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.

Question: Passage: The 5 October 1910 revolution was the overthrow of the centuries-old Portuguese Monarchy and its replacement by the Portuguese Republic. It was the result of a coup d'état organized by the Portuguese Republican Party. By 1910, the Kingdom of Portugal was in deep crisis: British pressure on Portugal's colonies, the royal family's expenses, the assassination of the King and his heir in 1908, changing religious and social views, instability of the two political parties , the dictatorship of João Franco, and the regime's apparent inability to adapt to modern times all led to widespread resentment against the Monarchy. The proponents of the republic, particularly the Republican Party, found ways to take advantage of the situation. The Republican Party presented itself as the only one that had a programme that was capable of returning to the country its lost status and place Portugal on the way of progress. After a reluctance of the military to combat the nearly two thousand soldiers and sailors that rebelled between 3 and 4 October 1910, the Republic was proclaimed at 9 o'clock of the next day from the balcony of the Paços do Concelho in Lisbon. After the revolution, a provisional government led by Teófilo Braga directed the fate of the country until the approval of the Constitution in 1911 that marked the beginning of the First Republic. Among other things, with the establishment of the republic, national symbols were changed: the national anthem and the flag. The revolution produced some civil and religious liberties, although there was no advance in women's rights and in workers rights, unlike what happened in other European countries.

Answer: How many national symbols were changed with the beginning of the First Republic?


Question: 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.

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


Question: Passage: Following the Mamluk victory over the Mongols in 1260 at the Battle of Ain Jalut by Qutuz and his general Baibars, Qutuz was assassinated, leaving Baibars to claim the sultanate for himself. As Sultan, Baibars proceeded to attack the Christian crusaders at Arsuf, Athlith, Haifa, Safad, Jaffa, Ascalon, and Caesarea. As the Crusader fortress cities fell one by one, the Christians sought help from Europe, but assistance was slow in coming. In 1268 Baibars captured Antioch, thereby destroying the last remnant of the Principality of Antioch, securing the Mamluk northern front and threatening the small Crusader County of Tripoli. Louis IX of France, having already organized a large crusader army with the intent of attacking Egypt, was diverted instead to Tunis, where Louis himself died in 1270. Prince Edward of England arrived in Tunis too late to contribute to the remainder of the crusade in Tunis. Instead, he continued on his way to the Holy Land to assist Bohemund VI, Prince of Antioch and Count of Tripoli, against the Mamluk threat to Tripoli and the remnant of the Kingdom of Jerusalem. On May 9, 1271, Edward finally arrived at Acre. He brought a small but not insignificant contingent of no more than 1,000 men, including 225 knights.

Answer:
At how many locations did Baibars attack the Christian crusaders?
