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: The latest work, which appears in the journal PNAS, Proceedings of the National Academy of Sciences of the United States of America, also suggests that different policy steps might be needed in that case. "My study essentially shows that the methods used and analyses presented in the original research are insufficient to rule out other explanations (for lower IQ)," said Ole Rogeberg, an economist at the Frisch Centre for Economics Research in Oslo, to Reuters. The Dunedin Multi-disciplinary Health and Development Study is an ongoing report produced by New Zealand's University of Otago, monitoring 1,037 New Zealand children born between April 1972 and March 1973. The study followed them for 40 years. The participants were periodically tested for IQ and other indices including drug taking, and in 2012 clinical psychologist Madeline Meier produced a study saying there was a link between teenage cannabis use and a lower IQ. Researchers in the Meier study compared the IQ trends of people who never smoked cannabis with four groups of those who did: people who smoked, people who scored as dependent in a follow-up survey, those who scored as dependent twice and those who scored as dependent three times. The study found IQ declines increasing "linearly" with cannabis use, Rogeberg wrote in PNAS. The crucial assumption in the Meier study is that cannabis use is the only relevant difference between the groups tested, he said. His use of a simulation model showed that it may be premature to draw a causal inference between marijuana use and falling IQ scores. For one thing, other writing about the Dunedin group on which Meier's study is based suggest that early cannabis use is more common for people with poor self-control, previous conduct problems, and high scores on risk factors linked to low family socioeconomic status, he wrote. Given these factors, young people from lower status families tended to end up in less intellectually demanding environments, whether by choice or by circumstance, which would increase the difference in IQ levels as they aged. "We know that the researchers have measured the IQ of the participants at various ages in childhood - but we don't know if the IQ changes were similar for the different cannabis-using groups before their cannabis use," he told Reuters. "We don't know how much of the change in IQ we can explain by differences in education, jail time, occupational status, etc and whether this affects the estimates in the paper."
Output:
Study casts doubt on link between cannabis, teen IQ drop.
