Problem: Incandescent light bulb:

In flood lamps used for photographic lighting, the tradeoff is made in the other direction. Compared to general-service bulbs, for the same power, these bulbs produce far more light, and (more importantly) light at a higher color temperature, at the expense of greatly reduced life (which may be as short as two hours for a type P1 lamp). The upper temperature limit for the filament is the melting point of the metal. Tungsten is the metal with the highest melting point, 3,695 K (6,191 °F). A 50-hour-life projection bulb, for instance, is designed to operate only 50 °C (122 °F) below that melting point. Such a lamp may achieve up to 22 lumens per watt, compared with 17.5 for a 750-hour general service lamp.

Which metal has the highest melting point?

A: Tungsten


Problem: The earliest known use of the phrase Brytish Iles in the English language is dated 1577 in a work by John Dee. Today, this name is seen by some as carrying imperialist overtones although it is still commonly used. Other names used to describe the islands include the Anglo-Celtic Isles, Atlantic archipelago, British-Irish Isles, Britain and Ireland, UK and Ireland, and British Isles and Ireland. Owing to political and national associations with the word British, the Government of Ireland does not use the term British Isles and in documents drawn up jointly between the British and Irish governments, the archipelago is referred to simply as "these islands". Nonetheless, British Isles is still the most widely accepted term for the archipelago.
What are some other names used to describe the phrases?

The Gateway Center at Bronx Terminal Market, in the West Bronx, is a shopping center that encompasses less than one million square feet of retail space, built on a 17 acres (7 ha) site that formerly held the Bronx Terminal Market, a wholesale fruit and vegetable market as well as the former Bronx House of Detention, south of Yankee Stadium. The $500 million shopping center, which was completed in 2009, saw the construction of new buildings and two smaller buildings, one new and the other a renovation of an existing building that was part of the original market. The two main buildings are linked by a six-level garage for 2,600 cars. The center has earned itself a LEED "Silver" designation in its design.
How much did the Gateway Center at Bronx Terminal Market cost?
A: $500 million


Context and question: On 3 November 2007, the Sichuan Transportation Bureau announced that the Sui-Yu Expressway was completed after three years of construction. After completion of the Chongqing section of the road, the 36.64 km (22.77 mi) expressway connected Cheng-Nan Expressway and formed the shortest expressway from Chengdu to Chongqing. The new expressway is 50 km (31 mi) shorter than the pre-existing road between Chengdu and Chongqing; thus journey time between the two cities was reduced by an hour, now taking two and a half hours. The Sui-Yu Expressway is a four lane overpass with a speed limit of 80 km/h (50 mph). The total investment was 1.045 billion yuan.
What was the longest espressway from Chengdu to Chongqing?
Answer: unanswerable


Question: Soteriologically, most Methodists are Arminian, emphasizing that Christ accomplished salvation for every human being, and that humans must exercise an act of the will to receive it (as opposed to the traditional Calvinist doctrine of monergism). Methodism is traditionally low church in liturgy, although this varies greatly between individual congregations; the Wesleys themselves greatly valued the Anglican liturgy and tradition. Methodism is known for its rich musical tradition; John Wesley's brother, Charles, was instrumental in writing much of the hymnody of the Methodist Church, and many other eminent hymn writers come from the Methodist tradition.
Is there an answer to this question: Who wrote most of the Methodist hymns?

Answer: John Wesley's brother, Charles

Poetry is a form of literary art which uses aesthetic and rhythmic qualities of language to evoke meanings in addition to, or in place of, prosaic ostensible meaning. Poetry has traditionally been distinguished from prose by its being set in verse;[a] prose is cast in sentences, poetry in lines; the syntax of prose is dictated by meaning, whereas that of poetry is held across metre or the visual aspects of the poem. Prior to the nineteenth century, poetry was commonly understood to be something set in metrical lines; accordingly, in 1658 a definition of poetry is "any kind of subject consisting of Rythm or Verses". Possibly as a result of Aristotle's influence (his Poetics), "poetry" before the nineteenth century was usually less a technical designation for verse than a normative category of fictive or rhetorical art. As a form it may pre-date literacy, with the earliest works being composed within and sustained by an oral tradition; hence it constitutes the earliest example of literature.
What elements of language make for poetic literature?
A:
aesthetic and rhythmic qualities
