input question: Given the following context:  Rolling Stone described "Imagine" as Lennon's "greatest musical gift to the world", praising "the serene melody; the pillowy chord progression; [and] that beckoning, four-note [piano] figure". Robert Christgau called it "both a hymn for the Movement and a love song for his wife, celebrating a Yokoism and a Marcusianism simultaneously". Included in several song polls, in 1999, BMI named it one of the top 100 most-performed songs of the 20th century. Also that year, it received the Grammy Hall of Fame Award and an induction into the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. "Imagine" ranked number 23 in the list of best-selling singles of all time in the UK, in 2000. In 2002, a UK survey conducted by the Guinness World Records British Hit Singles Book ranked it the second best single of all time behind Queen's "Bohemian Rhapsody". Gold Radio ranked the song number three on its "Gold's greatest 1000 hits" list.Rolling Stone ranked "Imagine" number three on its list of "The 500 Greatest Songs of All Time", describing it as "an enduring hymn of solace and promise that has carried us through extreme grief, from the shock of Lennon's own death in 1980 to the unspeakable horror of September 11th. It is now impossible to imagine a world without 'Imagine', and we need it more than he ever dreamed." Despite that sentiment, Clear Channel Communications (now known today as iHeartMedia) included the song on its post-9/11 "do not play" list.On 1 January 2005, the Canadian Broadcasting Corporation named "Imagine" the greatest song in the past 100 years as voted by listeners on the show 50 Tracks.

They voted it eleventh in...  answer the following question:  What was ranked as the second best single of all time in 2002????

Given the following context:  Two kinds of wet prairies thrive in the Everglades: marl and water-marsh community. Wet prairies are slightly elevated like sawgrass marshes, but contain abundant plant diversity.  Marl prairies are located where marl covers limestone that may protrude as pinnacles or erode into solution holes: depressions formed by the same processes that create sinkholes. Solution holes, however, do not meet the water table; they are filled with rain water. The surface is covered only three to seven months of the year, but the water is usually just 4 inches (10 cm) deep. Marl is created by layers of periphyton loosely attached to the limestone, and forms a grey or white crumbly mud when it dries. When flooded, the marl can support a variety of water plants, and dwarf cypresses may grow for hundreds of years though not exceed 10 feet (3.0 m) in height. Solution holes may remain flooded even when the prairies are dry, and they support aquatic invertebrates such as crayfish and snails, as well as larval amphibians which feed young wading birds. Where the predominant soil is peat, a water-marsh community exists. Its hydroperiod is longer than the marl prairie, although its plants are less diverse. These regions tend to be on the border between sloughs and sawgrass marshes. Alligators have created an ecological niche in wet prairies; they dig at low spots with their claws and snouts and create ponds free of vegetation that remain submerged throughout the dry season. Alligator holes are integral to the survival of aquatic invertebrates, turtles, fish, small mammals, and birds during extended drought periods. Alligators feed upon animals that visit the hole.  answer the following question:  What prairies' surface is covered only three to seven months of the year?
----
Answer: Marl prairies

Q: Given the following context:  Following the cover up of a crash of a nuclear bomber at an American Air Force base in the UK, Dennis Markham, a prominent Member of Parliament and opponent of the American nuclear presence in the United Kingdom, is planning to ask questions about it in Parliament. Before he can, he is reported by a London paper to have been seen leaving a woman's home on the same evening as she is visited by a military attache from East Germany, Markham's loyalty to his country is questioned. He is hounded by the media and is forced to resign. The author of the newspaper exposé, Nick Mullen, continues his work alongside colleague Vernon Bayliss who suspects that Markham was framed. When Bayliss dies from a supposed heart attack the same night as Bayliss' flat is ransacked by someone who was not after money or valuables, Mullen suspects something deeper at work. He then finds some evidence of the cover-up of a near-accident at a nuclear site and a secret US Air Force base. With the help of Markham's secretary, Nina Beckman, Mullen continues to investigate the affair despite a break in of his flat, surveillance and other attempts of the British Government to stop him. In the end, Mullen and Beckman are seemingly killed in an explosion, but Mullen's story about the cover-up is published.  answer the following question:  What is the full name of the person Dennis Markham's secretary helped?
A: Nick Mullen

Problem: Given the question: Given the following context:  The hartebeest (; Alcelaphus buselaphus), also known as kongoni, is an African antelope. Eight subspecies have been described, including two sometimes considered to be independent species. A large antelope, the hartebeest stands just over 1 m (3.3 ft) at the shoulder, and has a typical head-and-body length of 200 to 250 cm (79 to 98 in). The weight ranges from 100 to 200 kg (220 to 440 lb). It has a particularly elongated forehead and oddly shaped horns, short neck, and pointed ears. Its legs, which often have black markings, are unusually long. The coat is generally short and shiny. Coat colour varies by the subspecies, from the sandy brown of the western hartebeest to the chocolate brown of the Swayne's hartebeest. Both sexes of all subspecies have horns, with those of females being more slender. Horns can reach lengths of 45–70 cm (18–28 in). Apart from its long face, the large chest and the sharply sloping back differentiate the hartebeest from other antelopes. Gregarious animals, hartebeest form herds of 20 to 300 individuals. They are very alert and non-aggressive. They are primarily grazers, with their diets consisting mainly of grasses. Mating in hartebeest takes place throughout the year with one or two peaks, and depends upon the subspecies and local factors. Both males and females reach sexual maturity at one to two years of age. Gestation is eight to nine months long, after which a single calf is born. Births usually peak in the dry season. The lifespan is 12 to 15 years.  answer the following question:  What is the scientific name of the kongoni?

The answer is:
Alcelaphus buselaphus
