Given the task definition, example input & output, solve the new input case.
Given a paragraph, generate a claim that is supported by the given paragraph. 1) The claim must contain information from within the paragraph. 2) A sentence within the paragraph can be used as a claim. 3) The claim should not have contradictions within the paragraph. 4) The claim should be at most one sentence long.
Example: "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."
Output: Some appendicitis cases may not require 'emergency' surgery
The paragraph mentions that "Appendectomy is the most common emergency surgery in the world, but it doesn't have to be." which is considered evidence for the output. Thus, the output is a valid claim.

New input case for you: Scientists said on Monday an analysis of well-preserved ancient peach pits traces the domestication of this sweet fruit back at least 7,500 years to China's lower Yangtze River Valley in the vicinity of Shanghai. Indeed, peaches were among the first tree fruits to be domesticated as early human societies embraced horticulture, the study indicates. "There is a long history of peach cultivation in China," said one of the researchers, Yunfei Zheng of the Zhejiang Provincial Institute of Relics and Archaeology in Hangzhou, China, noting that China still leads the world in peach production. The researchers compared peach pits, also called stones, from six Chinese locations, covering a period of roughly 5,000 years. An analysis of pit size from each location showed that peaches were growing steadily larger as time passed in the Yangtze valley, illustrating that people there had been domesticating this fruit. It took perhaps 3,000 years before the domesticated peaches came to look like peaches grown now. Peach pits, almost indistinguishable from today's, date back about 4,300 to 5,300 years, the researchers said. Gary Crawford, a University of TorontoMississauga anthropology professor who took part in the study published in the journal PLOS ONE, said there were many reasons why the peach tree was a good candidate for domestication. It is relatively quick maturing - producing fruit in just two to three years - as well as being responsive to breeding for size and sweetness, among other qualities. "It's also tasty and produces a lot of fruit. They are rich in vitamins A and C and have a lot of energy - calories - per fruit," Crawford added. "The flavor is amazing. I like eating them raw mostly, but peach pies and peach crumble are right up there." Radiocarbon dating of the pits showed peaches split from their wild ancestors as long as 7,500 years ago. Peaches went from being small with very little flesh to a robust fruit like we see today. Crawford said the wild ancestor of the peach apparently is extinct. "In China, the peach is a symbol of long life and has a significant role to play in Chinese culture," said Crawford, adding that conventional wisdom had been that the peach originated somewhere else in China. It was a capable Chinese culture called the Kuahuqiao that seems to have begun peach domestication. Rice domestication was already under way in the area. "They were settled in small towns, had a broad spectrum of foods and other resources, had dugout canoes and were burning areas of the landscape for managing the local ecosystems," Crawford said. They also raised pigs, kept domesticated dogs, stored large amounts of acorns, used wooden tools and made high-quality wheel-turned pottery, Crawford said.
