Example Input: Paragraph: George W. Bush stood with a bullhorn on a pile of rubble after the 9/11 attacks on lower Manhattan and promised that the people who were responsible “will hear all of us soon.” Barack Obama was in office for just a few months when the first reports came in about the H1N1 virus, which would eventually be declared a pandemic  like today’s new coronavirus. Most American presidents will confront a crisis — or crises — before they leave office, whether it is a natural disaster, war, economic downturn, public health threat or terrorism. What matters is how they respond, historians say. “The number one thing a president can do in a moment like this is try to calm the nation,” said Julian Zelizer, a presidential historian at Princeton University. It’s what Franklin D. Roosevelt did during an extraordinary 12 years in office, guiding the nation through a bleak period of Depression-era unemployment, a severe Midwest drought known as the Dust Bowl and battle against the Nazis and Japanese in World War II. During the influenza of Wilson’s time, which killed an estimated 50 million people worldwide, including about 675,000 in America, presidents were not involved in public health issues in the same way that President Donald Trump has become engrossed in the U.S. effort against the new coronavirus. Such issues were left for public health professionals at the state and local level. “Wilson never issued any public statement whatsoever,” said John M. Barry, author of “The Great Influenza,” a book about the 1918 flu. “He was entirely focused on the war. Period.” In fact, Wilson was so focused on the post-war peace talks he was participating in in Paris that he, too, ended up stricken with the flu. He recovered. Trump, on the other hand, seems intent on being the public face of the effort against what has become his most serious challenge in this reelection year. Trump, who has no scientific or medical training, now leads a daily White House briefing on coronavirus efforts by a task force he tapped the vice president to lead. Trump styles himself as a “wartime president” fighting an “invisible enemy” responsible for hundreds of deaths and thousands of infections in the U.S. - numbers that will continue to rise as the virus spreads — and a dramatic upheaval of everyday life. Millions of people have been ordered or urged to stay home for the foreseeable future, cut off from simple pleasures like going to restaurants, shopping malls or movies in a bid to slow the virus. But Trump’s crisis management has earned mixed reviews, with praise from many supporters and criticism from detractors, including mayors and governors who are desperate for Trump to more robustly use his authority to help them get much-needed protective gear and supplies for doctors and nurses. The president’s early attempts to minimize the severity of the situation, and to suggest that it was under control, have been panned, though he recently adopted a more urgent tone. But the damage has been done, said Steve Morrison, of the Center for Strategic and International Studies, citing lack of public trust due to Trump’s early handling of the situation. “Not having trust and confidence is a huge liability heading into something this catastrophic,” said Morrison, senior vice president and director of the Global Health Policy Center at CSIS. Obama was a few months into his first term in 2009 term when reports started coming in that April about the H1N1 flu. He addressed the situation that month, assembled a team and ultimately declared both a public health emergency and a national emergency to deal with the threat. “This is obviously a very serious situation, and every American should know that their entire government is taking the utmost precautions and preparations,” Obama said as he opened a White House news conference that month. He said public health officials had recommended that schools with confirmed cases consider temporarily closing, and that he had asked Congress for $1.5 billion in emergency funding to help monitor and track the virus, and to build a supply of antiviral drugs and other equipment. “Everyone should rest assured that this government is prepared to do whatever it takes to control the impact of this virus,” Obama said. Dr. Howard Markel, director of the University of Michigan’s Center for the History of Medicine, said Obama was “very hands on” during H1N1 — but not as visibly as Trump. Obama’s director of the Center for Disease Control and Prevention conducted daily briefings from Atlanta. “He took a step back because he allowed his experts to run the show,” Markel said of Obama. “He didn’t have to be in front of the podium, but you knew he was there.”  Nearly 12,500 deaths due to the H1N1 flu were reported in the U.S. between April 2009 and April 2010, when the World Health Organization declared an end to the pandemic. Obama spent nearly $1 billion and sent U.S. military personnel to West Africa to help with the response to an outbreak of Ebola  in 2014. Still feeling his way through his first year in office, Bush became a wartime president the instant hijackers recruited by the al-Qaida militant network flew commercial airliners with passengers into the World Trade Center, the Pentagon and a Pennsylvania field on Sept. 11, 2001. Days later, Bush stood atop the rubble and memorably spoke for the nation. “I can hear you!” Bush blared through the bullhorn as emergency responders cheered. “The rest of the world hears you! And the people – and the people who knocked these buildings down will hear all of us soon.”  Weeks after that appearance, Bush authorized military airstrikes against Taliban military installations and al-Qaida training camps in Afghanistan. U.S. military engagement in Afghanistan continues to this day. ___ This story has been corrected to reflect that Morrison’s first name is Steve, not Scott. ___ Bev Banks contributed to this report.

Example Input: Paragraph: A University of Iowa study shows the state’s contribution to the Gulf dead zone spiked 47 percent to 618 million pounds in 2016, based on five-year running annual averages. “Just based on water quality data, I think we can say we’ve not made much progress over the past 20 years in terms of nitrogen,” said Chris Jones, a research engineer at the UI’s IIHR-Hydroscience & Engineering. Environmentalists say the study raises new questions about the effectiveness of Iowa’s approach to improving water quality and its reliance on voluntary ag compliance. “We’ve been pouring state and federal money into cutting nutrient pollution for decades, and this highlights the fact that the voluntary approach is not working,” said Jennifer Terry, executive director of the Iowa Environmental Council. “We’re not headed in the right direction. ... We need to follow the lead of other states and pass some environmental laws that will actually reduce loads and result in cleaner water,” Terry said. The Des Moines Register reports that the news comes as Iowa marks the five-year anniversary of the Iowa Nutrient Reduction Strategy, a plan designed to cut by 45 percent the nitrogen and phosphorus levels that leave Iowa and feed Gulf hypoxia — or the dead zone. Oxygen levels within the zone are so low that marine life can no longer survive, threatening the Gulf’s seafood industry. Most of the nutrient losses come from farming, although the strategy also targets losses from urban wastewater and industrial operations. Last year, Iowa invested $420 million in those water quality improvements, including helping farmers plant cover crops, build terraces and tackle other conservation practices that hold nutrients in place. But farmers expanding their drainage tile systems — along with increasing hog, cattle and chicken feeding operations, which provide manure to fertilize crops — likely outweigh those conservation efforts, UI scientists say. The nutrient reduction practices “being implemented are a tiny, tiny portion of what needs to be done, and it’s occurring in a system that’s changing,” Jones said. “We appreciate all that is being done with nutrient management and conservation farming. Unfortunately, we’re just impacting too few acres with too few practices,” added Larry Weber, executive associate dean for UI’s College of Engineering. Jones wrote the study with Weber and Keith Schilling, another UI research engineer. Increased nutrient pollution in water creates problems for people and animals beyond the dead zone. High phosphorus levels can lead to toxic algae blooms that can befoul lakes, rivers and streams, potentially killing pets and making people ill. And the federal government limits the amount of nitrates in drinking water to 10 milligrams per liter. Higher levels can be fatal to babies under 6 months old. Increased levels translate to higher costs for utilities for nitrate removal. “We need a dramatic increase, a rapidly-scaled up increase in conservation practices and more funding,” said Cindy Lane, the Iowa Environmental Council’s water program director. Schilling said the study shows that targeting nutrient reduction investment in Iowa can have a significant impact downstream. “Iowa has a dominant role in this Gulf hypoxia issue,” Schilling said. “Let’s invest the resources here, where we really need it. “If we solve Iowa, we solve the Gulf,” he said. The UI study gives Iowans new information in the fight to reduce the nitrogen levels that flow from the state into the Mississippi and Missouri rivers, which make their way to the Gulf of Mexico. Looking at Iowa Department of Natural Resources data from 23 monitoring stations, the study shows Iowa on average over the past 18 years contributed 29 percent of the total nitrogen headed to the Gulf from the Mississippi-Atchafalaya river basin. The river basin is a massive watershed that includes all or part of 31 states. Iowa’s nitrogen impact was even greater in other watersheds. The state averaged 45 percent of the nitrogen levels going into the Upper Mississippi River basin, and 55 percent of the nitrogen going into to the Missouri River basin. “When you look at the entire Missouri (River) watershed, our land comprises 3.3 percent of the total area ... and Iowa contributes nearly 12 percent of the water,” Jones said. But “we contribute 55 percent of the nitrate,” he said. “The way that pencils out is that the amount of water coming from Iowa has seven times more nitrates than the rest of the Missouri River watershed,” Jones said. If Iowa’s contributions were removed, the Missouri River would have little nitrogen contributions in some years. “We really need to take seriously the Missouri River’s contribution as a driver for Gulf hypoxia,” Jones said. The growing concentration of livestock feeding operations in western Iowa might account for Iowa’s large contribution to the Missouri River nitrate levels, the scientists said. “People tend to dismiss livestock influences, but maybe there’s more to it than people give credit it for,” Schilling said, adding that it would require more study to determine the impact. Iowa’s nitrogen levels, based on running five-year annual averages, have been above the 2003 value for 10 consecutive years, the study says. The scientists say 2003 was the first year the five-year rolling average could be calculated, with data that starts in 1999. The goal of the Gulf Hypoxia Task Force, made up of federal, state and tribal leaders, “will be very difficult to achieve if nitrate retention cannot be improved in Iowa,” the report said. The task force, with Iowa Agriculture Secretary Mike Naig as chairman, seeks to reduce the dead zone to 1,900 square miles by 2035. The deadline was extended from 2015. Last year, the dead zone set a record, which, at 8,776 square miles, was more than four times the goal size. The report says about 90 percent of Iowa’s nitrogen levels “can be sourced to the 72 percent of the state’s land area that is in crop cultivation.” Iowa, an agriculture powerhouse, is a national leader in corn, soybean, pork, egg and beef production. “This intense production of carbohydrates and protein has resulted in the state being a leading contributor” to the nitrogen loads and Gulf hypoxia, the report said. Naig said farmers understand the important role they play in improving water quality and are scaling up efforts across the state “as we move from demonstration projects to larger, watershed-scale implementation projects. “We recognize that there is still a lot of work to be done, but we are on the right path,” said Naig, who adds farmers are working with more than 250 partners in 65 rural and urban demonstration projects. The UI scientists doubt that increased cropping is the reason for the increased nitrogen impact. Iowa’s cropped area has increased only 4 percent over the past 18 years, while other states’ farmed land has climbed 21 percent, particularly in Minnesota, North and South Dakota and Kansas. About 85 percent of Iowa’s acres are farmed, making it the fifth-highest in the nation, based on the 2012 U.S. Agriculture Census, so there are few acres left that can be brought into production compared with other states. “Iowa’s decline in the share of the region’s soybean area was especially pronounced, dropping from 18.6 percent in 1999 to 14.5 percent in 2016,” the report said. “One would expect our (nitrogen) contributions relative to the other areas would be diminished,” Jones said. “But the opposite has occurred.” Jones said it’s led the scientists to consider other factors. The scientists doubt that Iowa farmers are using significantly more fertilizer. “When we look at nitrogen sales data, it might change a little year over year. But on a per acre basis, that hasn’t changed a lot since 1990,” he said. And with little increase in corn and soybean acres, the scientists speculate that Iowa’s increased nitrogen levels could be coming from more drainage tiles. Or farmers could be using more manure as fertilizer from animal feeding operations. Without Iowa, the Gulf’s overall nitrate loads would have declined 43,400 tons over 18 years, based on five-year running annual averages, the scientists’ data show. Instead nitrate loads grew by 52,000 tons. “It’s pretty clear these loads from the Ohio basin have to be declining,” Jones said. “A lot that is coming from Indiana.” That state’s high level of cover crop adoption by farmers could be the reason, he said, and should be studied. Cover crops such as cereal rye slow the rate of water runoff, reduce erosion and improve soil fertility. Iowa also needs to honestly discuss the impact that drainage tiling has on nitrogen losses, Jones said. Iowa doesn’t collect data on how much underground drainage runs through the state, although officials estimate about 9 million acres are drained through tile. Environmentalists believe the number is much higher. Underground drainage tile helps improve yields by quickly removing excess water from fields. Iowa’s tiling system consists of a network of drainage lines that feed into large pipes. The massive network, first constructed in the 1920s, ’30s and ’40s, turned once swampy lands into some of the nation’s most productive farmland. But water quickly carried away by the tiling system misses cleansing that would naturally occur by filtering through soil or the roots of trees, shrubs and grasses in riparian buffers along streams. Des Moines Water Works unsuccessfully sued drainage districts in three north Iowa counties in 2015, claiming underground tiles funneled high levels of nitrates into the Raccoon River, a source of drinking water for 500,000 central Iowa residents. “We acknowledge that it’s important to track implemented conservation, and we encourage that,” Jones said. “But we also need to have the courage to talk about these things that drive the system in the other direction.” Terry said Iowa is “one of the most heavily tiled states in the nation,” and its 110-year-old law regulating the practice does little to protect water quality. ___ Information from: The Des Moines Register, http://www.desmoinesregister.com Claim: Study: Iowa nitrogen pollution in the water is getting worse.

Example Input: Paragraph: "Hostilities between the dairy industry and its competitors are flaring anew as alternatives to cow’s milk take up more space in the dairy case. That means the politicians can’t be far behind. U.S. Sen. Tammy Baldwin, a Wisconsin Democrat, spoke up Jan. 12, 2017 in a news release lauding herself as somebody who ""stands up for Wisconsin dairy farmers."" Baldwin wants Congress to pass the Dairy PRIDE Act -- officially known (at least to a few) as the ""Defending Against Imitations and Replacements of Yogurt, milk, and cheese to Promote Regular Intake of Dairy Everyday Act."" After two years of falling milk prices, she and other federal lawmakers want the U.S. Food and Drug Administration to enforce consumer regulations defining ""milk."" Is Baldwin right that imitation dairy products -- for instance, soy milk -- often differ nutritionally from dairy item? And is labeling them ""milk"" or ""cheese"" or ""yogurt"" against the law? To back that up, Baldwin’s office pointed us to nutritional labels, and to FDA regulations that plainly state: ""Milk is the lacteal secretion, practically free from colostrum, obtained by the complete milking of one or more healthy cows."" 'Against the law' To dairy officials, inclusion of the word ""milk"" on non-dairy products is a misappropriation of the popularity of cow’s milk. But competitors say coconut milk and soy milk have long histories and aren’t confused with dairy. What’s more, they note, the FDA doesn’t punish ""peanut butter"" for using the dairy term ""butter."" But the FDA in 2008 and 2012 did tell two makers of drinks labeled ""soy milk"" that under its regulations, such labeling was inappropriate because the products did not contain ""milk"" as defined by the agency. ""Soy drink"" or ""Soy beverage"" would be better, the agency said at the time. That -- and regulatory language allowing the FDA to declare a product misbranded and try to block its sale -- help Baldwin’s case. Federal regulations are part of the United States Code that is the law of the land. But to the frustration of the dairy industry, the agency has not consistently enforced that line of reasoning, allowing use of ""soy milk"" and ""almond milk"" and many others. Rebecca Cross, a San Francisco-based regulatory lawyer for food product companies, said the FDA may be viewing labels on a case-by-case basis and allowing use of dairy terms on plant-based products so long as the use is not misleading. Nathan Beaver, a food and drug lawyer with Foley & Lardner in Washington, D.C., explained that foods such as soy milk that have no FDA-written ""standard of identity"" must choose a ""common or usual"" name for their products. Courts, though, have jurisdiction over disputes on the issue and therefore get final say on the meaning of the FDA rules. On milk, courts so far have found that cow’s milk competitors are not misbranded if their names don’t confuse consumers, said Cross. The nutrition comparison Dairy alternatives, Baldwin said, ""contain a range of ingredients and nutrients that are often not equivalent to the nutrition content of dairy products."" This is a bit tricky to evaluate given that beverages labeled as some kind of ""milk"" now come from such diverse sources as soy, almonds, cashews, hemp, rice, oats, coconut and sunflowers. For help, we turned to Vandana Sheth, a registered dietician and spokesperson for the Academy of Nutrition and Dietetics, a leading organization of food and nutrition professionals. For starters, Sheth noted that dairy products can be a good source of calcium, vitamin D, protein and other essential nutrients. Soy milk provides close to the same amount of protein as cow’s milk. Rice milk typically provides minimal protein and is higher in carbohydrates. Almond milk is usually quite low in protein and also less calorically dense, she said. Plant protein tends to be of a lower quality than dairy proteins, though soy is close, said John Lucey, a food scientist who directs the Center for Dairy Research at the University of Wisconsin-Madison. Our own review of labels found that soy and almond beverages, like cow’s milk, are all relatively low calorie, low carbohydrate, low sodium drinks. They are all heavy with calcium. But they feature a different mix of vitamins and minerals, and fat content. Examples: soy milk has a lot of folate, while cow’s milk typically has none; cow’s milk contains some Vitamin C, but the soy, almond and hemp drinks we examined have none. Almond and soy milks feature some iron and fiber -- nutrients typically not found in cow’s milk. ""All the products profile differently,"" said Susan Levin, a registered dietitian and director of nutrition education for the Washington, D.C.-based Physicians Committee for Responsible Medicine. Bottom line: Baldwin’s nutrition observation is on target, based on a comparison of milk products. Our rating Baldwin claimed that imitation dairy products made from plants often differ nutritionally from the real thing, and labeling them ""milk"" or ""cheese"" or ""yogurt"" is ""against the law."" The nutrition point is accurate, and the legal point is partially so." Claim: "Imitation dairy products often differ nutritionally from those they mimic, and labeling them ""milk"" or ""cheese"" or ""yogurt"" is ""against the law."
