Problem: Data compression:

Lossy data compression is the converse of lossless data compression. In these schemes, some loss of information is acceptable. Dropping nonessential detail from the data source can save storage space. Lossy data compression schemes are designed by research on how people perceive the data in question. For example, the human eye is more sensitive to subtle variations in luminance than it is to the variations in color. JPEG image compression works in part by rounding off nonessential bits of information. There is a corresponding trade-off between preserving information and reducing size. A number of popular compression formats exploit these perceptual differences, including those used in music files, images, and video.

Problem: On November 6, 2006, Microsoft announced the Xbox Video Marketplace, an exclusive video store accessible through the console. Launched in the United States on November 22, 2006, the first anniversary of the Xbox 360's launch, the service allows users in the United States to download high-definition and standard-definition television shows and movies onto an Xbox 360 console for viewing. With the exception of short clips, content is not currently available for streaming, and must be downloaded. Movies are also available for rental. They expire in 14 days after download or at the end of the first 24 hours after the movie has begun playing, whichever comes first. Television episodes can be purchased to own, and are transferable to an unlimited number of consoles. Downloaded files use 5.1 surround audio and are encoded using VC-1 for video at 720p, with a bitrate of 6.8 Mbit/s. Television content is offered from MTV, VH1, Comedy Central, Turner Broadcasting, and CBS; and movie content is Warner Bros., Paramount, and Disney, along with other publishers.
When was Video Marketplace released outside of the US?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
As of 2010, those of (non-Hispanic white) European ancestry accounted for 57.9% of Florida's population. Out of the 57.9%, the largest groups were 12.0% German (2,212,391), 10.7% Irish (1,979,058), 8.8% English (1,629,832), 6.6% Italian (1,215,242), 2.8% Polish (511,229), and 2.7% French (504,641). White Americans of all European backgrounds are present in all areas of the state. In 1970, non-Hispanic whites were nearly 80% of Florida's population. Those of English and Irish ancestry are present in large numbers in all the urban/suburban areas across the state. Some native white Floridians, especially those who have descended from long-time Florida families, may refer to themselves as "Florida crackers"; others see the term as a derogatory one. Like whites in most of the other Southern states, they descend mainly from English and Scots-Irish settlers, as well as some other British American settlers.
What do non-native Floridians call themselves?
A: unanswerable

Context and question: The city grew as the population did, coming up against the lake's waters. As the depth of the lake water fluctuated, Mexico City was subject to periodic flooding. A major labor draft, the desague, compelled thousands of Indians over the colonial period to work on infrastructure to prevent flooding. Floods were not only an inconvenience but also a health hazard, since during flood periods human waste polluted the city's streets. By draining the area, the mosquito population dropped as did the frequency of the diseases they spread. However, draining the wetlands also changed the habitat for fish and birds and the areas accessible for Indian cultivation close to the capital.
What was the labor draft called?
Answer: the desague

Question: A major feature is the calypso competition. Calypso music, originating in Trinidad, uses syncopated rhythm and topical lyrics. It offers a medium in which to satirise local politics, amidst the general bacchanal. Calypso tents, also originating in Trinidad, feature cadres of musicians who perform biting social commentaries, political exposes or rousing exhortations to "wuk dah waistline" and "roll dat bumper". The groups compete for the Calypso Monarch Award, while the air is redolent with the smells of Bajan cooking during the Bridgetown Market Street Fair. The Cohobblopot Festival blends dance, drama and music with the crowning of the King and Queen of costume bands. Every evening the "Pic-o-de-Crop" Show is performed after the King of Calypso is finally crowned. The climax of the festival is Kadooment Day celebrated with a national holiday when costume bands fill the streets with pulsating Barbadian rhythms and fireworks.
Is there an answer to this question: What type of competition is a major feature of the festival?

Answer: calypso

QUES: Most mammals are viviparous, giving birth to live young. However, the five species of monotreme, the platypuses and the echidnas, lay eggs. The monotremes have a sex determination system different from that of most other mammals. In particular, the sex chromosomes of a platypus are more like those of a chicken than those of a therian mammal. Like marsupials and most other mammals, monotreme young are larval and fetus-like, as the presence of epipubic bones prevents the expansion of the torso, forcing them to produce small young.

What are some characteristics of young chickens?
