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: Operating out of New London, Connecticut from 1923 to 1925, S-26 visited Saint Thomas, United States Virgin Islands and Trinidad from January to April 1924, and Hawaii from 27 April to 30 May 1925. Cruising from California ports, mainly Mare Island, California, San Diego, California, and San Pedro, California, S-26 visited Hawaii in the summers of 1927-1930. She also served in the Panama Canal area from March to May 1927, and in February 1929. Departing San Diego on 1 December 1930, she arrived at Pearl Harbor on 12 December. From then into 1938, S-26 served at Pearl Harbor. Sailing from there on 15 October 1938, she returned to New London on 25 March 1939. Entering a period of partial duty on 15 April that year, she resumed full duty on 1 July 1940.
Example Output: How many days did it take S-26 to get from San Diego to Pearl Harbor?

Example Input: Passage: On December 7, 2015, the Washington Post reported that since 2001, in five theaters of the war  that the total number of terrorists killed ranges from 65,800 to 88,600, with Obama administration being responsible for between 30,000 and 33,000.
Example Output: About how many terrorists (minimum) were killed by administrations before the Obama administration?

Example Input: Passage: Evangelical Christians comprised 52 percent of the states voters in 2008. A poll in 2005 showed that 53 percent of West Virginia voters are pro-life, the seventh highest in the country. A September 2011 Public Policy Polling survey found that 19% of West Virginia voters thought that same-sex marriage should be legal, while 71% thought it should be illegal and 10% were not sure. A separate question on the same survey found that 43% of West Virginia voters supported the legal recognition of same-sex couples, with 17% supporting same-sex marriage, 26% supporting civil unions but not marriage, 54% favoring no legal recognition and 3% not sure. A poll published regarding another social issue, abortion, in 2014 by Pew Research found that 35% of West Virginians supported legal abortion in "all or most cases" while 58% wanted it to be banned "in all or most cases." In 2008, 58 percent favored troop withdrawal from Iraq while just 32 percent wanted troops to remain. On fiscal policy in 2008, 52 percent said raising taxes on the wealthier individuals would benefit the economy, while 45 percent disagreed.
Example Output:
How many more percentage West Virginians voters banned abortion than supported in 2104?
