Q: Extract the answer to the question from the following context. Question: What gave Sony security concerns? Context: The 'OtherOS' functionality was not present in the updated PS Slim models, and the feature was subsequently removed from previous versions of the PS3 as part of the machine's firmware update version 3.21 which was released on April 1, 2010; Sony cited security concerns as the rationale. The firmware update 3.21 was mandatory for access to the PlayStation Network. The removal caused some controversy; as the update removed officially advertised features from already sold products, and gave rise to several class action lawsuits aimed at making Sony return the feature or provide compensation.
A: The 'OtherOS' functionality
Question: Extract the answer to the question from the following context. Question: What gives the Supercapacitors their advantage? Context: Last but not least the electric double-layer capacitor (now Supercapacitors) were invented. In 1957 H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors. Because the double layer mechanism was not known by him at the time, he wrote in the patent: "It is not known exactly what is taking place in the component if it is used for energy storage, but it leads to an extremely high capacity.".
Answer: electric double-layer
[Q]: Extract the answer to the question from the following context. Question: Why were new buildings introduced? Context: The primary responsibility for a boy's studies lies with his House Master, but he is assisted by an additional director of studies, known as a tutor. Classes, colloquially known as "divs" (divisions), are organised on a School basis; the classrooms are separate from the houses. New school buildings have appeared for teaching purposes every decade or so since New Schools, designed by Henry Woodyer and built 1861-3. Despite the introduction of modern technology, the external appearance and locations of many of the classrooms have remained unchanged for a long time.

input: Please answer the following: Extract the answer to the question from the following context. Question: Why might someone call another black? Context: The US racial or ethnic classification "black" refers to people with all possible kinds of skin pigmentation, from the darkest through to the very lightest skin colors, including albinos, if they are believed by others to have West African ancestry (in any discernible percentage), or to exhibit cultural traits associated with being "African American". As a result, in the United States the term "black people" is not an indicator of skin color or ethnic origin but is instead a socially based racial classification related to being African American, with a family history associated with institutionalized slavery. Relatively dark-skinned people can be classified as white if they fulfill other social criteria of "whiteness", and relatively light-skinned people can be classified as black if they fulfill the social criteria for "blackness" in a particular setting.
++++++++++
output: skin pigmentation
Please answer this: Extract the answer to the question from the following context. Question: Slow-draining soil and what other feature causes localized flooding for Houston? Context: Houston has mild winters in contrast to most areas of the United States. In January, the normal mean temperature at Intercontinental Airport is 53.1 F (11.7 C), while that station has an average of 13 days with a low at or below freezing. Snowfall is rare. Recent snow events in Houston include a storm on December 24, 2004 when one inch (2.5 cm) of snow accumulated in parts of the metro area. Falls of at least one inch on both December 10, 2008 and December 4, 2009 marked the first time measurable snowfall had occurred in two consecutive years in the city's recorded history. The coldest temperature officially recorded in Houston was 5 F (15 C) on January 18, 1940. Houston has historically received an ample amount of rainfall, averaging about 49.8 in (1,260 mm) annually per 19812010 normals. Localized flooding often occurs, owing to the extremely flat topography and widespread typical clay-silt prairie soils, which do not drain quickly.

Answer: extremely flat topography
Question: Extract the answer to the question from the following context. Question: Who didn't want the Austrians to retain Glatz? Context: The Treaty of Hubertusburg, between Austria, Prussia, and Saxony, was signed on February 15, 1763, at a hunting lodge between Dresden and Leipzig. Negotiations had started there on December 31, 1762. Frederick, who had considered ceding East Prussia to Russia if Peter III helped him secure Saxony, finally insisted on excluding Russia (in fact, no longer a belligerent) from the negotiations. At the same time, he refused to evacuate Saxony until its elector had renounced any claim to reparation. The Austrians wanted at least to retain Glatz, which they had in fact reconquered, but Frederick would not allow it. The treaty simply restored the status quo of 1748, with Silesia and Glatz reverting to Frederick and Saxony to its own elector. The only concession that Prussia made to Austria was to consent to the election of Archduke Joseph as Holy Roman emperor.
Answer:
Frederick
