Problem: Question: "what do codecs do" Context: "Latency results from the methods used to encode and decode the data. Some codecs will analyze a longer segment of the data to optimize efficiency, and then code it in a manner that requires a larger segment of data at one time to decode. (Often codecs create segments called a "frame" to create discrete data segments for encoding and decoding.) The inherent latency of the coding algorithm can be critical; for example, when there is a two-way transmission of data, such as with a telephone conversation, significant delays may seriously degrade the perceived quality." Answer:

A: used to encode and decode the data

Problem: Question: "Which event occurred first, the signing of the Anglo-Russian Entente or the Russo-Japanese War?" Context: "When Russia invaded the Turkish Balkans in 1853, fears of Russian dominance in the Mediterranean and Middle East led Britain and France to invade the Crimean Peninsula to destroy Russian naval capabilities. The ensuing Crimean War (185456), which involved new techniques of modern warfare, and was the only global war fought between Britain and another imperial power during the Pax Britannica, was a resounding defeat for Russia. The situation remained unresolved in Central Asia for two more decades, with Britain annexing Baluchistan in 1876 and Russia annexing Kirghizia, Kazakhstan, and Turkmenistan. For a while it appeared that another war would be inevitable, but the two countries reached an agreement on their respective spheres of influence in the region in 1878 and on all outstanding matters in 1907 with the signing of the Anglo-Russian Entente. The destruction of the Russian Navy by the Japanese at the Battle of Port Arthur during the Russo-Japanese War of 190405 also limited its threat to the British." Answer:

A: Russo-Japanese War

Problem: Question: "Which of the following is not a notable song that originated in Montevideo: La Cumparsita, La Punalada, or tango?" Context: "In Montevideo, as throughout the Rio de Plata region, the most popular forms of music are tango, milonga and vals criollo. Many notable songs originated in Montevideo including "El Tango supremo", La Cumparsita", La Milonga", "La Punalada" and "Desde el Alma", composed by notable Montevideo musicians such as Gerardo Matos Rodriguez, Pintin Castellanos and Rosita Melo. Tango is deeply ingrained in the cultural life of the city and is the theme for many of the bars and restaurants in the city. Fun Fun' Bar, established in 1935, is one of the most important places for tango in Uruguay as is El Farolito, located in the old part of the city and Joventango, Cafe Las Musas, Garufa and Vieja Viola. The city is also home to the Montevideo Jazz Festival and has the Bancaria Jazz Club bar catering for jazz enthusiasts." Answer:

A: tango

Problem: Question: "What did this model show?" Context: "Instead, he formulated the spearhead model of evolution, a version of genetic pluralism. According to this model, living organisms themselves have goals, and act according to these goals, each guided by a central control. In its most sophisticated form, this is the brain of humans, but controls also exist in much less sophisticated ways for species of lower complexity, such as the amoeba. This control organ plays a special role in evolutionit is the "spearhead of evolution". The goals bring the purpose into the world. Mutations in the genes that determine the structure of the control may then cause drastic changes in behaviour, preferences and goals, without having an impact on the organism's phenotype. Popper postulates that such purely behavioural changes are less likely to be lethal for the organism compared to drastic changes of the phenotype." Answer:

A:
evolution
