Problem: Steven Spielberg:

Spielberg was born in Cincinnati, Ohio, to an Orthodox Jewish family. His mother, Leah (Adler) Posner (born 1920), was a restaurateur and concert pianist, and his father, Arnold Spielberg (born 1917), was an electrical engineer involved in the development of computers. His paternal grandparents were immigrants from Ukraine who settled in Cincinnati in the first decade of the 1900s. In 1950, his family moved to Haddon Township, New Jersey when his father took a job with RCA. Three years later, the family moved to Phoenix, Arizona.:548 Spielberg attended Hebrew school from 1953 to 1957, in classes taught by Rabbi Albert L. Lewis.

Where did Steven Spielberg's family move to in 1953?

A: Phoenix, Arizona

Problem: The psychoacoustic masking codec was first proposed in 1979, apparently independently, by Manfred R. Schroeder, et al. from Bell Telephone Laboratories, Inc. in Murray Hill, NJ, and M. A. Krasner both in the United States. Krasner was the first to publish and to produce hardware for speech (not usable as music bit compression), but the publication of his results as a relatively obscure Lincoln Laboratory Technical Report did not immediately influence the mainstream of psychoacoustic codec development. Manfred Schroeder was already a well-known and revered figure in the worldwide community of acoustical and electrical engineers, but his paper was not much noticed, since it described negative results due to the particular nature of speech and the linear predictive coding (LPC) gain present in speech. Both Krasner and Schroeder built upon the work performed by Eberhard F. Zwicker in the areas of tuning and masking of critical bands, that in turn built on the fundamental research in the area from Bell Labs of Harvey Fletcher and his collaborators. A wide variety of (mostly perceptual) audio compression algorithms were reported in IEEE's refereed Journal on Selected Areas in Communications. That journal reported in February 1988 on a wide range of established, working audio bit compression technologies, some of them using auditory masking as part of their fundamental design, and several showing real-time hardware implementations.
What does LPC stand for?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Sony officially unveiled PlayStation 3 (then marketed as PLAYSTATION 3) to the public on May 16, 2005, at E3 2005, along with a 'boomerang' shaped prototype design of the Sixaxis controller. A functional version of the system was not present there, nor at the Tokyo Game Show in September 2005, although demonstrations (such as Metal Gear Solid 4: Guns of the Patriots) were held at both events on software development kits and comparable personal computer hardware. Video footage based on the predicted PlayStation 3 specifications was also shown (notably a Final Fantasy VII tech demo).
What was one game Sony debuted on a modified PC so gamers could get a look?
A: Metal Gear Solid 4: Guns of the Patriots

Context and question: The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds. The line following the stem group Sphenacodontia split-off several diverse groups of non-mammalian synapsidssometimes referred to as mammal-like reptilesbefore giving rise to the proto-mammals (Therapsida) in the early Mesozoic era. The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of the non-avian dinosaurs 66 million years ago.
When did sphenacodont pelycosaurs become extinct?
Answer: unanswerable

Question: Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.
Is there an answer to this question: What agricultural crop was farmed in the rich soils on the outlying areas of Houston?

Answer: rice

QUES: Countering Krugman, Peter J. Wallison wrote: "It is not true that every bubbleeven a large bubblehas the potential to cause a financial crisis when it deflates." Wallison notes that other developed countries had "large bubbles during the 19972007 period" but "the losses associated with mortgage delinquencies and defaults when these bubbles deflated were far lower than the losses suffered in the United States when the 19972007 [bubble] deflated." According to Wallison, the reason the U.S. residential housing bubble (as opposed to other types of bubbles) led to financial crisis was that it was supported by a huge number of substandard loans generally with low or no downpayments.

Peter J. Wallison's conclusions regarding the financial crisis are not in agreement with this economist's views?
What is the answer?
