instruction:
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.
question:
Passage: Johann Bayer used the Greek letters Alpha to Eta to label the most prominent eight stars in the constellation, designating two stars as Delta (named Delta1 and Delta2). John Flamsteed numbered fourteen stars, discerning a third star he named Delta3; his star 12 Canis Minoris was not found subsequently. In Bayers 1603 work Uranometria, Procyon is located on the dogs belly, and Gomeisa on its neck. Gamma Canis Minoris, Epsilon Canis Minoris and Eta Canis Minoris lie nearby, marking the dogs neck, crown and chest respectively. Although it has an apparent magnitude of 4.34, Gamma Canis Minoris is an orange stellar classification giant star of spectral class K3-III C, which lies  away. Its colour is obvious when seen through binoculars. It is a multiple system, consisting of the  spectroscopic binary Gamma A and three optical companions, Gamma B, magnitude 13; Gamma C, magnitude 12; and Gamma D, magnitude 10. The two components of Gamma A orbit each other every 389.2 days, with an eccentric orbit that takes their separation between 2.3 and 1.4 astronomical units (AU). Epsilon Canis Minoris is a yellow bright giant of spectral class G6.5IIb of magnitude of 4.99. It lies  from Earth, with 13 times the diameter and 750 times the luminosity of the Sun. Eta Canis Minoris is a giant of spectral class F0III of magnitude 5.24, which has a yellowish hue when viewed through binoculars as well as a faint companion of magnitude 11.1. Located 4 arcseconds from the primary, the companion star is actually around 440 AU from the main star and takes around 5000 years to orbit it.
answer:
How many Delta stars have been designated?


question:
Passage: With the rest of Week 16's games being played on Christmas Eve, the Jets, due to losses by Jacksonville and Cincinnati, controlled their own playoff destiny with two victories. The game was played in a driving rainstorm as both teams struggled to move the ball early. With 49 seconds remaining in the first quarter, Mike Nugent was ready to attempt a 34-yard field goal, but holder Ben Graham could not handle the snap in the slippery conditions, and the Jets were denied. It was the second straight week Graham had flubbed a snap, but this one could be blamed on the wet conditions. The two teams would trade punts for the rest of the half. In the third quarter, Dolphins coach Nick Saban inserted backup quarterback Cleo Lemon into the game, replacing an ineffective Joey Harrington. Finally, the Jets went on a drive with 6:15 left in the third quarter, with Chad Pennington scrambling for 15 yards and moving into the Dolphins' red zone when Yeremiah Bell was flagged for pass interference. Nugent knocked in a 22-yard field goal for the first points of the game. But Lemon rallied Miami, completing two long passes to Randy McMichael and Ronnie Brown picking up a long run before Lemon tossed a 7-yard touchdown pass to McMichael, and the Dolphins led 7-3 with 13:26 left in the game. Pennington showed poise in leading the Jets back to take the lead, completing key passes to Brad Smith and Leon Washington before finding Cotchery on a 31-yard completion to the Miami 1-yard line, but the Jets challenged, saying that Cotchery was brought down after he broke the plane of the end zone, and the referee agreed, giving the Jets a 10-7 lead with 8:04 remaining in the game. Miami was then forced to punt, but caught a break when Donnie Jones' kick bounced off the elbow of Jets linebacker Brad Kassell, and long snapper John Denney recovered at the Jets' 42-yard line. Lemon led Miami downfield, completing key passes to Derek Hagan and Sammy Morris before Mare tied the game with a 25-yard field goal. With 2:09 to play, the Jets' biggest play of the season took place. Pennington flipped a short screen pass to Washington, who found a hole and scampered 64 yards down to the Miami 16-yard line. After three runs by Kevan Barlow, Nugent kicked a 30-yard field goal with 10 seconds to play, and the Jets had their biggest win of the year.
answer:
how many yards did Cotchery complete?


question:
Passage: World Expos are also massive in scale, sometimes 300 or 400 hectares in size (Montreals Expo 67 was 410 hectares, Osakas Expo 70 was 330 hectares, Sevilles Seville Expo 92 was 215 hectares and Shanghais Expo 2010, 528 hectares). Pavilions participating at a World Expo can also be large, sometimes 5,000 to 10,000 square metres in size, mini city blocks in themselves and sometimes more than several stories in height. (The Australia Pavilion for Shanghai 2010 was 5,000 square metres, the British Pavilion sat on a 6,000 square metres lot, as did the Canadian Pavilion. The flagship Chinese National Pavilion had 20,000 square metres of exhibition space.).
answer:

How many hectares was the largest World Expo?
