Problem: Montana:

The Desert Land Act of 1877 was passed to allow settlement of arid lands in the west and allotted 640 acres (2.6 km2) to settlers for a fee of $.25 per acre and a promise to irrigate the land. After three years, a fee of one dollar per acre would be paid and the land would be owned by the settler. This act brought mostly cattle and sheep ranchers into Montana, many of whom grazed their herds on the Montana prairie for three years, did little to irrigate the land and then abandoned it without paying the final fees. Some farmers came with the arrival of the Great Northern and Northern Pacific Railroads throughout the 1880s and 1890s, though in relatively small numbers.

How much was the charge per acre at first?
---
A: $.25


Problem: The original Cubist architecture is very rare. There is only one country in the world where Cubism was really applied to architecture – namely Bohemia (today Czech Republic) and especially its capital, Prague. Czech architects were the first and only ones in the world to ever design original Cubist buildings. Cubist architecture flourished for the most part between 1910–1914, but the Cubist or Cubism-influenced buildings were also built after the World War I. After the war, the architectural style called Rondo-Cubism was developed in Prague fusing the Cubist architecture with round shapes.
What was for the form of architectural Cubism in Prague called?
---
Answer: Rondo-Cubism


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The city has many distinct neighborhoods. In addition to Downtown, centered on the central business district and the Green, are the following neighborhoods: the west central neighborhoods of Dixwell and Dwight; the southern neighborhoods of The Hill, historic water-front City Point (or Oyster Point), and the harborside district of Long Wharf; the western neighborhoods of Edgewood, West River, Westville, Amity, and West Rock-Westhills; East Rock, Cedar Hill, Prospect Hill, and Newhallville in the northern side of town; the east central neighborhoods of Mill River and Wooster Square, an Italian-American neighborhood; Fair Haven, an immigrant community located between the Mill and Quinnipiac rivers; Quinnipiac Meadows and Fair Haven Heights across the Quinnipiac River; and facing the eastern side of the harbor, The Annex and East Shore (or Morris Cove).
What is the name of the district nearing the harbor of the city?
A: Long Wharf


Context and question: Compared to children, adolescents are more likely to question others' assertions, and less likely to accept facts as absolute truths. Through experience outside the family circle, they learn that rules they were taught as absolute are in fact relativistic. They begin to differentiate between rules instituted out of common sense—not touching a hot stove—and those that are based on culturally-relative standards (codes of etiquette, not dating until a certain age), a delineation that younger children do not make. This can lead to a period of questioning authority in all domains.
Is not dating until a certain age a common sense or culturally-relative standard?
Answer: culturally-relative


Question: Gothic architecture is a style of architecture that flourished during the high and late medieval period. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. Originating in 12th-century France and lasting into the 16th century, Gothic architecture was known during the period as Opus Francigenum ("French work") with the term Gothic first appearing during the later part of the Renaissance. Its characteristics include the pointed arch, the ribbed vault and the flying buttress. Gothic architecture is most familiar as the architecture of many of the great cathedrals, abbeys and churches of Europe. It is also the architecture of many castles, palaces, town halls, guild halls, universities and to a less prominent extent, private dwellings, such as dorms and rooms.
Is there an answer to this question: What style of architecture did Gothic architecture devolve from?

Answer: unanswerable


QUES: The simplest type of MP3 file uses one bit rate for the entire file: this is known as Constant Bit Rate (CBR) encoding. Using a constant bit rate makes encoding simpler and faster. However, it is also possible to create files where the bit rate changes throughout the file. These are known as Variable Bit Rate (VBR) files. The idea behind this is that, in any piece of audio, some parts will be much easier to compress, such as silence or music containing only a few instruments, while others will be more difficult to compress. So, the overall quality of the file may be increased by using a lower bit rate for the less complex passages and a higher one for the more complex parts. With some encoders, it is possible to specify a given quality, and the encoder will vary the bit rate accordingly. Users who know a particular "quality setting" that is transparent to their ears can use this value when encoding all of their music, and generally speaking not need to worry about performing personal listening tests on each piece of music to determine the correct bit rate.

What value do users need to know when encoding their music to help avoid them having to do tests on each piece of music?
What is the answer?
ANS:
quality setting
