Instructions: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Input: Passage: Within the Tasmajdan park a sports complex of Tasmajdan Sports Centre is located. Centre administers several facilities located outside Tasmajdan, like "Pionir Hall" and "Ice Hall". However, swimming pools are located in the park. The outdoor swimming pool was built in 1959-1961. Its dimensions are 50 x 20 meters; its depth varies between 2.2 and 5.0 meters; its capacity is 3,500 m and 2,500 seats. Next to the big one, there is a small swimming pool for children. Altogether, there is enough room for 4,000 people. It is equipped for international day-and-night competitions in swimming, water polo, water diving, etc. and also used for certain cultural venues or as an outdoor cinema during summer. It was one of the venues for the 2006 Mens European Water Polo Championship and one of the venues of the 2009 Summer Universiade in July 2009, the event for which the pool was renovated. The indoor swimming-pool was built in 1964-1968. Its dimensions are 50 x 20 meters and depth is between 2.2 and 5.4 meters; its capacity is 3,700 m. The swimming pool is surrounded with four diving boards - 1, 3, 5 and 10 meters high and 2,000 seats. It is equipped with underwater light. At -16 C, water and air can be heated up to 28 C.
Output:
How many meters is the difference between the shallowest depth and the deepest depth of the pool?
