Input: Read this: Elementary and secondary public schools are overseen by the North Carolina Department of Public Instruction. The North Carolina Superintendent of Public Instruction is the secretary of the North Carolina State Board of Education, but the board, rather than the superintendent, holds most of the legal authority for making public education policy. In 2009, the board's chairman also became the "chief executive officer" for the state's school system. North Carolina has 115 public school systems, each of which is overseen by a local school board. A county may have one or more systems within it. The largest school systems in North Carolina are the Wake County Public School System, Charlotte-Mecklenburg Schools, Guilford County Schools, Winston-Salem/Forsyth County Schools, and Cumberland County Schools. In total there are 2,425 public schools in the state, including 99 charter schools. North Carolina Schools were segregated until the Brown v. Board of Education trial and the release of the Pearsall Plan.
Question: What year did the boards chairman become the Chief Executive officer of public schools?

Output: 2009

QUES: As the initial punk movement dwindled, vibrant new scenes began to coalesce out of a variety of bands pursuing experimental sounds and wider conceptual territory in their work. Many of these artists drew on backgrounds in art and viewed their music as invested in particular political or aesthetic agendas. British music publications such as the NME and Sounds developed an influential part in this nascent post-punk culture, with writers like Jon Savage, Paul Morley and Ian Penman developing a dense (and often playful) style of criticism that drew on critical theory, radical politics and an eclectic variety of other sources.

What styles of criticism were not used by writers?
What is the answer?
ANS: unanswerable

QUES: Friedrich Nietzsche argued that Kant commits an agnostic tautology and does not offer a satisfactory answer as to the source of a philosophical right to such-or-other metaphysical claims; he ridicules his pride in tackling "the most difficult thing that could ever be undertaken on behalf of metaphysics." The famous "thing-in-itself" was called a product of philosophical habit, which seeks to introduce a grammatical subject: because wherever there is cognition, there must be a thing that is cognized and allegedly it must be added to ontology as a being (whereas, to Nietzsche, only the world as ever changing appearances can be assumed). Yet he attacks the idealism of Schopenhauer and Descartes with an argument similar to Kant's critique of the latter (see above).
Nietzsche's attack on Schopenhauer used an argument similar to Kant's attack on who?

ANS: Descartes

Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What variables help the photographer produce the desired effect?
Ah, so.. lighting, film speed, f-number (aperture size), and shutter speed (exposure time)

Question: 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.
Try to answer this question if possible: What is the lowland area of Tennessee between the Tennessee River and Mississippi River called?
Answer: Tennessee Bottoms

Context and question: The British Library notes that "Chopin's works have been recorded by all the great pianists of the recording era." The earliest recording was an 1895 performance by Paul Pabst of the Nocturne in E major Op. 62 No. 2. The British Library site makes available a number of historic recordings, including some by Alfred Cortot, Ignaz Friedman, Vladimir Horowitz, Benno Moiseiwitsch, Paderewski, Arthur Rubinstein, Xaver Scharwenka and many others. A select discography of recordings of Chopin works by pianists representing the various pedagogic traditions stemming from Chopin is given by Methuen-Campbell in his work tracing the lineage and character of those traditions.
Who has given a discography of pianists' representation of Chopin's pedagogic style?
Answer:
Methuen-Campbell
