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.

The study to be published on Wednesday in the Journal of Neuroscience differs from many other pot-related research projects that are focused on chronic, heavy users of cannabis. The collaborative effort between Northwestern University's medical school, Massachusetts General Hospital and Harvard Medical School showed a direct correlation between the number of times users smoked and abnormalities in the brain. "What we're seeing is changes in people who are 18 to 25 in core brain regions that you never, ever want to fool around with," said co-senior study author Dr. Hans Beiter, professor of psychiatry and behavioral sciences at Northwestern University. In particular, the study identified changes to the nucleus accumbens and the nucleus amygdala, regions of the brain that are key to regulating emotion and motivation, in marijuana users who smoke between one and seven joints a week. The researchers found changes to the volume, shape and density of those brain regions. But more studies are needed to determine how those changes may have long-term consequences and whether they can be fixed with abstinence, Beiter said. "Our hypothesis from this early work is that these changes may be an early sign of what later becomes amotivation, where people aren't focused on their goals," he said. The study, which was funded in part by the National Institute on Drug Abuse and the White House Office of National Drug Control Policy, comes as access to pot is expanding following 2012 votes in Washington state and Colorado to legalize its recreational use. The drug remains illegal under federal law. Medical pot is allowed in 20 U.S. states. Pot legalization advocates make the argument that marijuana is safer than alcohol a central part of their campaigns. Other research has found drinking alcohol alters the brain, Beiter said. But while researchers do not know exactly how the mental rewiring seen in pot users affects their lives, the study shows it physically changes the brain in ways that differ from drinking, he said. This latest study fits with other research showing marijuana use has significant effects on young people because their brains are still developing, and Beiter said he has become convinced that marijuana should only be used by people under 30 if they need it to manage pain from a terminal illness.
Answer:
Casual pot use causes brain abnormalities in the young: study.
