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: Superferry 14 was a large ferry destroyed by a bomb on 27 February 2004, killing 116 people in the Philippines' worst terrorist attack and the world's deadliest terrorist attack at sea. On that day, the 10,192 ton ferry sailed out of Manila with about 900 passengers and crew on board. A television set filled with 8 lb.  of TNT had been placed on board. 90 minutes out of port, the bomb exploded. 63 people were killed instantly and 53 were missing and presumed dead. Despite claims from terrorist groups, the blast was initially thought to have been an accident caused by a gas explosion. However, after divers righted the ferry five months after it had sunk, they found evidence of a bomb blast. A man called Redendo Cain Dellosa admitted to planting the bomb for Abu Sayyaf. Six suspects were arrested in connection with the bombing while the masterminds, Khadaffy Janjalani and Abu Sulaiman, were killed.
[EX A]: How many days did the worst terrorist attack and the world's deadliest terrorist attack at sea overlap?

[EX Q]: Passage: The February Revolution , known in Soviet historiography as the February Bourgeois Democratic Revolution, was the first of two revolutions which took place in Russia in 1917. The main events of the revolution took place in and near Petrograd , the then-capital of Russia, where longstanding discontent with the monarchy erupted into mass protests against food rationing on 23 February Old Style . Revolutionary activity lasted about eight days, involving mass demonstrations and violent armed clashes with police and gendarmes, the last loyal forces of the Russian monarchy. On 27 February O.S.  mutinous Russian Army forces sided with the revolutionaries. Three days later the Czar Nicholas II abdicated, ending Romanov dynastic rule and the Russian Empire. A Russian Provisional Government under Prince Georgy Lvov replaced the Russian Council of Ministers. The revolution appeared to break out without any real leadership or formal planning. Russia had been suffering from a number of economic and social problems, which compounded after the start of World War I in 1914. Disaffected soldiers from the city's garrison joined bread rioters, primarily women in bread lines, and industrial strikers on the streets. As more and more troops deserted, and with loyal troops away at the Front, the city fell into chaos, leading to the overthrow of the Czar. In all, over 1,300 people were killed during the protests of February 1917.
