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: Mount Vesuvius has erupted many times. The famous eruption in AD 79 was preceded by numerous others in prehistory, including at least three significantly larger ones, the best known being the Avellino eruption around 1800 BC which engulfed several Bronze Age settlements. Since AD 79, the volcano has also erupted repeatedly, in 172, 203, 222, possibly in 303, 379, 472, 512, 536, 685, 787, around 860, around 900, 968, 991, 999, 1006, 1037, 1049, around 1073, 1139, 1150, and there may have been eruptions in 1270, 1347, and 1500. The volcano erupted again in 1631, six times in the 18th century (including 1779 and 1794), eight times in the 19th century (notably in 1872), and in 1906, 1929 and 1944. There have been no eruptions since 1944, and none of the eruptions after AD 79 were as large or destructive as the Pompeian one. Vesuvius entered a new phase in December 1631, when a major eruption buried many villages under lava flows, killing around 3,000 people. Torrents of lahar were also created, adding to the devastation. Activity thereafter became almost continuous, with relatively severe eruptions occurring in 1660, 1682, 1694, 1698, 1707, 1737, 1760, 1767, 1779, 1794, 1822, 1834, 1839, 1850, 1855, 1861, 1868, 1872, 1906, 1926, 1929, and 1944.
[EX A]: Did Mount Vesuvius erupt more times in the 18th or 19th centuries?

[EX Q]: Passage: High gasoline prices in the US, approaching  a gallon by March 2012, contributed to record monthly sales of the Prius family vehicles. A total of 28,711 units were sold in the United States during March 2012, becoming the one-month record for Prius sales ever. The third-generation Prius liftback accounted for 18,008 units (62.7%); the Prius v accounted for 4,937 units (17.2%); the Prius c, for 4,875 units (17.0%); and the Prius Plug-in Hybrid, for 891 units (3.1%). Another record was set during the first-quarter of 2012, with Prius family sales of 60,859 units, it became the best selling quarter ever. Sales of Toyota Prius family vehicles in California represented 26% of all Prius purchases in the US during 2012. With 60,688 units sold during this year, the Prius became the best selling vehicle in California, ahead of the previous leader, the Honda Civic (57,124 units) and the third ranked, the Toyota Camry (50,250 units). The Prius nameplate was again in 2013 the best selling vehicle in California with 69,728 units sold in the state, ahead of the Honda Civic (66,982) and the Honda Accord (63,194).
[EX A]:
How many percent of the vehicles were not third generation Prius liftback?
