Given the task definition, example input & output, solve the new input case.
Generate an explanation for the given claim using the provided supporting material from the paragraph. Please consider the following points while generating an output. 1) The claim will always have supporting proof in the paragraph, and the paragraph will have a clear point of view supporting the claim. 2) There can be instances where direct correlation to the claim is not available. Make use of the sentences in the paragraph to provide a corresponding output supporting the claim. 3) The explanation should be at least one and at most twelve sentences long.
Example: Paragraph: "Although the story didn't cite the cost of appendectomy emergency or urgent surgery and we wish it had, we nonetheless will give it a satisfactory score because it at least cited what the editorial writer wrote, ""A secondary benefit is the savings to the hospital generated by minimizing staff and anesthesiologist presence late in the evening and during the wee hours of the morning."" As with our harms score above, although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Despite running less than 300 words, this story did an adequate job in explaining the quality of the evidence, including pointing out limitations. No disease-mongering here. The story meets the bare minimum requirement for this criterion in that it at least cited what an editorial stated. The focus of the story was on a study comparing emergency appendectomy with surgery done up to 12 hours later or beyond. This is the whole focus of the story and one we applaud when it begins: ""Appendectomy is the most common emergency surgery in the world, but it doesn't have to be."" There were no claims made about the novelty of this research, and we may have wished for a bit more context on this. Nonetheless, the potential for guiding future care decisions was made clear. Not applicable. Given that the story only pulled excerpts from the journal article and the accompanying editorial, and didn't include any fresh quotes from interviews, we can't be sure of the extent to which it may have been influenced by a news release.". Claim: Some appendicitis cases may not require 'emergency' surgery
Output: We really don't understand why only a handful of mainstream news organizations reported this story. (At least in what we found.) The most common emergency surgery in the world. Rushing to emergency surgery may not carry any benefit. Waiting a few hours may be safer and less expensive. Why is that not a story? We applaud USA Today for finding time and space and clearly it didn't need to free up much space to do a good job telling the story. The story explains that as many as 300,0 appendectomies are done each year in the US. That figure alone explains why this is an important study to report.
The output is an analysis of the claim while considering the paragraph as a reference. The output highlights the key features presented in the paragraph and explains the claim accordingly.

New input case for you: Paragraph: Big advances in the battles against infectious diseases such as measles, malaria, tuberculosis and polio have continued to extend life expectancy although other factors, such as people's lifestyles, are constraining longevity, the WHO said in its annual statistics report. The longest life expectancy at birth is for baby girls in Japan, at 87.0 years, and boys in Iceland, at 81.2 years. Japan, Switzerland, Singapore, Italy and Luxembourg rank in the top 10 for both sexes. "There are major gains in life expectancy in recent decades and they continue," said Ties Boerma, chief of statistics and information systems at the WHO. The lowest life expectancy is in sub-Saharan Africa, where nine countries have expectancy of less than 55 for babies of both sexes. Lifestyle changes leading to heart problems and other diseases were curbing life expectancy in some cases. "We're seeing a health transition from success in infectious diseases to more people dying, including at younger ages, from non-communicable diseases," said Boerma. However, even in the rich countries where people live longest, there is no sign of life expectancy gains slowing down. "If human life expectancy was capped at population level at around 90 years of life we would expect to see a slowdown as we approach those limits. We're not seeing that," said Colin Mathers, coordinator of WHO's statistics on mortality. For the first time the annual statistics report, the most comprehensive statistical overview of the world's health, measured "years of life lost", a number that takes account of the age when people die as well as the number of deaths, to put more focus on the things that kill more people at a younger age. Years of life lost to diarrhea and respiratory infections, the biggest causes of early deaths in 2000, had fallen by 40 percent and 30 percent respectively by 2012, when ischemic heart disease was the biggest factor in early deaths. Years of life lost to road injuries have also increased by 14 percent between 2000 and 2012 as more people driving in developing countries outweighed gains in road safety elsewhere. Life expectancy at birth has increased in almost every country since 1990, and in almost all cases it was higher in 2012 than in 2011, with Botswana, Cote d'Ivoire and Syria among the exceptions. Another was Pakistan, where life expectancy averaged 65 years in 2012, down from 67 years in last year's report. Mathers said that reduction reflected improved data, which revealed child mortality was 30 percent higher than previously thought. The global average life expectancy for a 60-year-old has also increased, with hope of another 20 years in 2012 instead of 18 years in 1990. But not everywhere. In Russia and several other former Soviet states, life expectancy for a 60-year-old was lower in 2012 than in 1990. Mathers said death rates rose fast in the early 1990s, due to cardiovascular disease and injury, both influenced by high rates of binge drinking. Although the death rates have since improved, they have not yet dropped to pre-1990 levels. Russia's experience surprised epidemiologists who had expected chronic diseases would take a long time to take root. Many countries, especially those recovering from conflict, have also shown that it is possible to make big gains fast. "We've seen in many countries a catch-up, really fast progress," said Boerma. "Examples - Liberia, which has been our fastest catch-up country, but also Rwanda, Cambodia. So if they come out of a crisis with good leadership, there's enormous progress in health." Claim: Global life expectancy rises again, but new challenges loom.
Output:
Average life expectancy has risen globally to 73 years for a girl born in 2012 and 68 for a boy following successes in fighting diseases and child mortality, the World Health Organization said on Thursday.
