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: The first German battlecruiserwas 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.
How many knots faster could the battlecruiser travel than the light cruisers?

Passage: Another 18-inning contest was played between the Atlanta Braves and the Houston Astros on October 9, 2005. In the 4th game of a 2005 National League Division Series at Minute Maid Park in Houston, Texas, the Braves (who were trailing the series two games to one and facing elimination) took a 6-1 lead into the 8th inning. A grand slam (baseball) by Lance Berkman in the bottom of the 8th brought the score to 6-5, and with two outs in the bottom of the 9th, Brad Ausmus homered to tie the game and send it to extra innings. The score remained deadlocked at 6-6 until the 18th, when the Astros Chris Burke (baseball) (who entered the game in the 9th inning as a pinch runner) homered to left field to win the game and send Houston to the 2005 National League Championship Series against the St. Louis Cardinals. Roger Clemens, who was brought in to pinch hitter in the 15th and pitched the last three innings in relief, was credited as the winning pitcher in the 5-hour, 50-minute contest. Adam LaRoche and Tim Hudson played in both 18-inning games. This one as Atlanta Braves and the other one as opposing sides of one another with Hudson pitching in both games as the visiting teams starting pitcher. It is the longest winner in a potential clinching game in baseball history.
How many innings was the game deadlocked for?
