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.

Q: Passage: The Jets got the ball first and Pennington led the Jets on a 16-play, 83-yard drive that took 8:30 off the clock before Mike Nugent kicked a 27-yard field goal. On the Browns' next possession, Reuben Droughns had two big gains to put the Browns in position for Phil Dawson's 47-yard field goal, knotting the score, 3-3. Pennington was then intercepted by Sean Jones, and Charlie Frye led the Browns on a long drive that was capped by a 2-yard touchdown run by Droughns. Frye would get intercepted by Eric Smith on the Browns' next possession, but Nugent missed a 52-yard field goal wide right, his first missed field goal since Week 1. However, the Jets would get a break as Dawson missed a chip-shot 26-yard field goal at the end of the first half. Still, Cleveland led 10-3 at halftime. Cleveland got the ball first in the second half, and Droughns continued to move the ball, picking up solid yardage before Frye found Kellen Winslow II open on a 30-yard touchdown reception. After the teams traded punts, Leon Washington fumbled on the Jets' 10-yard line, with Nick Eason forcing and Kamerion Wimbley recovering. Dawson knocked in a 21-yard field goal to give Cleveland a 20-3 lead with 3:51 left in the third quarter. The Jets got an immediate lift when Justin Miller returned the ensuing kickoff 99 yards for a score, his second return of the year, to cut the lead to ten. After a Browns punt, Pennington drove the Jets into position for Nugent's 47-yard field goal to narrow the deficit to 20-13. But on the Jets' next possession, Pennington was again intercepted by Jones, but Cleveland was forced to punt. After another trade of punts, the Jets took over on Cleveland's 47-yard line with 1:56 to play. On 4th-and-4 from the Cleveland 24 with 1:06 to play, Pennington lofted a pass that Chris Baker leapt for and caught with one hand as he began to land. Just before his foot hit the ground, the Browns' Brodney Pool levelled Baker, who landed out-of-bounds but still in possession of the ball. The referee ruled that Baker was out-of-bounds, rather than ruling he was forced out, which would have led to a touchdown. Eric Mangini called a timeout in the hopes that the referees would review the play, but since it was a judgement call, it was non-reviewable under NFL rules. Frye took a knee to end the game.

A: How many field goal attempts were missed in the game?

Q: Passage: Trying to end a three-game skid, the 49ers flew to Qwest Field for an NFC West rematch with the Seattle Seahawks on Thursday night.  In the first quarter, the Niners started off bumpy as Seahawks RB Shaun Alexander got a 3-yard TD run for Seattle's early strike and the only score of the period.  In the second quarter, San Francisco would get a field goal before halftime as kicker Joe Nedney nailed one from 39 yards out.  After a scorless third quarter, the Niners were in full force as QB Alex Smith completed an 8-yard TD pass to rookie TE Vernon Davis.  Afterwards, Smith would complete a 20-yard TD pass to RB Frank Gore.  Then, the 49ers wrapped the game up with Smith getting a very easy 18-yard QB sneak for a touchdown.  Seattle would get one more score as QB Matt Hasselbeck completed a 22-yard TD pass to TE Jerramy Stevens.  Fortunately, the Niners would get the win and the season sweep over the Seahawks.  With the win, the 49ers improved to 6-8.

A: How long was Frank Gore's touchdown?

Q: Passage: The East Asia/Pacific region has reached its goals on nutrition, in part due to the improvements contributed by China, the region’s most populous country. China has reduced its underweight prevalence from 19 percent to 8 percent between 1990 and 2002. China played the largest role in the world in decreasing the rate of children under five underweight between 1990 and 2004, halving the prevalence. This reduction of underweight prevalence has aided in the lowering of the under 5 mortality rate from 49 to 31 of 1000. They also have a low birthweight rate at 4%, a rate comparable to industrialized countries, and over 90% of households receive adequate iodized salts. However, large disparities exist between children in rural and urban areas, where 5 provinces in China leave 1.5 million children iodine deficient and susceptible to diseases. Singapore, Vietnam, Malaysia, and Indonesia are all projected to reach nutrition MDGs. Singapore has the lowest under five mortality rate of any nation, besides Iceland, in the world, at 3%. Cambodia has the highest rate of child mortality in the region (141 per 1,000 live births), while still its proportion of underweight children increased by 5 percent to 45% in 2000. Further nutrient indicators show that only 12 per cent of Cambodian babies are exclusively breastfed and only 14 per cent of households consume iodized salt.

A:
By how many percent did China's underweight prevalence decrease from 1990 to 2002?
