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 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.

Ex Output:
How many days did it take S-26 to get from San Diego to Pearl Harbor?


Ex Input:
Passage: This was the first Sunday Night Football game held in MetLife Stadium following a one-season absence. With the loss, the Giants fell to 3-8, and were mathematically eliminated from playoff contention after the Lions defeated the Bears on Thanksgiving four days later. This game, however, is best known for an acrobatic one-handed catch by Odell Beckham Jr. early in the 2nd quarter that would go down as one of the greatest catches in NFL history.  A penalty marker flew as he made the catch - for pass interference on Brandon Carr, who had been covering Beckham on that play.

Ex Output:
Which two teams played on Thanksgiving?


Ex Input:
Passage: As of 2014, IPv4 still carried more than 99% of worldwide Internet traffic. The Internet exchange in Amsterdam and Seattle are the only large exchanges that publicly show IPv6 traffic statistics, which as of October 2018 are tracking at about 2.9% and 7.7%, growing at about 1.9% and -2.6% per year, respectively. , the percentage of users reaching Google services with IPv6 reached 25.0% for the first time, growing at about 4.2% per year. This growth is down from 7.2% per year between July 2016 and July 2017.  about 27% of Alexa Top 1000 web servers support IPv6.

Ex Output:

How many years was growth down 7.2% in 2016 and 2017?
