Input: Consider 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.

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.


Input: Consider Input: Paragraph: "Major industries in Wisconsin have sustained significant economic losses during the coronavirus pandemic, and nowhere is that more apparent than in the tourism sector. Wisconsin plays host to about 112 million tourists in a year, according to the WorldAtlas website, and 2019 was ""a record setting year, and the largest year for Wisconsin in at least a decade"" said Wisconsin Secretary of Tourism-designee Sara Meaney. However, the loss of revenue in 2020 is massive, she said. In a May 24, 2020, appearance on the WISN-TV (Channel 12) show ""UpFront,"" she said, ""Unemployment in our state in general is at about a quarter of our population. It’s actually over 50% of travel and tourism-related jobs that are now facing unemployment."" Meaney went on to say that just in the weeks since the pandemic hit, the state has lost more than a billion dollars in tourism dollars. ""Since the week ending March 14, Wisconsin actually saw a drop in tourism spending compared to last year of $1.7 billion,"" she said. Wisconsin’s tourism industry should come back a bit this summer. Some northern resorts have opened and state campgrounds reopened June 10, according to the Wisconsin Department of Natural Resources. But that tourism recovery could be an uphill climb if Meaney is correct that year-over-year weekly travel spending in the state has dropped $1.7 billion since March. Let’s take a look. Craig Trost, Wisconsin Department of Tourism communications director, pointed PolitiFact Wisconsin to the U.S. Travel Association, which commissioned a study by Tourism Economics, the firm the department uses for its economic impact data. The U.S. Travel Association is a national, non-profit organization representing the travel industry, with various sectors — including transportation, lodging, retail, recreation, leisure and entertainment and food service, meetings and trade shows. Adam Sacks, president of Tourism Economics, in an email to PolitiFact Wisconsin, explained that the analysis is based on a combination of factors: daily hotel data (nights and revenue) from STR, a research company that tracks the hospitality industry; flight data (seats and passengers) from Airline Data Inc. and the Transportation Security Administration; and drive travel data (outside 50 mile radius) from Arrivalist based on mobile device data. Trost said the week ending March 14 was significant because that is when COVID-19 began significantly impacting tourism spending. ""Since the beginning of March, the COVID-19 pandemic has resulted in over $176 billion in losses for the U.S. travel economy,"" the report states. According to the report, Wisconsin’s  year-over-year net change in weekly travel spending from the week ending March 28 to the week ending May 16 was down about $200 million each week. When going back earlier in March, the report notes losses for the week ending March 14 at $17 million and the week ending March 21 of $50 million. That brings the total to $1.775 billion. Romy Snyder, CEO/President of the Wisconsin Dells Visitor and Convention Bureau, said it will take time to correctly analyze and know the  financial impact of COVID-19 on Wisconsin Dells. ""We do know the loss of visitors has been detrimental to the local tourism economy,"" Snyder said in an email. ""According to 2019 numbers, the spring and summer seasons account for 66% of direct visitor spending in Wisconsin Dells."" Snyder said area businesses are ready to welcome visitors. ""Wisconsin Dells’ businesses are working to accommodate current visitors to the area in a safe manner by increasing sanitation procedures and limiting capacities and hours of operation,"" Snyder said. ""We know Wisconsin Dells has strong brand awareness in the Midwest, which will help our area when people are ready to travel and are looking for an accessible vacation destination with a diversity of activities."" Jon Jarosh of Destination Door County said area businesses have been getting ready and opening up. ""Everybody has a little different protocol in terms of what they’re going to allow at their particular business,"" Jarosh said on the same ""UpFront"" program where Meaney appeared via remote. ""We’re asking our visitors and residents that are out and about to just respect the individual businesses and what they are asking for. But by and large most businesses are going to be asking that their customers do wear a face covering of some sort and also just practice social distancing guidelines."" A major Dells attraction, Noah’s Ark water park, set its opening date for June 20, the first day of summer. The water park plans a number of precautions in line with recommendations from the Centers for Disease Control and Prevention. Those precautions include social distancing and limiting capacity not only in the park itself but also on specific attractions and in buildings. The park is requiring guests to RSVP for the day they want to visit, and visitors must buy tickets in advance online. Walk-up tickets will not be sold. Meaney said the state’s tourism losses have topped $1.7 billion since March. Data from weekly studies commissioned by the U.S. Travel Association, an organization with over 1,100 members nationwide, found that beginning the week ending March 14, when the COVID-19 crisis first began to significantly impact tourism spending, Wisconsin was down $17 million compared to a year earlier. The drop in year-over-year travel spending in the state mounted weekly, with the latest available report reporting a drop of $214 million for the week ending May 16. That brings the state tourism sector drop to $1.775 billion since the week ending March 14. Claim: “Since the week ending March 14, Wisconsin actually saw a drop in tourism spending compared to last year of $1.7 billion.”

Output: Decrease in tourism dollars became apparent the week of March 14, with a year-over-year drop of $17 million. Year-over-year decreases continued to mount, with drops of about $200 million per week statewide. A study commissioned by the U.S. Travel Association found year-over-year decreases totaled $1.775 billion from March 14 to May 16.


Input: Consider Input: Paragraph: The Boehringer Ingelheim drug Micardis, or telmisartan, is  typically used in patients with heart failure, but the study  found it worked as well as the ACE inhibitor ramipril, marketed  in the United States as Altace by King Pharmaceuticals Inc.    “We have one more alternative to use,” said Dr. Salim Yusuf  of McMaster University in Ontario, Canada. “This is probably  key for the 20 to 30 percent of people who don’t tolerate an  ACE inhibitor,” said Yusuf, who presented the study at a  meeting of the American College of Cardiology in Chicago. Telmisartan is an angiotensin receptor blocker, or ARB. Ramipril is an angiotensin converting enzyme, or ACE,  inhibitor. Both act on a compound called angiotensin in  different ways to regulate blood pressure. A team of international researchers compared the drugs in a  study of more than 25,620 patients with heart disease or  diabetes and other heart risk factors, but not heart failure. Telmisartan and ramipril alone worked equally well to  reduce cardiovascular death, stroke, heart attack or  hospitalization for heart failure, but telmisartan was easier  to tolerate than ramipril, with fewer patients experiencing  cough or other side effects. Micardis is the first ARB to be shown to have heart  benefits in patients who do not have heart disease. But since  the drug is more costly than the typical ACE inhibitor, the  study may not change practice, doctors said. “The newer drug is certainly not better,” said Dr. Steven  Nissen, a cardiologist from the Cleveland Clinic. “The drugs were equivalent in the trial, which means that  the same results can be achieved with an ACE inhibitor,” Nissen  said in an interview. “I think most physicians will choose the  drugs that are generically available,” he said. The study, published online in the New England Journal of  Medicine, also tested to see if Micardis combined with an ACE  inhibitor might work even better. But the researchers found the  combination caused a number of negative side-effects in  patients who do not have heart failure. Yusuf said the findings mean doctors need to be careful not  to use both drugs in patients. “What was even more important  was adding the two together could cause harm,” he said. Claim: Blood pressure drug Micardis cuts heart risk: study.


Output: The blood pressure drug Micardis was as  effective in preventing serious heart problems in high-risk  patients as certain older drugs, but with fewer side effects,  international researchers said on Monday.
