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.

Example Input: Passage: After the War of Independence and truce called in July 1921, representatives of the British government and the Irish treaty delegates, led by Arthur Griffith, Robert Barton and Michael Collins, negotiated the Anglo-Irish Treaty in London from 11 October to 6 December 1921. The Irish delegates set up headquarters at Hans Place in Knightsbridge, and it was here in private discussions that the decision was taken on 5 December to recommend the treaty to Dáil Éireann.The Second Dáil Éireann narrowly ratified the Treaty. In accordance with the treaty, on 6 December 1922 the entire island of Ireland became a self-governing Dominion called the Irish Free State . Under the Constitution of the Irish Free State, the Parliament of Northern Ireland had the option to leave the Irish Free State one month later and return to the United Kingdom. During the intervening period, the powers of the Parliament of the Irish Free State and Executive Council of the Irish Free State did not extend to Northern Ireland. Northern Ireland exercised its right under the treaty to leave the new Dominion and rejoined the United Kingdom on 8 December 1922. It did so by making an address to the King requesting, "that the powers of the Parliament and Government of the Irish Free State shall no longer extend to Northern Ireland." The Irish Free State was a constitutional monarchy sharing a monarch with the United Kingdom and other Dominions of the British Commonwealth. The country had a governor-general , a bicameral parliament, a cabinet called the "Executive Council", and a prime minister called the President of the Executive Council.
Example Output: According to the treaty, how many years after negotiation would the entire island of Ireland become a self-governing Dominion known as the Irish Free State?

Example Input: Passage: However, this was due to the influx of approximately 200,000 Crimean Tatars &ndash; a number equivalent to approximately 10% of Crimeas 1989 population – who arrived in Crimea after 1989 and whose population in that region increased by a factor of 6.4 from 38,000 to 243,400 between 1989 and 2001. Collectively, the net population loss in the regions of Ukraine outside the westernmost regions was 2,759,200 people or 6.6% of the 1989 population. The total population of these regions in 2001 was 39,186,100.
Example Output: How many Crimean Tatars did the population increase by between 1989 and 2001?

Example Input: Passage: Coming off their win over the Bears the Redskins flew to Ford Field for an NFC duel with the Lions. In the 2nd quarter the Redskins trailed early as QB Matthew Stafford got a 13-yard TD pass to WR Calvin Johnson. They pulled ahead with QB Donovan McNabb getting a 6-yard TD pass to RB Ryan Torain, followed by kicker Graham Gano making a 38 and a 46-yard field goal. The Redskins trailed slightly with Stafford getting a 2-yard TD pass to TE Brandon Pettigrew. The Redskins got the lead back with RB Keiland Williams getting a 5-yard TD run (With a failed 2-point conversion). The Lions replied with Stafford finding Johnson again on a 7-yard TD pass (With a failed 2-point conversion). After that, the Redskins took the lead again with WR Brandon Banks returning a kickoff 96 yards for a touchdown (With a failed 2-point conversion) to put the Redskins up 25-20. They soon fell behind with Stafford throwing a 10-yard TD pass to Johnson (With a successful 2-point conversion as Stafford passed to WR Bryant Johnson). This was followed by kicker Jason Hanson making a 32-yard field goal, and with DT Ndamukong Suh returning a fumble 17 yards to the endzone for a touchdown (With a failed 2-point conversion). With the loss, the Redskins went into their bye week at 4-4.
Example Output:
How many 2 point conversions were unsuccessful?
