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

Passage: The Panthers came into the game hoping to avenge their loss to the Saints two weeks prior, with the winner taking first place in the NFC South. In the second quarter, a strong rain blanketed the stadium, reminiscent of a similar storm in 2011 against Jacksonville. New Orleans scored late to go up 13-10 with under 2 minutes to play. Cam Newton led the offense down the field and into the red zone on the following possession. With under a minute to play, Newton threw the game-winning touchdown pass to receiver Domenik Hixon, who was replacing an injured Steve Smith. It was later reported the stadium's press box shook when Hixon caught the touchdown. Carolina's defense was able to prevent the Saints from completing a last-second Hail Mary. With the win, the Panthers clinched a playoff spot and improved to 11-4. The team also improved to 9-18 when Newton turns the ball over.
How many games had the Panthers won before this game?

Passage: In September 1913 in Göttingen, Weyl married Friederike Bertha Helene Joseph (March 30, 1893 - September 5, 1948) who went by the name Helene (nickname "Hella"). Helene was a daughter of Dr. Bruno Joseph (December 13, 1861 - June 10, 1934), a physician who held the position of Sanitätsrat in Ribnitz-Damgarten, Germany. Helene was a philosopher (she was a disciple of phenomenologist Edmund Husserl) and also a translator of Spanish literature into German and English (especially the works of Spanish philosopher José Ortega y Gasset).  It was through Helenes close connection with Husserl that Hermann became familiar with (and greatly influenced by) Husserls thought. Hermann and Helene had two sons, Fritz Joachim Weyl (February 19, 1915 - July 20, 1977) and Michael Weyl (September 15, 1917 - March 19, 2011), both of whom were born in Zürich, Switzerland. Helene died in Princeton, New Jersey on September 5, 1948. A memorial service in her honor was held in Princeton on September 9, 1948. Speakers at her memorial service included her son Fritz Joachim Weyl and mathematicians Oswald Veblen and Richard Courant. In 1950 Hermann married sculptress Ellen Bär (née Lohnstein) (April 17, 1902 - July 14, 1988), who was the widow of professor Richard Josef Bär (September 11, 1892 - December 15, 1940) of Zürich.

How many years after Friederike Bertha Helene Joseph's father died did she?
