Problem: Tennessee:

The easternmost section, about 10 miles (16 km) in width, consists of hilly land that runs along the western bank of the Tennessee River. To the west of this narrow strip of land is a wide area of rolling hills and streams that stretches all the way to the Mississippi River; this area is called the Tennessee Bottoms or bottom land. In Memphis, the Tennessee Bottoms end in steep bluffs overlooking the river. To the west of the Tennessee Bottoms is the Mississippi Alluvial Plain, less than 300 feet (90 m) above sea level. This area of lowlands, flood plains, and swamp land is sometimes referred to as the Delta region. Memphis is the economic center of West Tennessee and the largest city in the state.

What is the lowland area of Tennessee between the Tennessee River and Mississippi River called?

A: Tennessee Bottoms


Problem: Liverpool produced a number of nationally and internationally successful popular singers in the 1950s, including traditional pop stars Frankie Vaughan and Lita Roza, and one of the most successful British rock and roll stars in Billy Fury. Many Lancashire towns had vibrant skiffle scenes in the late 1950s, out of which by the early 1960s a flourishing culture of beat groups began to emerge, particularly around Liverpool and Manchester. It has been estimated that there were around 350 bands active in and around Liverpool in this era, often playing ballrooms, concert halls and clubs, among them the Beatles. After their national success from 1962, a number of Liverpool performers were able to follow them into the charts, including Gerry & the Pacemakers, the Searchers and Cilla Black. The first act to break through in the UK who were not from Liverpool, or managed by Brian Epstein, were Freddie and the Dreamers, who were based in Manchester, as were Herman's Hermits and the Hollies. Led by the Beatles, beat groups from the region spearheaded the British Invasion of the US, which made a major contribution to the development of rock music. After the decline of beat groups in the late 1960s the centre of rock culture shifted to London and there were relatively few local bands who achieved national prominence until the growth of a disco funk scene and the punk rock revolution in the mid and late 1970s.
How many bands were active in the Liverpool area in the 1960s?

Answer: 350


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The MPEG-1 standard does not include a precise specification for an MP3 encoder, but does provide example psychoacoustic models, rate loop, and the like in the non-normative part of the original standard. At present, these suggested implementations are quite dated. Implementers of the standard were supposed to devise their own algorithms suitable for removing parts of the information from the audio input. As a result, there are many different MP3 encoders available, each producing files of differing quality. Comparisons are widely available, so it is easy for a prospective user of an encoder to research the best choice. An encoder that is proficient at encoding at higher bit rates (such as LAME) is not necessarily as good at lower bit rates.
What were implementers of the standard supposed to devise?
A: their own algorithms


Context and question: A much smaller number of people are insensitive to pain due to an inborn abnormality of the nervous system, known as "congenital insensitivity to pain". Children with this condition incur carelessly-repeated damage to their tongues, eyes, joints, skin, and muscles. Some die before adulthood, and others have a reduced life expectancy.[citation needed] Most people with congenital insensitivity to pain have one of five hereditary sensory and autonomic neuropathies (which includes familial dysautonomia and congenital insensitivity to pain with anhidrosis). These conditions feature decreased sensitivity to pain together with other neurological abnormalities, particularly of the autonomic nervous system. A very rare syndrome with isolated congenital insensitivity to pain has been linked with mutations in the SCN9A gene, which codes for a sodium channel (Nav1.7) necessary in conducting pain nerve stimuli.
What is it known as when someone is born without being able to feel pain because of their nervous system?
Answer: congenital insensitivity to pain


Question: The Bronx has also become home to a peculiar poetic tribute, in the form of the Heinrich Heine Memorial, better known as the Lorelei Fountain from one of Heine's best-known works (1838). After Heine's German birthplace of Düsseldorf had rejected, allegedly for anti-Semitic motives, a centennial monument to the radical German-Jewish poet (1797–1856), his incensed German-American admirers, including Carl Schurz, started a movement to place one instead in Midtown Manhattan, at Fifth Avenue and 59th Street. However, this intention was thwarted by a combination of ethnic antagonism, aesthetic controversy and political struggles over the institutional control of public art.
Is there an answer to this question: What ethnicity is Carl Schurz?

Answer: German-American


Copper's greater conductivity versus other metals enhances the electrical energy efficiency of motors. This is important because motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Increasing the mass and cross section of copper in a coil increases the electrical energy efficiency of the motor. Copper motor rotors, a new technology designed for motor applications where energy savings are prime design objectives, are enabling general-purpose induction motors to meet and exceed National Electrical Manufacturers Association (NEMA) premium efficiency standards.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What property of copper increases the efficiency of electrical motors?
Ah, so..
conductivity
