Q: 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.
Passage: The Cavaliers won the Eastern Conference (NBA) in 2006-07 NBA season, 2014-15 NBA season, 2015-16 NBA season, 2016-17 NBA season and 2017-18 NBA season but were defeated in the 2007 NBA Finals by the San Antonio Spurs and 2015 NBA Finals the Golden State Warriors, respectively. The Cavs won the Conference again in 2016 NBA Finals and won their first NBA Championship coming back from a 3-1 deficit, finally defeating the Golden State Warriors. Afterwards, an estimated 1.3 million people attended a parade held in the Cavs honor on June 22, 2016. This was the first time the city had planned for a championship parade in 50 years. Basketball, the Cleveland Rosenblums dominated the original American Basketball League (1925-55) winning three of the first five championships (1926, 1929, 1930), and the Cleveland Pipers, owned by George Steinbrenner, won the American Basketball League (1961-63) championship in 1962.
A:
Before the championship parade in 2016, when had the city planned a championship parade?
