[EX Q]: Paragraph: Fitness experts say users of the fitness machine, which is a favorite among Army Rangers, Navy Seals, and “The Biggest Loser” television series, reap total body, calorie-busting rewards. “It’s a great and tough cardio piece,” said Neal Pire, an exercise physiologist with the American College of Sports Medicine. “Picture a step mill that combines the lower and upper body, and you have Jacobs Ladder. Except instead of steps, you have rungs.”  Because the user climbs with arms as well as legs more muscles are working and more calories are burned. “As a rule the more muscle mass you utilize during any activity, the greater the oxygen consumed, which is directly correlated to the calories you consumed,” said Pire, president of Inspire Training Systems, in New Jersey. “Unlike stair climbers, you can’t hold on to the sides.”  Jacobs Ladder was invented by Steve Nichols, a fitness champion who injured his knees and back, according to Bob Palka, president of Jacobs Ladder, LLC. “He wanted to come up with a good workout that didn’t impact back and knees.” said Palka, who bought the patent and assets from Nichols in 1994. “Effectively it’s just climbing a ladder,” Palka said. People using the machine are placed at a 40-degree angle to put the spine in a more neutral position, relieve the back of stress and engage core muscles. Palka said on Jacobs Ladder the person’s body weight is lifted over a 12-inch (30.5-centemeter) step for fuller range of motion than the eight-inches of a step mill. “You control the speed,” he said.” The faster you go the faster the runners (on the ladder) come.”  Palka said about 50 to 60 percent of his Jacobs Ladders go to health clubs; some 10 to 15 percent go to the military and physical therapy facilities, respectively. Jacobs Ladder landed a recurring role on the TV show “The Biggest Loser” after trainer Jillian Michaels fell in love with it. “It tends to get your heart rate up,” said Palka, adding that other users, such as the FBI and the Army Rangers, are drawn to the intensity of the workout. John Trail, general manager of a Fitness First health club in Arlington, Virginia, uses Jacobs Ladder in functional circuit and interval training. “You can go for time or you can go for feet,” said Trail. “It’s not a fast-moving piece, but the fact that you’re using every muscle group means you can do 100 feet, rest, jump off, do 10 kettlebell swings, 10 short interval sprints, and burn a lot more calories than you would on an elliptical.”  Trail said a rock climbing buddy likes to climb Jacobs Ladder wearing a back pack for an endurance workout. A self-described competitive person, Trail has even raced with it. “We have two machines side-by-side, so we’ll go for 1,000 feet as fast as possible,” he said. “In under 10 minutes you can get a really good workout.”  He also uses it on clients with joint issues to get their heart rates up quickly. But despite its virtues, Pire said it’s unlikely Jacobs Ladder will supplant the treadmill anytime soon. “The tougher the machine, the more seldom you see it,” he said. “I haven’t seen many seniors hop on. The older population is concerned about balance and falling. And there’s some skill involved in climbing a ladder. But fans are ardent. “Those who use it are almost religious,” he said. Claim: Jacobs Ladder climbers reap tough fitness rewards.
[EX A]: Jacobs Ladder, a moving, angled, climbing machine, may be named after the Biblical stairway to heaven, but it packs such a challenging workout people have dubbed it the stairway to hell.

[EX Q]: Paragraph: An image graphic purportedly featuring an excerpt from a speech President John F. Kennedy was scheduled to deliver on the day that he was assassinated was recirculated on social media in November 2018:  These lines were part of a speech JFK was slated to make to the Texas Democratic State Committee in the Municipal Auditorium in Austin, Texas, on the evening of 22 November 1963. President Kennedy never had the opportunity to deliver that speech, however, as he was assassinated earlier that day while his motorcade drove through Dealey Plaza in Dallas. A transcript of this undelivered speech is available via the John F. Kennedy Presidential Library and Museum. The excerpt included in this meme comes from the penultimate paragraph of that text: Finally, I said in Lubbock in 1960, as I said in every other speech in this State, that if Lyndon Johnson and I were elected, we would get this country moving again. That pledge has been fulfilled. In nearly every field of national activity, this country is moving again — and Texas is moving with it. From public works to public health, wherever Government programs operate, the past 3 years have seen a new burst of action and progress — in Texas and all over America. We have stepped up the fight against crime and slums and poverty in our cities, against the pollution of our streams, against unemployment in our industry, and against waste in the Federal Government. We have built hospitals and clinics and nursing homes. We have launched a broad new attack on mental illness and mental retardation. We have initiated the training of more physicians and dentists. We have provided 4 times as much housing for our elderly citizens, and we have increased benefits for those on social security. Almost everywhere we look, the story is the same. In Latin America, in Africa, in Asia, in the councils of the world and in the jungles of far-off nations, there is now renewed confidence in our country and our convictions. For this country is moving and it must not stop. It cannot stop. For this is a time for courage and a time for challenge. Neither conformity nor complacency will do. Neither the fanatics nor the faint-hearted are needed. And our duty as a party is not to our party alone, but to the Nation, and, indeed, to all mankind. Our duty is not merely the preservation of political power but the preservation of peace and freedom. So let us not be petty when our cause is so great. Let us not quarrel amongst ourselves when our Nation’s future is at stake. Let us stand together with renewed confidence in our cause–united in our heritage of the past and our hopes for the future — and determined that this land we love shall lead all mankind into new frontiers of peace and abundance. Kennedy was expected to deliver two speeches in Texas on the day that he was assassinated. The other, which was scheduled to take place at the Trade Mart in Dallas, was “recreated” by the Times of London and the creative Irish agency Rothco in March 2018: It took eight weeks to bring to life the 2,590 words John F Kennedy never got to speak. Sound engineers pulled 116,777 sound units from 831 of his speeches and radio addresses. These units were then split in half and analysed for pitch and energy. The half units, known as phones, were each about 0.04 seconds long and had to be tested next to each other to ensure that they did not clash. The W sound in weapons, for example, is not the same as the W sound in words. A portion of “JFK Unsilenced” recreation can be glimpsed below: Claim: "A passage from a speech JFK was supposed to deliver on the day he was assassinated stated that ""our duty as a party is not to our party alone, but to the Nation, and, indeed, to all mankind."
[EX A]: The words of President John F. Kennedy that the world never got to hear.

[EX Q]: Paragraph: Trump made the announcement at a Rose Garden news conference as he battled to show Americans he is aggressively addressing the health crisis after facing criticism that he was slow to react and played down the threat until the number of cases rose. Trump cautioned that Americans will have to make sacrifices and change their daily practices, a stark difference from two weeks ago when he said people should use common sense but otherwise not change their routines. “It could get worse. The next eight weeks will be critical,” he said. The president appeared on stage with members of his coronavirus task force and business executives after meeting them inside the White House over how to accelerate testing of Americans for the virus to better track the contagion’s spread. Shaking hands freely with the gathered business executives, the 73-year-old Trump later acknowledged he expected to be tested for the virus. He had come into contact with a Brazilian official last Saturday who later tested positive for coronavirus. “Most likely, yeah, most likely. Not for that reason but because I think I will do it anyway,” Trump said. “Fairly soon. We’re working out a schedule.”  “We have no symptoms whatsoever,” he said to a question about whether he should get a test. Trump said Walmart Inc  Chief Executive Doug McMillon had agreed to set up drive-thru testing at store parking lots across the country and that Alphabet Inc’s Google will create a website to help determine whether individuals need a coronavirus test. Trump shrugged off a question about whether he was responsible for what many experts have said was slow progress toward expansion of tests to track the virus. “I don’t take responsibility at all,” he said, blaming rules and regulations he inherited for the inability to mass produce the testing kits. Trump, who on Wednesday ordered citizens from 26 European nations not to enter the United States for 30 days as of midnight Friday, said his administration “may be adding” travel restrictions on the United Kingdom and a couple of other countries. As for whether Americans should take commercial flights, Trump was blunt: “If you stay home, it’s not bad. It’s not bad.”  The virus that emerged in central China in December has now spread to over 130 countries and territories and infected more than 138,000 people worldwide, according to the World Health Organization. It has so far led to 47 U.S. deaths after six more were reported on Friday in hard-hit Washington state and one in Colorado. Trump said his declaration of a national emergency will “unleash the full power of the federal government” to help states and territories in the fight. The announcement gave Wall Street a much-needed boost with the Dow and benchmark S&P 500 both ending the day more than 9% higher. “Through talent or through luck, call it whatever you want, but through a very collective action and shared sacrifice, national determination, we will overcome the threat of the virus,” Trump said. Trump said the battered cruise ship industry could expect help. “We will be helping them and we will be helping the airline industry if we have to, assuming we have to,” he said. Trump had been heavily focused on hard-hit industries in making sure the U.S. economy is not devastated by a slowdown in consumer activity as a result of the virus. On Friday, he used much of his appearance to focus on the potential human toll of the respiratory illness than can cause pneumonia in severe cases. He urged every state to set up emergency centers to help fight the coronavirus. “We’ll remove or eliminate every obstacle necessary to deliver our people the care that they need and that they’re entitled to. No resource will be spared, nothing whatsoever,” he said. Pressure has been mounting for Trump to declare an infectious disease emergency under the 1988 law that would allow the Federal Emergency Management Agency (FEMA) to provide disaster funds to state and local governments and to deploy support teams. President Bill Clinton in 2000 employed the rarely used measure to declare such an emergency for West Nile virus. Trump said the federal government was partnering with the private sector to accelerate production of test kits to make them more widely available to Americans. He said there will be about 5 million coronavirus tests available soon but doubted that that many will be needed. He urged Americans to only seek the test if they feel they need it. “We don’t want people to take a test if we feel that they shouldn’t be doing it and we don’t want everyone running out and taking - only if you have certain symptoms,” he said. Alongside Trump was Anthony Fauci, the National Institutes of Health expert who is on Trump’s coronavirus task force. He offered a cautious outlook for what may unfold in the short term. “We still have a long way to go. There will be many more cases. But we’ll take care of that,” said Fauci, long the nation’s top infectious disease expert. “What’s going on here today is going to help it end sooner than it would have.”  Trump said the federal government would waive interest on student loans and ordered the Energy Department to take advantage of low oil prices to top up the Strategic Petroleum Reserve. Claim: Trump declares coronavirus national emergency, says he will most likely be tested.
[EX A]:
U.S. President Donald Trump on Friday declared a national emergency over the fast-spreading coronavirus to free up $50 billion in federal aid and said he would “most likely” be tested for the virus himself soon after facing possible exposure.
