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: After winning over the Browns, the Steelers traveled further west to take on the Colts in a rematch of 2015's 45-10 blowout win. The Steelers struck first in the first quarter when Le'Veon Bell ran for a 5-yard touchdown to take a 7-0 lead. This would be followed by Ben Roethlisberger finding Antonio Brown on a 25-yard touchdown pass later on in the quarter to make it 14-0. The Colts got on the board in the second quarter when QB Scott Tolzien, starting in place of the injured Andrew Luck, found Donte Moncrief on a 5-yard touchdown pass to make it 14-7. However, the Steelers pulled away as Roethlisberger found Brown again this time on a 33-yard touchdown pass for a 21-7 lead at halftime. After a scoreless third quarter, the Steelers sealed the game with the only points in the second half when Roethlisberger found Brown again this time on a 22-yard touchdown pass and the eventual final score of 28-7. With the win, the Steelers improved to 6-5. Roethlisberger's record as a starter improved to 1-1 on Thanksgiving Day.
How many points did the Steelers have in the first quarter?

Passage: After their ouster from the coastal ports of China, Japanese and Portuguese traders collaborated with illegal smugglers on island ports along the Zhejiang and Fujian coast. Among these ports, Shuangyu on Liuheng Island  off the coast of Ningbo emerged as the primary emporium of clandestine trade. At first, Shuangyu only had temporary mat-sheds for the smugglers to house themselves and their goods during the trading season. In 1539, Fujianese traders started to guide foreign traders from Patani and Malacca to barter in Shuangyu and started to occupy the island. They were soon joined by the Fujianese merchants Jinzi Lao  and Li Guangtou , who led the Portuguese and assorted adventurers to Shuangyu. Attracted by the growing trade on the Zhejiang coast, the Xu brothers' syndicate moved their base of operations from the Malay Peninsula to Shuangyu. The existing clout of the Xu syndicate and its close partnership with the Portuguese made it the foremost smuggling bloc by 1542 after a series of mergers among the merchant-pirates in Shuangyu. The Ming navy began to clamp down on smuggling activities in 1543, but the Xu syndicate was able to repulse the Ming attacks in Shuangyu with the aid of Portuguese firepower. Hardened by their victories against the Ming navy, the smugglers expanded their network of activities down the coast of China all the way to Guangdong and inland to the metropolis of Nanjing, with Shuangyu being their hub. In 1544, this network was further expanded when Wang Zhi joined the Xu syndicate, bringing along his Japanese connections to Shuangyu. Thus Shuangyu reached its zenith as the biggest entrepôt in maritime East Asia trading goods from Europe and Asia until its downfall in 1548.
After the Ming navy began trying to stop smuggling in 1543, how many years passed before the Xu syndicate downfall?

Passage: During the Cold War, the Danish navy was rebuilt and modernised, with the main assignment being to repel an invasion from the Warsaw Pact. Typical operations requiring training were minelaying , 2,000 GRT), were the world's largest minelayers at their time - each had a complement of 280 900 kg mines) and sting attacks with small but fast combat craft , 158 GRT) and Willemoes-class missile torpedo boats , 260 GRT) and a self-sustaining mobile missile battery  equipped with targeting and guidance, capable of firing Harpoon missiles. The Danish intelligence capabilities were also expanded and the Danish submarines trained for very shallow water operations, while a special naval force - the Danish Frogman Corps was created. The naval bases in Frederikshavn and Korsør plus the fortresses at Langeland and Stevns were created through NATO funds in the 1950s. In case of war all Danish combat vessels were assigned to NATO's Allied Forces Baltic Approaches's naval command NAVBALTAP.

How many Danish naval bases were created with NATO funds in the 1950s?
