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: In week 16, the Lions flew back to Florida, this time to play the Miami Dolphins. The Lions took an early lead with a 39-yard field goal by Dave Rayner. The Dolphins tied it up with a 40-yard field goal by Dan Carpenter. In the second quarter, the Lions took the lead when Brandon Pettigrew caught a 20-yard touchdown pass. The Dolphins tied it up with a 4-yard rush by Lousaka Polite. Miami took the lead with a 13-yard TD catch by Davone Bess. After halftime, the Lions tied it back up with a 5-yard TD rush by Maurice Morris. The Dolphins responded with a 1-yard TD run by Ronnie Brown. Miami added to their lead with a 28-yard field goal. The Lions then scored 17 unanswered points. First Jahvid Best caught a 53-yard TD pass. Then Dave Rayner kicked a 47-yard field goal. They sealed their win when DeAndre Levy intercepted a Chad Henne pass and ran it back 30 yards for a touchdown. With the win not only did the Lions improve to 5-10, but it was their first back-to-back road victories since 2004, and first three-game winning streak since 2007.

Passage: Coming off their dominating home win over the Rams, the Jets flew to Gillette Stadium for a Week 11 AFC East rematch with the New England Patriots on Thursday Night Football.  In the first quarter, New York took flight as QB Brett Favre completed a 7-yard TD pass to RB Leon Washington.  The Patriots would respond with kicker Stephen Gostkowski getting a 42-yard field goal.  The Jets would increase their lead as kicker Jay Feely made a 22-yard field goal.  In the second quarter, New England would answer with Gostkowski making a 31-yard field goal, yet New York immediately replied as Washington returned the kickoff 92 yards for a touchdown.  Later, the Jets added onto their lead as Favre completed a 15-yard TD pass to WR Jerricho Cotchery to give the Jets a commanding 24-6 lead. The Patriots would get back into the game by closing out the half with a  QB Matt Cassel 19-yard TD pass to WR Jabar Gaffney. In the third quarter, New England hacked away at New York's lead as Cassel completed a 10-yard TD pass to TE Benjamin Watson (along with a 2-point conversion pass to Gaffney) on the final play of the 3rd quarter.  In the fourth quarter, the Patriots completely erased the Jets' 18-point lead with Gostkowski kicking a 47-yard field goal.  New York would answer with RB Thomas Jones getting a 1-yard TD run, but New England tied the game with Cassel completing a 16-yard TD pass to WR Randy Moss, who had beaten Ty Law as time expired.  In overtime,  the Jets took the kickoff and marched straight down the field to win on Feely's 34-yard field goal. The drive included some clutch throws by Favre, particularly a connection with Dustin Keller on 3rd-and-17 from deep in the Jets' zone. It was Favre's 42nd game-winning drive in the fourth quarter or overtime in his career. Washington was selected as AFC special teams player of the week for the first time in his career. His 92-yard touchdown was the fourth kick return TD of his career, surpassing Justin Miller for the club record.
