Problem: Hard rock:

The term "retro-metal" has been applied to such bands as Texas based The Sword, California's High on Fire, Sweden's Witchcraft and Australia's Wolfmother. Wolfmother's self-titled 2005 debut album combined elements of the sounds of Deep Purple and Led Zeppelin. Fellow Australians Airbourne's debut album Runnin' Wild (2007) followed in the hard riffing tradition of AC/DC. England's The Darkness' Permission to Land (2003), described as an "eerily realistic simulation of '80s metal and '70s glam", topped the UK charts, going quintuple platinum. The follow-up, One Way Ticket to Hell... and Back (2005), reached number 11, before the band broke up in 2006. Los Angeles band Steel Panther managed to gain a following by sending up 80s glam metal. A more serious attempt to revive glam metal was made by bands of the sleaze metal movement in Sweden, including Vains of Jenna, Hardcore Superstar and Crashdiet.

What album from 2003 was described as a simulation of 70s metal and 80s glam?

A: unanswerable

Problem: His opponents have attacked Hayek as a leading promoter of "neoliberalism". A British scholar, Samuel Brittan, concluded in 2010, "Hayek's book [The Constitution of Liberty] is still probably the most comprehensive statement of the underlying ideas of the moderate free market philosophy espoused by neoliberals." Brittan adds that although Raymond Plant (2009) comes out in the end against Hayek's doctrines, Plant gives The Constitution of Liberty a "more thorough and fair-minded analysis than it has received even from its professed adherents".
Whose ideals does Brittan believe to win out over Hayek's?

Answer: Raymond Plant

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Media requests at the trade show prompted Kondo to consider using orchestral music for the other tracks in the game as well, a notion reinforced by his preference for live instruments. He originally envisioned a full 50-person orchestra for action sequences and a string quartet for more "lyrical moments", though the final product used sequenced music instead. Kondo later cited the lack of interactivity that comes with orchestral music as one of the main reasons for the decision. Both six- and seven-track versions of the game's soundtrack were released on November 19, 2006, as part of a Nintendo Power promotion and bundled with replicas of the Master Sword and the Hylian Shield.
What kind of instruments are favored by Hylian?
A: unanswerable

Context and question: Antarctica has no indigenous population and there is no evidence that it was seen by humans until the 19th century. However, belief in the existence of a Terra Australisa vast continent in the far south of the globe to "balance" the northern lands of Europe, Asia and North Africahad existed since the times of Ptolemy (1st century AD), who suggested the idea to preserve the symmetry of all known landmasses in the world. Even in the late 17th century, after explorers had found that South America and Australia were not part of the fabled "Antarctica", geographers believed that the continent was much larger than its actual size.
Early geographers thought that Antarctica was what in size?
Answer: larger

Question: Elizabeth was born in London to the Duke and Duchess of York, later King George VI and Queen Elizabeth, and was the elder of their two daughters. She was educated privately at home. Her father acceded to the throne on the abdication of his brother Edward VIII in 1936, from which time she was the heir presumptive. She began to undertake public duties during World War II, serving in the Auxiliary Territorial Service. In 1947, she married Philip, Duke of Edinburgh, with whom she has four children: Charles, Anne, Andrew, and Edward.
Is there an answer to this question: In what year was Edward born?

Answer: unanswerable

QUES: Time appears to have a directionthe past lies behind, fixed and immutable, while the future lies ahead and is not necessarily fixed. Yet for the most part the laws of physics do not specify an arrow of time, and allow any process to proceed both forward and in reverse. This is generally a consequence of time being modeled by a parameter in the system being analyzed, where there is no "proper time": the direction of the arrow of time is sometimes arbitrary. Examples of this include the Second law of thermodynamics, which states that entropy must increase over time (see Entropy); the cosmological arrow of time, which points away from the Big Bang, CPT symmetry, and the radiative arrow of time, caused by light only traveling forwards in time (see light cone). In particle physics, the violation of CP symmetry implies that there should be a small counterbalancing time asymmetry to preserve CPT symmetry as stated above. The standard description of measurement in quantum mechanics is also time asymmetric (see Measurement in quantum mechanics).

Which law states that entropy must increase in the past?
