Extract the answer to the question from the following context. Question: What is Red knots Calidris canutus? Context: Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V-formation may conserve 12–20% of the energy they would need to fly alone. Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (3.1 mph) faster in flocks than when they were flying alone.
Ans: birds

Extract the answer to the question from the following context. Question: What made a new group of people appreciate and listen to West's music? Context: The College Dropout was eventually issued by Roc-A-Fella in February 2004, shooting to number two on the Billboard 200 as his debut single, "Through the Wire" peaked at number fifteen on the Billboard Hot 100 chart for five weeks. "Slow Jamz", his second single featuring Twista and Jamie Foxx, became an even bigger success: it became the three musicians' first number one hit. The College Dropout received near-universal critical acclaim from contemporary music critics, was voted the top album of the year by two major music publications, and has consistently been ranked among the great hip-hop works and debut albums by artists. "Jesus Walks", the album's fourth single, perhaps exposed West to a wider audience; the song's subject matter concerns faith and Christianity. The song nevertheless reached the top 20 of the Billboard pop charts, despite industry executives' predictions that a song containing such blatant declarations of faith would never make it to radio. The College Dropout would eventually be certified triple platinum in the US, and garnered West 10 Grammy nominations, including Album of the Year, and Best Rap Album (which it received). During this period, West also founded GOOD Music, a record label and management company that would go on to house affiliate artists and producers, such as No I.D. and John Legend. At the time, the focal point of West's production style was the use of sped-up vocal samples from soul records. However, partly because of the acclaim of The College Dropout, such sampling had been much copied by others; with that overuse, and also because West felt he had become too dependent on the technique, he decided to find a new sound.
Ans: "Jesus Walks"

Extract the answer to the question from the following context. Question: What allows them to recognize distinct cultures? Context: Where every component state of a federation possesses the same powers, we are said to find 'symmetric federalism'. Asymmetric federalism exists where states are granted different powers, or some possess greater autonomy than others do. This is often done in recognition of the existence of a distinct culture in a particular region or regions. In Spain, the Basques and Catalans, as well as the Galicians, spearheaded a historic movement to have their national specificity recognized, crystallizing in the "historical communities" such as Navarre, Galicia, Catalonia, and the Basque Country. They have more powers than the later expanded arrangement for other Spanish regions, or the Spain of the autonomous communities (called also the "coffee for everyone" arrangement), partly to deal with their separate identity and to appease peripheral nationalist leanings, partly out of respect to specific rights they had held earlier in history. However, strictly speaking Spain is not a federalism, but a decentralized administrative organization of the state.
Ans: autonomy

Extract the answer to the question from the following context. Question: What was prior to the 80s? Context: After the establishment of Hampshire County Council, following the act in 1888, Southampton became a county borough within the county of Hampshire, which meant that it had many features of a county, but governance was now shared between the Corporation in Southampton and the new county council. There is a great source of confusion in the fact that the ancient shire county, along with its associated assizes, was known as the County of Southampton or Southamptonshire. This was officially changed to Hampshire in 1959 although the county had been commonly known as Hampshire or Hantscire for centuries. Southampton became a non-metropolitan district in 1974.
Ans: Southampton became a non-metropolitan district
