Q: Question: "Killer whales are classified in which taxonomy order?"  Context: "Cetaceans were historically abundant around the island as commercial hunts on the island was operating until 1956. Today, numbers of larger whales have disappeared, but even today many species such humpback whale, minke whale, sei whale, and dolphins can be observed close to shores, and scientific surveys have been conducted regularly. Southern right whales were once regular migrants to the Norfolk hence naming the island as the "Middle ground" by whalers, but had been severely depleted by historical hunts, and further by illegal Soviet and Japan whaling, resulting in none of very few, if remnants still live, right whales in these regions along with Lord Howe Island."  Answer:
A: Cetaceans

Q: Question: "What were researchers looking for?"  Context: "There is some evidence, in the form of ice cores drilled to about 400 m (1,300 ft) above the water line, that Lake Vostok's waters may contain microbial life. The frozen surface of the lake shares similarities with Jupiter's moon, Europa. If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. On 7 February 2008, a NASA team embarked on a mission to Lake Untersee, searching for extremophiles in its highly alkaline waters. If found, these resilient creatures could further bolster the argument for extraterrestrial life in extremely cold, methane-rich environments."  Answer:
A: microbial life

Q: Question: "Which happened first, Kathy Kozachenko's victory in an Ann Arbor city-council race or voters approving charter amendments that aim to protect access to abortion?"  Context: "Left-wing politics have been particularly strong in municipal government since the 1960s. Voters approved charter amendments that have lessened the penalties for possession of marijuana (1974), and that aim to protect access to abortion in the city should it ever become illegal in the State of Michigan (1990). In 1974, Kathy Kozachenko's victory in an Ann Arbor city-council race made her the country's first openly homosexual candidate to win public office. In 1975, Ann Arbor became the first U.S. city to use instant-runoff voting for a mayoral race. Adopted through a ballot initiative sponsored by the local Human Rights Party, which feared a splintering of the liberal vote, the process was repealed in 1976 after use in only one election. As of August 2009, Democrats hold the mayorship and all council seats. The left tilt of politics in the city has earned it the nickname "The People's Republic of Ann Arbor". Nationally, Ann Arbor is located in Michigan's 12th congressional district, represented by Democrat Debbie Dingell."  Answer:
A: Kathy Kozachenko's victory in an Ann Arbor city-council race
