement of the atoms in its crystal matrix, called allotropy. This allows the small carbon atoms to enter the interstices of the iron crystal, diffusing into the iron matrix. When this happens, the carbon atoms are said to be in solution, or mixed with the iron, forming a single, homogeneous, crystalline phase called austenite. If the steel is cooled slowly, the iron will gradually change into its low temperature allotrope. When this happens the carbon atoms will no longer be soluble with the iron, and will be forced to precipitate out of solution, nucleating into the spaces between the crystals. The steel then becomes heterogeneous, being formed of two phases; the carbon (carbide) phase cementite, and ferrite. This type of heat treatment produces steel that is rather soft and bendable. However, if the steel is cooled quickly the carbon atoms will not have time to precipitate. When rapidly cooled, a diffusionless (martensite) transformation occurs, in which the carbon atoms become trapped in solution. This causes the iron crystals to deform intrinsically when the crystal structure tries to change to its low temperature state, making it very hard and brittle.
