Extract the answer to the question from the following context. Question: What data compression algorithm do AIFFs NOT employ? Context: 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.
Ans: Lossy data compression

Context: In some design instances, materials used on walls and furniture play a key role in the lighting effect< for example dark paint tends to absorb light, making the room appear smaller and more dim than it is, whereas light paint does the opposite.

Extract the answer to the question from the following context. Question: What happened in the 23 year of the 1900s? Context: In 1922, the number of supporters had surpassed 20,000 and by lending money to the club, Barca was able to build the larger Camp de Les Corts, which had an initial capacity of 20,000 spectators. After the Spanish Civil War the club started attracting more members and a larger number of spectators at matches. This led to several expansion projects: the grandstand in 1944, the southern stand in 1946, and finally the northern stand in 1950. After the last expansion, Les Corts could hold 60,000 spectators.
Ans: the number of supporters had surpassed 20,000

Extract the answer to the question from the following context. Question: Who was John's brother? Context: The political turmoil continued. John began to explore an alliance with the French king Philip II, freshly returned from the crusade. John hoped to acquire Normandy, Anjou and the other lands in France held by Richard in exchange for allying himself with Philip. John was persuaded not to pursue an alliance by his mother. Longchamp, who had left England after Walter's intervention, now returned, and argued that he had been wrongly removed as justiciar. John intervened, suppressing Longchamp's claims in return for promises of support from the royal administration, including a reaffirmation of his position as heir to the throne. When Richard still did not return from the crusade, John began to assert that his brother was dead or otherwise permanently lost. Richard had in fact been captured en route to England by the Duke of Austria and was handed over to Emperor Henry VI, who held him for ransom. John seized the opportunity and went to Paris, where he formed an alliance with Philip. He agreed to set aside his wife, Isabella of Gloucester, and marry Philip's sister, Alys, in exchange for Philip's support. Fighting broke out in England between forces loyal to Richard and those being gathered by John. John's military position was weak and he agreed to a truce; in early 1194 the king finally returned to England, and John's remaining forces surrendered. John retreated to Normandy, where Richard finally found him later that year. Richard declared that his younger brother despite being 27 years old was merely "a child who has had evil counsellors" and forgave him, but removed his lands with the exception of Ireland.
Ans: Richard
