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.

Let me give you an 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."
The answer to this example can be: Some appendicitis cases may not require 'emergency' surgery
Here is why: 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.

Scientists say fossils found in Morocco suggest the practice of forming orderly lines may date back 480 million years and could have had evolutionary advantages. Their study, published Thursday in the journal Scientific Reports, describes groups of blind trilobites known as Ampyx all facing in the same direction, apparently maintaining contact via their long rearward spines. The researchers from France, Switzerland and Morocco analyzed the fossils and concluded that the tiny trilobites, which look similar to modern horseshoe crabs, probably intentionally formed a queue as they swarmed along the prehistoric sea floor. "Given the scale of the patterns seen, this consistent linearity and directionality is unlikely to be the result of passive transportation or accumulation by currents," they said. Jean Vannier, a researcher at the University of Lyon, France, who co-authored the study, said possible reasons for this group behavior include environmental stresses or reproduction. Similar behavior is also found in modern-day members of the extended family of arthropods that trilobites belonged to, such as caterpillars, ants and lobsters, who band together for protection or to find mates. "Living and moving in groups seems to have rapidly represented an evolutionary advantage among ancient animals," Vannier said. Lucy McCobb, a paleontologist at the National Museum Wales who wasn't involved in the study, said that while similar 'conga lines' of fossilized Ampyx have been reported before, the researchers behind the study had built "a very strong case for the intentional lining up of the trilobites in response to some cue." "These fossils give us a wonderfully vivid glimpse into the lives of these very ancient but clearly sophisticated creatures," she said. Vannier said the findings support the idea that collective behavior like forming lines emerged around the same time or shortly after animals first developed sophisticated nervous systems and sensory organs. He and fellow researchers said re-examining 520 million-year-old fossils of shrimp-like creatures found in China could offer evidence that such behavior began even earlier.
Answer:
Queuing for eternity: Fossils show lining up is primal urge.
