[EX Q]: 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.
[EX A]: 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.

[EX Q]: Paragraph: Moncef Slaoui, a former GlaxoSmithKline executive, will lead “Operation Warp Speed,” Trump’s push to accelerate the vaccine development process for COVID-19, according to an administration official. Slaoui is to serve in a volunteer capacity, and will be assisted by Army Gen. Gustave Perna, the commander of United States Army Materiel Command. The move comes as the president and White House aides hope to produce vaccines for the coronavirus faster than what many scientists believe is realistic. The administration is aiming to have 300 million doses to distribute to Americans by the end of the year, believing a reliable vaccine is the only way to promote an economic rebound. “Operation Warp Speed” is operating largely independently of the existing White House coronavirus task force, which is also shifting its focus toward vaccine development. The initiative is being promoted by White House senior adviser Jared Kushner, and involves officials from the Defense Department and the Department of Health and Human Services. On Tuesday, Dr. Anthony Fauci, the government’s top infectious disease expert, said a vaccine would not be available by the beginning of the next academic year. “The idea of having treatments available or a vaccine to facilitate re-entry of students into the fall term would be something that would be a bit of a bridge too far,” he said, “even at the top speed we’re going.” Claim: Trump to name former pharma exec as vaccine czar.
[EX A]: President Donald Trump is set to name a former pharmaceutical executive to lead his administration’s all-out effort to produce and distribute a coronavirus vaccine by the end of the year.

[EX Q]: Paragraph: In January 2018, social media users began pondering a photograph seemingly showing a variety pack of Gatorade brand sports drink offered for sale at a Costco warehouse store in Seattle, priced at $26.33. What threw viewers for a loop was that the price of the drink itself was only $15.99, with another $10.34 (a markup of 65%) being added to the cost for something identified as “”City of Seattle Sweetened Beverage Recovery Fee”:  The photograph was real, and it referenced a Sweetened Beverage Tax imposed on the distribution of sweetened beverages in the city of Seattle beginning 1 January 2018, at a rate of is 1.75 cents per fluid ounce:  The excise tax includes sodas, energy and sports drinks, fruit drinks, sweetened teas, and ready-to-drink coffee drinks.

Any beverage consisting of 100 percent natural fruit or vegetable juice with no added sweetener. Any beverage that contains fewer than 40 calories per 12-ounce serving. Alcoholic beverages. This exclusion does not apply to bar mixers that sweeten alcoholic drinks. Claim: Seattle has imposed an excise tax on the distributors of sweetened drinks.
[EX A]:
The stated purpose of the tax and the proceeds derived therefrom are to expand access to healthy and affordable food, close the food security gap (i.e., assist those who do not qualify for SNAP benefits), promote healthy nutrition choices, reduce disparities in social, developmental, and educational readiness and learning for children, assist high school graduates to enter college, and expand services for the birth-to-five population and their families.
