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.

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

Passage: The Browns hosted the rival Pittsburgh Steelers on a night with subzero wind chills for a Week 14 duel. In windy conditions, Phil Dawson hit a pair of 29-yard field goals, and Chris Jennings had a 10-yard touchdown run to put the Browns up 13. Jeff Reed nailed a field goal before the half to draw the Steelers within 10, and hit another in the third to bring them within a touchdown. However, a scoreless fourth by both teams led the Browns to their first win against the Steelers since 2003, and the Browns became only the fourth team in NFL history to be at least 10 games under .500 and defeat the defending Super Bowl champions. With the win, the Browns improved to 2-11, snapped a twelve-game losing streak against the Steelers and won against them for the first time since 2003 when they defeated the team 33-13 in Pittsburgh.  The team also won their first home game since an October 2008 victory, interestingly against then-defending Super Bowl champion New York Giants. KR Josh Cribbs was named AFC Special Teams Player of the Week.
How many field goals were made in the game?

Passage: The Russians and the Japanese both contributed troops to the eight-member international force sent in 1900 to quell the Boxer Rebellion and to relieve the international legations under siege in the Chinese capital, Beijing. Russia had already sent 177,000 soldiers to Manchuria, nominally to protect its railways under construction. The troops of the Qing Empire and the participants of the Boxer Rebellion could do nothing against such a massive army and were ejected from Manchuria. After the Boxer Rebellion, 100,000 Russian soldiers were stationed in Manchuria. The Russian troops settled in and despite assurances they would vacate the area after the crisis, by 1903 the Russians had not established a timetable for withdrawal and had actually strengthened their position in Manchuria.

How many fewer Russian soldiers remained in Manchuria after the Rebellion as originally were sent?
