Example Input: Paragraph: The Midwest was the hardest-hit region, as temperatures  plunged below zero Fahrenheit (minus 18 degrees Celsius). By nightfall the mercury was hovering at 0F in Chicago, 7F (minus 14C) in Detroit and minus 21f (minus 29C) in Minneapolis. Local television pictures showed the Chicago River and Lake Michigan filled with chunks of ice. The brutal blast known as the polar vortex is a stream of cold air that spins around the stratosphere over the North Pole, but whose current has been disrupted and is now pushing south into the United States. Officials warned Chicago residents, accustomed to chilling winters, to expect an unusually deep and dangerous freeze. Even the city’s supply of its signature deep-dish pizza was affected: The Lou Malnati’s chain announced it would stop taking delivery orders at 8 p.m. on Tuesday. “This could possibly be history-making,” said Ricky Castro, a National Weather Service meteorologist in Romeoville, Illinois. As much as two feet (60 cm) of snow was forecast in Wisconsin, and six inches (15 cm) in Illinois. Snow was expected through Wednesday from the Great Lakes region into New England. Some Chicago residents found warmth inside the Harold Washington Library Center, which planned to stay open on Wednesday. Gilbert Rothschild, 79, walked through a corridor wearing three sweaters and an undershirt underneath his parka. “The more layers, the more you’re insulated,” he said. Rothschild, the president of a liquor retailer, said he planned on keeping his stores open on Wednesday, figuring customers who were not working might want to pick up something to keep them feeling warm at home. Many Midwest cities opened warming shelters. Regional governments closed hundreds of schools and airlines canceled more than 2,000 flights, according to the Flightaware flight tracking website. Many had been destined for Atlanta, where the National Football League’s Super Bowl will take place on Sunday. Amy Patterson, a vice president at the Atlanta Super Bowl Host Committee, said there would still be time for fans to fly to Atlanta for the game, with the National Weather Service forecasting a high of a balmy 58F (14C) on Sunday. A low of minus 10F (minus 23C) was forecast in Chicago and elsewhere in northern Illinois on Wednesday. But with the wind chill factored in, temperatures will feel as low as minus 50F (minus 46C) through Thursday, the National Weather Service reported. Temperatures could reach lows of minus 30F to minus 40F (minus 34C to minus 40C) in parts of the Northern Plains and Great Lakes on Wednesday, the NWS said. The freezing weather may have killed a man in Rochester, Minnesota, who was found dead outside his home on Sunday, according to a report by WCCO, a local CBS affiliate. Rochester police officials did not respond to a request for comment. Jim Hayes, a National Weather Service meteorologist, warned that frostbite was possible within 10 minutes in the intense cold. For many across the region, life ground to a halt. In Chicago, home to the nation’s third-largest school system, officials plan to cancel classes for all 360,000 students on Wednesday due to the weather. Detroit also said all public schools would close, and Michigan State University said it would suspend classes, only the seventh time it has done so because of weather since 1855. The Chicago Zoological Society said it would shut Brookfield Zoo for only the fourth time in its 85-year history on Tuesday and Wednesday. According to the National Weather Service, the coldest recorded temperature in Chicago was minus 27 degrees (minus 33C) on Jan. 20, 1985. Officials in Des Moines, Iowa, opened warming shelters, but also suggested residents could stay warm inside shopping malls. In Georgia, Governor Brian Kemp shut government offices in 35 counties on Tuesday, and schools across parts of the state were also closed. In Fargo, North Dakota, where the temperature dropped to minus 24F (minus 31C), Dan Hallock, an advertising executive, marveled that people were still working outside as he bought coffee. “The garbage men of Fargo have my utmost respect,” he said. Claim: Polar vortex freezes U.S. Midwest with snow, dangerously cold air.
Example Output: A blast of Arctic air from the polar vortex brought dangerous, bone-chilling cold to a wide swath of the United States on Tuesday, stretching from the Dakotas through Maine, with snow expected as far south as Alabama and Georgia.

Example Input: Paragraph: "In his August Facebook Live video, Gov. Eric Greitens encouraged viewers to submit their questions. One viewer asked, ""What do we do for our veterans except use them as our reason to get mad when it fits our agenda?"" In response, Greitens touched on providing jobs for veterans, in addition to citing the rate of veterans graduating from treatment courts in Missouri. ""Our veterans in our veterans court, are graduating — 73 percent of our veterans are graduating from drug courts,"" Greitens said. ""By contrast, I think most of the people in the very good drug court program — the graduation rate’s like 53, 55 percent. The point of that is that drug courts are working for veterans."" We were wondering: Are 73 percent of veterans graduating from treatment courts? While we never heard back from Greitens’ spokesman, a Supreme Court of Missouri spokeswoman pointed us in the direction of where those numbers came from. According to the Missouri Courts website, treatment courts began as a way to battle increasing substance abuse problems. Treatment courts have existed in Missouri for nearly 25 years. The first treatment court was started in 1993 in Jackson County. Legislation in 2013 established the first veterans treatment courts programs, which ""are hybrid drug and mental health court dockets that use the treatment court model to serve veterans struggling with addiction, serious mental illness and/or co-occurring disorders,"" according to a treatment courts fact sheet. As of August 2017, there were 147 treatment court programs throughout the state. Of those, 12 are veterans treatment courts, with the remaining being adult, juvenile, family and DWI courts. Veterans can be accepted into treatment courts for drug-involved offenses and DWI offenses, Beth Riggert, communications counsel for the Supreme Court of Missouri, wrote in an email. According to the treatment courts fact sheet, ""The graduation rate for all programs in fiscal 2017 exceeds 61 percent."" However, the most recent data on veterans treatment courts is from calendar year 2016, Riggert said. In that time frame, there were a total of 247 veterans participating in veterans treatment courts in the state, Riggert said. However, because the program is rolling, only a total of 82 veterans exited the program in 2016. Of those, 60 successfully graduated the program and 22 did not. That translates to a success rate of 73.17 percent, or just about what Greitens said. Since 2011, the graduation rate from veterans treatment courts has steadily been increasing as more veterans have gone through the program. Greitens also said, ""By contrast, I think most of the people in the very good drug court program — the graduation rate’s like 53, 55 percent."" Because we were unable to reach Greitens’ spokesman for comment, we are unsure which specific treatment courts program Greitens was referring to when he said ""the very good drug court program."" However, Riggert elaborated on the graduation for other treatment court programs. In the same period, the graduation rate from adult drug courts was 52 percent, and the graduation rate from DWI courts was 90 percent, Riggert said. While Greitens is correct that the veterans treatment courts’ graduation rate was higher than some, such as the adult drug court’s rate, it is still not as high as the DWI court’s graduation rate of 90 percent. However, Riggert said it may not be accurate to compare graduation rates between treatment courts to prove one program’s success. ""The various types of treatment court programs are distinct, and so it is not helpful to try to make a side-by-side comparison,"" Riggert said. While 73 percent of veterans exiting the program did graduate in 2016, it is unclear how many veterans who graduate from the program have to return for additional treatment. ""Because veterans treatment courts are relatively new, we do not yet have sufficient quantifiable data from which to determine recidivism rates for these programs,"" Riggert said. Greitens said, ""73 percent of our veterans are graduating from drug courts. By contrast, I think most of the people in the very good drug court program — the graduation rate’s like 53, 55 percent. The point of that is that drug courts are working for veterans."" While the overall numbers are small, Greitens is correct that in 2016, 73 percent of veterans successfully completed treatment court. Over the same time period, the overall graduation rate from adult treatment court was 52 percent, officials say. However, officials also pointed out that the two programs are not identical, which makes comparing them imprecise. In addition, while graduation rate is one measurement of success, it’s not the only one, and as Riggert noted, veteran treatment courts are so new that no data on recidivism rates have been collected." Claim: Seventy-three percent of our veterans are graduating from drug courts. By contrast, I think most of the people in the very good drug court program — the graduation rate’s like 53, 55 percent. The point of that is that drug courts are working for veterans.

Example Input: Paragraph: It said Thursday that two of the four were patients at Advocate Christ Hospital in Oak Lawn within the past two months. The agency says it will visit the hospital this week to test its water and that the hospital is working with it to strengthen its water management. The agency says it has recommended the hospital inform patients and families about Legionella bacteria and work to identify other potential cases of the disease. Water containing naturally occurring Legionella bacteria can be aerosolized through cooling towers, showers, hot tubs, and decorative fountains and, when inhaled, cause Legionnaire’s disease, which is a serious lung infection. Claim: 4 cases of Legionnaires’ disease investigated at hospital.
Example Output:
The Illinois Department of Public Health says it’s investigating four cases of Legionnaires’ disease in individuals at a suburban Chicago hospital.
