Input: Federalism
Usually, a federation is formed at two levels: the central government and the regions (states, provinces, territories), and little to nothing is said about second or third level administrative political entities. Brazil is an exception, because the 1988 Constitution included the municipalities as autonomous political entities making the federation tripartite, encompassing the Union, the States, and the municipalities. Each state is divided into municipalities (municípios) with their own legislative council (câmara de vereadores) and a mayor (prefeito), which are partly autonomous from both Federal and State Government. Each municipality has a "little constitution", called "organic law" (lei orgânica). Mexico is an intermediate case, in that municipalities are granted full-autonomy by the federal constitution and their existence as autonomous entities (municipio libre, "free municipality") is established by the federal government and cannot be revoked by the states' constitutions. Moreover, the federal constitution determines which powers and competencies belong exclusively to the municipalities and not to the constituent states. However, municipalities do not have an elected legislative assembly.

What two levels equal a federation?
Output: the central government and the regions

Input: Data compression
The majority of video compression algorithms use lossy compression. Uncompressed video requires a very high data rate. Although lossless video compression codecs perform at a compression factor of 5-12, a typical MPEG-4 lossy compression video has a compression factor between 20 and 200. As in all lossy compression, there is a trade-off between video quality, cost of processing the compression and decompression, and system requirements. Highly compressed video may present visible or distracting artifacts.

What requires a high data rate?
Output: Uncompressed video

Input: PlayStation 3
PS3 was given the number-eight spot on PC World magazine's list of "The Top 21 Tech Screwups of 2006", where it was criticized for being "Late, Expensive and Incompatible". GamesRadar ranked PS3 as the top item in a feature on game-related PR disasters, asking how Sony managed to "take one of the most anticipated game systems of all time and — within the space of a year — turn it into a hate object reviled by the entire internet", but added that despite its problems the system has "untapped potential". Business Week summed up the general opinion by stating that it was "more impressed with what [the PlayStation 3] could do than with what it currently does".

What gaming website called PS3 "a hate object reviled by the entire internet"?
Output: GamesRadar

Input: Race (human categorization)
Criminal justice agencies in England and Wales use at least two separate racial/ethnic classification systems when reporting crime, as of 2010. One is the system used in the 2001 Census when individuals identify themselves as belonging to a particular ethnic group: W1 (White-British), W2 (White-Irish), W9 (Any other white background); M1 (White and black Caribbean), M2 (White and black African), M3 (White and Asian), M9 (Any other mixed background); A1 (Asian-Indian), A2 (Asian-Pakistani), A3 (Asian-Bangladeshi), A9 (Any other Asian background); B1 (Black Caribbean), B2 (Black African), B3 (Any other black background); O1 (Chinese), O9 (Any other). The other is categories used by the police when they visually identify someone as belonging to an ethnic group, e.g. at the time of a stop and search or an arrest: White – North European (IC1), White – South European (IC2), Black (IC3), Asian (IC4), Chinese, Japanese, or South East Asian (IC5), Middle Eastern (IC6), and Unknown (IC0). "IC" stands for "Identification Code;" these items are also referred to as Phoenix classifications. Officers are instructed to "record the response that has been given" even if the person gives an answer which may be incorrect; their own perception of the person's ethnic background is recorded separately. Comparability of the information being recorded by officers was brought into question by the Office for National Statistics (ONS) in September 2007, as part of its Equality Data Review; one problem cited was the number of reports that contained an ethnicity of "Not Stated."

What does IC stand for?
Output:
Identification Code
