This task involves creating answers to complex questions, from a given passage. Answering these questions, typically involve understanding multiple sentences. Make sure that your answer has the same type as the "answer type" mentioned in input. The provided "answer type" can be of any of the following types: "span", "date", "number". A "span" answer is a continuous phrase taken directly from the passage or question. You can directly copy-paste the text from the passage or the question for span type answers. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words. A "number" type answer can include a digit specifying an actual value. For "date" type answers, use DD MM YYYY format e.g. 11 Jan 1992. If full date is not available in the passage you can write partial date such as 1992 or Jan 1992. If you find multiple spans, please add them all as a comma separated list. Please restrict each span to five words.

[EX Q]: Passage: In the 1850s, the infant mortality rate in the United States was estimated at 216.8 per 1,000 babies born for whites and 340.0 per 1,000 for African Americans, but rates have significantly declined in the West in modern times. This declining rate has been mainly due to modern improvements in basic health care, technology, and medical advances. In the last century, the infant mortality rate has decreased by 93%. Overall, the rates have decreased drastically from 20 deaths in 1970 to 6.9 deaths in 2003 (per every 1000 live births). In 2003, the leading causes of infant mortality in the United States were congenital anomalies, disorders related to immaturity, SIDS, and maternal complications. Babies born with low birth weight increased to 8.1% while cigarette smoking during pregnancy declined to 10.2%. This reflected the amount of low birth weights concluding that 12.4% of births from smokers were low birth weights compared with 7.7% of such births from non-smokers. According to the New York Times, "the main reason for the high rate is preterm delivery, and there was a 10% increase in such births from 2000 to 2006."  Between 2007 and 2011, however, the preterm birth rate has decreased every year.  In 2011 there was a 11.73% rate of babies born before the 37th week of gestation, down from a high of 12.80% in 2006. 
Question: How many fewer babies died per 1000 in 2003 than in 1970? 
Answer type: Number 
[EX A]: 13.1.

[EX Q]: Passage: The minimum wage, public-sector wages, and old-age pensions are routinely raised twice a year to ensure that base income is not eroded by inflation. Although no statistics are published on average wages in Uzbekistan, pensions as a proxy for the average wage increased significantly between 1995 and 2006, both in real terms and in U.S. dollars. The monthly old-age pension increased in real (CPI-adjusted) sums by almost a factor of 5 between 1995 and 2006. The monthly pension in U.S. dollars was around $20–$25 until 2000, then dropped to $15–$20 between 2001 and 2004, and now is $64. The minimum wage was raised to $34.31 in November 2011. Assuming that the average wages in the country are at a level of 3-4 times the monthly pension, we estimate the wages in 2006 at $100–$250 per month, or $3–$8 per day. 
Question: How many years did it take for pensions to increase by a factor of almost 5? 
Answer type: Number 
[EX A]: 11.
