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.

[EX Q]: Passage: New Caledonia is a major source for nickel and contains roughly 10% of the worlds known nickel supply. The islands contain about 7,100,000 tonnes of nickel. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the Nickel mining in New Caledonia after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000). In recent years, the economy has suffered because of depressed international demand for nickel, due to the ongoing financial crisis of 2007–2008. Only a negligible amount of the land is suitable for cultivation, and food accounts for about 20% of imports. In addition to nickel, the substantial financial support from France and tourism are keys to the health of the economy. In the 2000s, large additions were made to nickel mining capacity. The Goro, New Caledonia is expected to be one of the largest nickel producing plants on Earth. When full-scale production begins in 2013 this plant will produce an estimated 20% of the global nickel supply. However, the need to respond to environmental concerns over the countrys globally recognized ecological heritage, may increasingly need to be factored into capitalization of mining operations.

[EX Q]: Passage: With Steigerwalds departure in 1999, Mike Lange shared the broadcast booth with former Penguins defenseman Peter Taglianetti. Taglianetti, a two-time Stanley Cup winner with the team in 1991 and 1992, remained in the position for one season before being replaced by Ed Olczyk. Lange and Olczyk were broadcast partners from 2000 until 2003, when Olczyk left the booth to become the 18th head coach in Penguins history that had become upon due to the firing of previous Head Coach Rick Kehoe after the 2002–03 season. With Olczyks vacancy, the Penguins hired Bob Errey as their new color commentator for the start of the 2003–04 season (a position that he continues to hold as of the start of the 2012–13 season. Lange and Errey remained in the booth until 2005–06. After 26 seasons in the television broadcast booth, Mike Lange was not retained by FSN Pittsburgh. Instead, he was replaced by former broadcast partner Paul Steigerwald, who remained the TV play-by-play broadcaster for the team until the 2016–17 season. Lange returned to the radio broadcast booth and currently holds the position of radio play-by-play announcer, the same position he had held with the team in the mid-1970s. Following the 2016–17 season, Steigerwald moved back to the Penguins front office and NHL Network (U.S. TV network) personality Steve Mears was hired as the new television play-by-play announcer starting with the 2017–18 season.

[EX Q]: Passage: The Dolphins opened the regular season in the annual Thursday NFL Kickoff Game against the Pittsburgh Steelers on September 7.  Even though newly acquired QB Daunte Culpepper was doing a pretty good job on the pass and RB Ronnie Brown provided a touchdown, the Dolphins trailed 14-10 going into the second half, until Brown got another rushing touchdown.  Unfortunately, an 87-yard touchdown pass to Steeler tight end Heath Miller and a 42-yard interception return by ROLB Joey Porter sealed the Dolphins' fate. Head coach Nick Saban attempted to challenge Miller's touchdown reception on the grounds that he stepped out of bounds before reaching the goal line (which television replays proved was correct), however, officials failed to see Saban throw the red flag before the Steelers kicked the extra point, and the Dolphins were unable to challenge the call. Of more concern than simply the loss was the performance of the Dolphins' prized offseason acquisition. Daunte Culpepper threw two interceptions, and floated several passes that were almost intercepted. This performance has sparked debate as to whether he will be able to return to his 2004 form or if he will have a repeat of his terrible 2005 campaign. One positive from the game was slot WR Wes Welker. He had 67 yards receiving and set up the first TD for Miami.
