TASK DEFINITION: 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.
PROBLEM: Passage: In the 1840s Nicholas I of Russia reduced 64,000 szlachta to commoner status. Despite this, 62.8% of Russias nobles were szlachta in 1858 and still 46.1% in 1897. Serfdom was abolished in Russian Poland on February 19, 1864. It was deliberately enacted in a way that would ruin the szlachta. It was the only area where peasants paid the market price in redemption for the land (the average for the empire was 34% above the market price). All land taken from Polish peasants since 1846 was to be returned without redemption payments. The ex-serfs could only sell land to other peasants, not szlachta. 90% of the ex-serfs in the empire who actually gained land after 1861 were in the 8 western provinces. Along with Romania, Polish landless or domestic serfs were the only ones to be given land after serfdom was abolished. All this was to punish the szlachtas role in the uprisings of 1830 and 1863. By 1864 80% of szlachta were déclassé (downward social mobility),  petty nobles were worse off than the average serf, 48.9% of land in Russian Poland was in peasant hands, nobles still held 46%. In the Second Polish Republic the privileges of the nobility were lawfully abolished by the March Constitution (Poland) in 1921 and as such not granted by any future Poland law.

SOLUTION: By how many percent did szlachtas decrease from 1858 to 1897?

PROBLEM: Passage: On 28 April 1724, the city of Emden called on its possession Oldersum to prepare for war and arm themselves. On 2 February 1726, troops from Emden fought a battle in Leer against the princely troops. The latter were victorious. Soon afterwards, the renitent faction was condemned in an imperial decree. The conflict, however, continued and on 7 April 1726, another battle was fought in the streets of Leer, killing and wounding many soldiers. In April 1727, the Prince called in reinforcements from Denmark. A group of 60 men from Oldersum united with troops from Emden and other localities in the Emden area and marched to Norden, where they lost another battle against the Prince's army. Another imperial decree again condemned the renitent faction and ordern them to pay reparations. The Prince took over the administration of Oldersum from the city of Emden, and imperial troops occupied the castle at Oldersum. When the conflict ended, the Prince emerged victoriously and the recalcitrant city of Emden had to submit to him. However, the Prince had won a Pyrrhic victory.

SOLUTION: How many battles did Emden fight against the Prince's army?

PROBLEM: Passage: Hoping to rebound from their miserable road loss to the Jets, the Cardinals went home for a Week 5 interconference duel with the Buffalo Bills. In the first quarter, the Cardinals took flight as QB Kurt Warner completed a two-yard TD pass to WR Larry Fitzgerald. In the second quarter, Arizona increased its lead with rookie RB Tim Hightower getting a 17-yard TD run. The Bills responded with QB J. P. Losman completing an 87-yard TD pass to WR Lee Evans, yet the Cardinals answered right back with RB Edgerrin James getting a one-yard TD run. Buffalo would answer with Losman getting a two-yard TD run, yet the Cardinals continued its momentum with kicker Neil Rackers getting a 47-yard field goal. In the third quarter, the Bills tried to come back as kicker Rian Lindell got a 48-yard field goal, but Arizona kept its intensity up as Warner completed a two-yard TD pass to Fitzgerald. In the fourth quarter, the Cardinals pulled away as Rackers nailed a 38-yard field goal, along with Hightower getting a two-yard TD run.

SOLUTION:
How long was Rackers final field goal?
