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.

Let me give you an 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
The answer to this example can be: 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.
Here is why: 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.

OK. solve this:
Paragraph: The U.S. Department of Agriculture said 73,500 chickens were destroyed at the facility and will not enter the food system. The H7 avian influenza can be deadly to chickens and turkeys. “Bird flu” is a catch-all phrase for a variety of influenza viruses that spread among poultry. They can be very contagious and deadly among birds, but rarely spread to humans. That said, deadly human flu pandemics have been sparked by viruses that first emerged in birds, and health officials closely track what’s killing poultry. Flu can spread from birds to humans through the air, or when people touch a bird or an infected surface and then touch their eye, nose or mouth. The affected Tennessee breeder supplies the food company Tyson Foods Inc. The company said Monday that it doesn’t expect its chicken business to be disrupted, but the outbreak sent jitters through Wall Street. Shares of Tyson, based in Springdale, Arkansas, fell and the news dragged down shares of other companies in the sectors as well. “We’re responding aggressively, and are working with state and federal officials to contain the virus,” Tyson said in a company release. The company said it already tests all of its flocks for the virus before they leave farms “out of an abundance of caution.” Results are known before the birds are processed, the company said, and animals are not used if bird flu is detected. Tennessee’s Department of Agriculture is not identifying the farm where the chickens were destroyed, saying only that it is located in the state’s Lincoln County, which is just west of Chattanooga and borders Alabama. Only one commercial chicken farm in Alabama was within the six-mile radius, the state said, and all the birds there tested negative for the flu. The Alabama farm was also used by Tyson, according to the state. Alabama said it also began testing chickens in people’s backyards within the affected area, and all the tests have come back negative so far. There have been bird flu outbreaks in China and in Europe in recent months, though they are of differing strains. The USDA said Monday that it does not yet know what type of H7 bird flu is affecting the chickens in Tennessee, but will know within 48 hours. Shares of Tyson Foods Inc. fell $1.61, or 2.5 percent, to close at $61.99 Monday. Shares of Sanderson Farms Inc., based in Laurel, Mississippi, dropped $1.86, or 2 percent, to close at $92.53 and shares of Greeley, Colorado-based Pilgrim’s Pride Corp. fell 25 cents, or 1.2 percent, to close at $20.70. Claim: Bird flu found at Tyson Foods chicken supplier.

Tens of thousands of chickens have been destroyed at a Tennessee chicken farm due to a bird flu outbreak and 30 other farms within a six-mile radius have been quarantined.
