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: With Steigerwalds departure in 1999, Mike Lange shared the broadcast booth with former Penguins defenseman Peter Taglianetti. Taglianetti, a two-time Stanley Cup winner with the team in 1991 and 1992, remained in the position for one season before being replaced by Ed Olczyk. Lange and Olczyk were broadcast partners from 2000 until 2003, when Olczyk left the booth to become the 18th head coach in Penguins history that had become upon due to the firing of previous Head Coach Rick Kehoe after the 2002–03 season. With Olczyks vacancy, the Penguins hired Bob Errey as their new color commentator for the start of the 2003–04 season (a position that he continues to hold as of the start of the 2012–13 season. Lange and Errey remained in the booth until 2005–06. After 26 seasons in the television broadcast booth, Mike Lange was not retained by FSN Pittsburgh. Instead, he was replaced by former broadcast partner Paul Steigerwald, who remained the TV play-by-play broadcaster for the team until the 2016–17 season. Lange returned to the radio broadcast booth and currently holds the position of radio play-by-play announcer, the same position he had held with the team in the mid-1970s. Following the 2016–17 season, Steigerwald moved back to the Penguins front office and NHL Network (U.S. TV network) personality Steve Mears was hired as the new television play-by-play announcer starting with the 2017–18 season.
How many year was Lange and Olczyk broadcast partners?

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: Industry, especially the manufacturing sector, historically was linked to agricultural processing until the 1970s, when the construction of hydroelectric plants and new industrial incentives began to broaden the industrial base. Industry was composed principally of manufacturing and construction. Paraguay had no real mining sector, but the manufacture of construction materials included limited mining activity. Manufacturing and construction in the economy in the late 1980s remained dependent on developments in other sectors, such as agriculture and energy, for their growth. Although industry was becoming more visible in Paraguay in the 1980s, industry's share of GDP actually declined in the 1970s and 1980s because of more rapid growth in agriculture.

When did the industry's share of GDP start to decline?
