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.

After Germany's top administrative court on Tuesday allowed local authorities to bar heavily polluting diesel cars in major cities, the federal government is scrambling to find ways to avert driving bans that would hurt consumers and automakers. Environmental and motorist lobbies are raising the pressure on Volkswagen (VW) and its peers to modify the exhaust systems of older diesels which they say are a major source of toxic nitrogen oxide emissions that can cause respiratory disease. "I don't want to say now that I'm ruling it out," VW Chief Executive Matthias Mueller said on Friday at an auto industry event. But he voiced misgivings. Hardware changes would cost between 1,500 ($1,845.30) and 7,000 euros per car, and the development as well as testing of new exhaust cleaning systems would take 2-3 years, Mueller said. Also, retrofitted vehicles might consume more fuel and emit more carbon dioxide, which would affect the level of car tax, he added. Of the 15 million diesel cars on Germany's roads, only 2.7 million are equipped with the latest Euro-6 emissions technology. Research firm Evercore ISI has estimated that upgrading the exhaust cleaning of the 6 million Euro-5 vehicles could cost up to 14.5 billion euros ($17.9 billion). "I would compare hardware changes on a Euro-5 vehicle to an open-heart surgery," Mueller said. There is no way that VW could shoulder major costs for such modifications as it is stretched by the costs and fines related to its "Dieselgate" emissions scandal, he said. "We had to pay about 25 billion in America, we cannot again pay 17 billion for hardware refits," Mueller said. "That is simple not possible."
Answer:
Diesel vehicle refits costly and could affect performance, Volkswagen says.
