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

[EX Q]: Passage: Taksin's first attempt at reunification—an expedition to Phitsanulok in May 1768—was unsuccessful. He captured Phimai at the end of 1768, and was crowned monarch in December 1768. By late 1769, he had defeated Nakhon Si Thammarat. In mid-1770, he finally defeated Phitsanulok, and became the sole ruler of Siam.
[EX A]: How many months after Taksin's first attempt at reunification was he crowned monarch?

According to the 2000 United States Census, 94.8 percent of the population aged 5 and older speak English at home. Spanish is the language most commonly spoken at home other than English. There were about 13,040 Spanish-language speakers in the state (1.4 percent of the population) in 2011. There were also 15,438 (1.7 percent of the state population) speakers of Indo-European languages other than English or Spanish, 10,154 (1.1 percent) speakers of a Native American language, and 4,052 (0.4 percent) speakers of an Asian or Pacific Islander language. Other languages spoken in Montana (as of 2013) include Assiniboine (about 150 speakers in the Montana and Canada), Blackfoot (about 100 speakers), Cheyenne (about 1,700 speakers), Plains Cree (about 100 speakers), Crow (about 3,000 speakers), Dakota (about 18,800 speakers in Minnesota, Montana, Nebraska, North Dakota, and South Dakota), German Hutterite (about 5,600 speakers), Gros Ventre (about 10 speakers), Kalispel-Pend dOreille (about 64 speakers), Kutenai (about 6 speakers), and Lakota (about 6,000 speakers in Minnesota, Montana, Nebraska, North Dakota, South Dakota). The United States Department of Education estimated in 2009 that 5,274 students in Montana spoke a language at home other than English. These included a Native American language (64 percent), German (4 percent), Spanish (3 percent), Russian (1 percent), and Chinese (less than 0.5 percent).
[EX A]:
How many more Indo-European than Native American speaker in Montana?
