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.

Question: Passage: After another series of shogunate victories on the outskirts of Osaka, the Summer Campaign came to a head at the battle of Tennōji. Hideyori planned a hammer-and-anvil operation, in which 55,000 men would attack the center of the Eastern Army, while a second force, 16,500 men led by Kyōgoku Tadataka, Ishikawa Tadafusa, and Kyōgoku Takatomo, would flank them from the rear. Another contingent waited in reserve. Ieyasu's army was led by his son, the Shogun Tokugawa Hidetada, and numbered around 155,000. They moved in four parallel lines, prepared to make flanking maneuvers of their own. Mistakes on both sides nearly ruined the battle, as Hideyori's ronin split off from the main group, and Hidetada's reserve force moved up without orders from the main force. In the end, however, Hideyori's commander Sanada Yukimura was killed, destroying the morale of the Western Army. The smaller force led directly by Hideyori sallied forth from Osaka Castle too late, and was chased right back into the castle by the advancing enemies; there was no time to set up a proper defense of the castle, and it was soon ablaze and pummeled by artillery fire. Hideyori committed seppuku, and the final major uprising against Tokugawa rule was put to an end, leaving the shogunate unchallenged for approximately 250 years. According to an account by an employee of the Dutch East India Company in Hirado, several daimyō set the castle on fire and attempted to defect to Ieyasu. Hideyori executed them by throwing them off the castle wall but could not extinguish the fire, causing his suicide. The account also stated that about 10,000 people died. History indicates that the legendary swordsman Miyamoto Musashi participated in the battle on the Toyotomi side, though he has no recorded accomplishments in this battle.

Answer: How many leaders led the second force to flank them from the rear?


Question: Passage: The Panthers' undefeated season came to an end with a 13-20 loss in Atlanta, dropping their record to 14-1. Carolina started off well with a Newton rushing TD, but Atlanta proved to be too much at home, culminating in a long touchdown pass from Falcons QB Matt Ryan to WR Julio Jones. The Falcons defense swarmed the field all day, as the Panthers couldn't manage a touchdown for the rest of the game. As a result, Atlanta pulled off the upset. Despite the loss, their only one of the regular season, Carolina kept both its playoff spot and division title.

Answer: How many points ahead were the falcons at the end of the game?


Question: Passage: Greece has suffered from recession, massive public debt, and poverty has increased. Those living in extreme poverty rose to 15% in 2015, up from 8.9% in 2011, and a huge increase from 2009 when it wasn’t more than 2.2%. Those people at risk for poverty or social exclusion was one in three or 35.7%. The rate among children 0-17 is 17.6% and for young people 18-29 the rate is 24.4%. With unemployment on the rise, those without jobs are at the highest risk at 70-75%, up from less than 50% in 2011. With jobs harder and harder to come by, a quarter of the population is out of work, and for people under 25 the rate is 50%. In some harder hit areas of western Greece, the younger generation unemployment rate is more than 60%. When people are out of work for more than two years, they lose their health insurance, further increasing the problems of those in poverty. When younger people are out of work, they rely on the older generations of their families to provide for them to get them through the hard times. However, long term unemployment across the country causes pension funds to decrease because they are getting less money from the working population, so those older generations are getting less money to provide for the younger generations and their entire families, putting more of them in poverty. Many aspects of the economic problems add to the problem. The Greeks people have continued job loss and wage cuts, as well as deep cuts in workers compensation and social welfare benefits. For those who are working, their wages have dropped. From 2008 to 2013, Greeks have become 40% poorer on average, and in 2014 saw their disposable household income drop below 2003 levels. The Economic Survey of Greece 2016 shows optimism in a stronger recovery in 2017 by using things like the reforms in place and outside investment in jobs to help change the course of the high levels of poverty.

Answer:
Across how many years did Greeks become 40% poorer?
