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: Sandbar and dusky sharks have been sighted around the power plant for decades, but scientists only started collecting data two years ago. Although they are still trying to count the smatterings of sharks nearby, researcher Aviad Scheinin said the hundreds flocking exclusively to the Hadera power plant every winter qualifies as "a legitimate and rare phenomenon." "The paradox that we see here is that this is not a natural environment ... and you cannot see it anywhere else in the vicinity," said Scheinin, manager of the top predator project at the Morris Kahn Marine Research Station, established by the University of Haifa. "This phenomenon is influenced and created by men, both with the power plant and the sea's increasingly warm water." The shifting climate of the Mediterranean Sea has been creating a bizarre boon for sharks, which thrive in and chase warm water. Expert say the warm water stimulates shark metabolisms, improves their breathing cycles and facilitates their pregnancies. "The spectacle is logical, but still very mysterious," said Alen Soldo, co-president of the Shark Specialist Group at the International Union for Conservation of Nature based in Switzerland. He said the power plant's water temperature 10 degrees warmer than the rest of the sea is what likely attracts the sharks to Hadera from deeper, colder waters during the winter season. Beyond this, though, a great deal remains unknown. "We know sharks love this water, and we can hypothesize, but we can't say with certainty exactly why," he said. Soldo added that although he hadn't heard of sharks congregating at power plants outside Israel, he could name a few other Mediterranean hotspots, such as coral reefs near Beirut, where sharks swarm in a similarly random way, perhaps driven by salinity and temperature levels. Scientists say the Mediterranean Sea has never been warmer, both because of climate change and the recent expansion of the Suez Canal, which opened the floodgates to Red Sea waters, among the warmest in the world. A recent study, published last fall in the journal Nature Climate Change, found that climate change is steadily heating the Mediterranean Sea by 0.4 degrees every decade, making the region among the hardest hit in the world. "The winters are not as cold as they used to be here, and they are no longer a limiting factor for sharks," Scheinin said. "Many new shark species are coming to the eastern Mediterranean from colder areas and establishing populations." On a recent trip, Scheinin steered his small boat of researchers along the coast and cut the motor. The team bobbed in the currents of the power plant discharge, straining to spot slender shadows whipping by in the turquoise water. A sudden churning in the water jolted the crew to action. A five-foot-long (1.5 meter-long) sandbar shark, ensnared by ropes, popped up at the boat's ledge. The researchers leaned over and wrangled with it, planting a high-tech tag on its dorsal fin to track its movements before setting it free. "It's ironic that all of our knowledge of sharks currently comes from the very fisheries that are threatening them," said Eyal Bigal, the lab manager of the project. The Morris Kahn Station's top predator team is working to change this, pulling together the first comprehensive body of data about the understudied and endangered Mediterranean shark species. Overfishing, spurred by demand along with lax fishing laws in neighboring countries like Lebanon and Syria, has depleted the Mediterranean shark population by over 90 percent since the 1950s, researchers say. An absence of top predators imperils the balance of the entire marine ecosystem. "If you erase the ones at the top, the food chain will collapse," Soldo said. "New species may emerge and start preying on populations crucial to human food security. Whole life forms may go extinct." Hadera's hotspot for sharks is now attracting visitors curious about the creatures and the threats they face. The municipality and Israel's Nature and Parks Authority, among other groups, are partnering to build an observation center. Last month, they launched a lecture series to educate tourists about shark behavior and protection. Scheinin said studying the sharks in Hadera could be a harbinger that "helps us assess what will happen to different species when waters elsewhere reach the temperatures we have here now."
Output:
Sharks drawn to warm waters by Israeli coastal power plant.
