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: Richard Gabriel estimated that roughly 2,400 PLO fighters were killed during the war, of whom about 1,400 were killed throughout southern Lebanon and another 1,000 killed during the Siege of Beirut. Gabriel also estimated that between 5,000 and 8,000 civilians died during the war. Some later estimates have put the total figure at 18-19,000 killed and more than 30,000 wounded, most of them civilians. 80% of villages in South Lebanon were damaged, with some completely destroyed. The Israeli government maintained that about 1,000 Palestinian fighters and 800 Lebanese civilians died during the invasion, excluding the siege of Beirut. Kenneth Pollack estimated that 1,200 Syrian soldiers were killed and about 3,000 wounded during the war.
[EX A]: How many more PLO fighters were killed throughout southern Lebanon than during the Siege of Beirut?

[EX Q]: Passage: The first German battlecruiser——was commenced March 1908. Four Parsons turbines were used, improving speed to 27 knots and reducing weight. Four twin turrets mounted 28 cm guns; although the two centre turrets were still placed one either side of the ship, they were offset so could now fire either side. The design was considered a success, but the cost at 35.5 million marks was significantly above the 1906 allocation. Light cruiser development continued with the  light cruisers, which were to become famous for their actions in the start of World War I in the Pacific. The ships were 3,300 tons, and armed with ten 10.5 cm rapid fire guns and a speed around 24 knots.  cost 7.5 million marks, and  6 million marks. Four  were produced between 1907 and 1911 at 4,400 tons and around 8 million marks each. These had turbines, twelve 10.5 cm guns as main armament, but were also equipped to carry and lay 100 mines. From 1907 onward, all torpedo boats were constructed using turbine engines.
[EX A]: How many knots faster could the battlecruiser travel than the light cruisers?

[EX Q]: Passage: King Ottokar II of Bohemia improved fortifications and rebuilt the royal palace for the purposes of representation and housing. In the 14th century, under the reign of Charles IV the royal palace was rebuilt in Gothic style and the castle fortifications were strengthened. In place of rotunda and basilica of St. Vitus began building of a vast Gothic church, that were completed almost six centuries later. During the Hussite Wars and the following decades, the castle was not inhabited. In 1485, King Ladislaus II Jagello began to rebuild the castle. The massive Vladislav Hall  was added to the Royal Palace. New defence towers were also built on the north side of the castle. A large fire in 1541 destroyed large parts of the castle. Under the Habsburgs, some new buildings in Renaissance style were added. Ferdinand I built the Belvedere as a summer palace for his wife Anne. Rudolph II used Prague Castle as his main residence. He founded the northern wing of the palace, with the Spanish Hall, where his precious art collections were exhibited. The Second Defenestration of Prague in 1618 took place at the castle and began the Bohemian Revolt. During the subsequent wars, the Castle was damaged and dilapidated. Many works from  the collection of Rudolph II were looted by Swedes in 1648, in the Battle of Prague  which was the final act of the Thirty Years' War. The last major rebuilding of the castle was carried out by Empress Maria Theresa in the second half of the 18th century. Following his abdication in 1848, and the succession of his nephew, Franz Joseph, to the throne, the former emperor, Ferdinand I, made Prague Castle his home.
[EX A]:
A fire destroyed part of what castle?
