Definition: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
Input: original question: What is the roller coaster propulsion system for [SheiKra]?
answer: lift hill
answer type: Roller Coaster Propulsion System.
auxiliary information: SheiKra is a steel Dive Coaster roller coaster at the Busch Gardens Tampa Bay amusement park in Tampa, Florida, United States. The roller coaster was proposed by Mark Rose, vice-president of design and engineering for the park, and designed by Bolliger & Mabillard. The ride was planned to be 160 feet high, but the park's executives rejected this and the height was changed to 200 feet. SheiKra reaches a maximum speed of 70 miles per hour and has a total track length of 3,188 feet. It first opened on May 21, 2005, and was converted to a floorless roller coaster on June 16, 2007, following the opening of its sister Dive Coaster Griffon at Busch Gardens Williamsburg that year. SheiKra was the first Dive Coaster to be constructed in North America; its track includes a splashdown and an Immelmann loop, both a first for its kind. It broke the records for the world's longest, tallest, and fastest Dive Coaster, but lost these records when Griffon in Williamsburg, Virginia, United States and Dive Coaster at Chime-Long Paradise in Guangzhou, China opened. The name SheiKra is derived from the word "shikra", an Asian-African hawk that is known to dive vertically for its prey.
