question:
Paragraph: In December 2016, a video went viral, purportedly showing a man punching a kangaroo in order to save a dog:  Matthew Amor, who organized the trip in support of a friend who was battling an incurable disease, detailed the events that led to his friend punching a kangaroo to News.com.au: Mr Amor said it was totally out of character for his friend, Mr Tonkins, to hit the marsupial, describing him as a “placid bloke”. “My mate has a good government job, so he’s gone pretty quiet on this,” Mr Amor laughed. “We were driving along, the dogs are loose. They are trained to smell pig’s blood, and picked up a scent. “The dogs went past 20 kangaroos, which they are trained not to touch. “Anyway, this big buck got a hold of my friend’s dog. It just grabbed him.” Shortly after the video went viral, many people called on Taronga’s Western Plains zoo to fire Tonkins for punching the kangaroo. However, the zoo released a statement on 6 December 2016, saying that the incident did not put Tonkins’ position in jeopardy: Best practice animal welfare and the protection of Australian wildlife are of the utmost importance to Taronga. Taronga strongly opposes the striking of animals and does not support the practice of using dogs to hunt, as this can result in negative welfare for both species. We support the Guidelines outlined by the Department of Environment and Heritage in the event of confrontation with a kangaroo. Mr Tonkins is an experienced Zoo keeper and during his six years at Taronga Western Plains Zoo has always followed Taronga’s best practice approach to animal care and welfare. We confirm that there is no suggestion of Mr Tonkins’ employment at Taronga Western Plains Zoo ending as a result of this event. However, the highest standards of animal welfare and care are a core value of Taronga and one that we expect our staff to uphold in all their interactions with wildlife and we continue to work with Mr Tonkins on his conduct in regards to this incident. Kangaroos are often portrayed as cuddly and gentle marsupials and are generally docile, but can be quite vicious and even dangerous (kicking with their muscular back legs, using feet topped by razor-sharp nails as weapons) when they feel threatened (often by dogs). Claim: A viral video shows a man punching a kangaroo in the face to save his dog.
answer:
In this case, though, all parties — dog, man, and kangaroo — emerged from the confrontation relatively unscathed.


question:
Paragraph: "Ed Stafford of Leicestershire, England walks in between trees as he walks through the Amazon jungle in Brazil in this undated handout photo. Former British army captain Stafford became on Monday the first known person to walk from the origin of the Amazon river, the world's second-longest river, to its mouth, after withstanding ""50,000"" mosquito bites, scorpion attacks and skin disease in his 859 day odyssey. REUTERS/Handout Ed Stafford, a 34-year-old from Leicestershire, England, dived into the Atlantic Ocean after taking 859 days to walk the length of the world’s second-longest river, starting at the peak of Mount Mismi in Peru in April 2008. “It’s just phenomenal to be here at the end of the journey after 2-1/2 years slogging our way through the jungle,” he told Reuters after arriving at the beach about 90 miles northeast of the Brazilian city of Belem. “It was really difficult to envisage how this was going to feel and I’m completely overwhelmed.”   Stafford briefly collapsed from exhaustion with only 52 miles of the 6,000-mile journey to go, passing out by the roadside after breaking out in a rash. “I feel slightly humbled that my system just decided to shut down so close to the finish,” he wrote on his blog at www.walkingtheamazon.com. Stafford has aimed to use the walk to raise awareness about the threats to the Amazon rain forest and its people, using a portable satellite video to blog about his trek. He had planned to complete the walk in about a year, but the journey was prolonged by floods that forced him to walk a roundabout route that was 2,000 miles longer than the 4,000-mile (6,400-km) length of the Amazon, which is exceeded in length only by Africa’s Nile river. He began the journey with fellow British adventurer Luke Collyer, but the pair had a falling out early in the trek and Stafford continued alone. He was joined in July 2008 by a Peruvian forestry worker, Gadiel Cho Sanchez Rivera, who pledged to walk with him for five days and has been with him on the walk ever since. A statement from Stafford’s media team said that the Briton had been: “wrongly accused of murder on two separate occasions, been imprisoned, had concrete stuffed in his mouth by hostile tribes people, been chased by Ashaninka Indians with bows and arrows, been stung by hundreds of wasps and watched as his guide ‘Cho’ removed a botfly from Ed’s head with superglue and a tree spine.”   It said he had endured “50,000” mosquito bites, lived on a diet of piranha fish, rice and beans, and dodged a variety of snakes, electric eels, scorpions, and ants, as well as contracting a skin-disfiguring disease. Famed British explorer Sir Ranulph Fiennes was quoted as saying in the statement that Stafford’s feat was “truly extraordinary.”   “No one has ever done this before and the pundits considered the route impossible,” he said." Claim: British man becomes first to walk Amazon length.
answer:
A former British army captain became on Monday the first known person to walk from the origin of the Amazon river to its mouth, after enduring “50,000” mosquito bites, attacks by hostile Indians and tropical disease in his nearly 2-1/2 year odyssey.


question:
Paragraph: The heavier the infection, the more likely the women were to deliver younger, sicker infants, the team at Stanford University in California found. “If we could prevent these infections in the first place, or detect them sooner, we might one day be able to prevent some of these premature births,” Dr. Dan DiGiulio, who worked on the study, said in a statement. More and more children are being born prematurely in the United States, with 12 percent of births coming before the 37th week of gestation. Premature babies are vulnerable to breathing problems, underdeveloped organs, infections and cerebral palsy. DiGiulio’s team looked for the DNA of germs in amniotic fluid samples collected from 166 women in pre-term labor at the Detroit Medical Center between October 1998 and December 2002. They used this method and standard laboratory cultures to determine that 25 of the 166 samples were infected with either bacteria or fungi. They also found at least one unknown organism that could be a new species. All 25 of the women with infected amniotic fluid went on to deliver their babies pre-term, while 53 of the women with no infections were able to stop their labor. Now the team is working to see if infections can be detected before pre-term labor starts, which could lead to new prevention or treatment approaches. Claim: Infections may cause many premature births: study.
answer:

Undiagnosed infections may be causing a significant number of premature births, researchers reported on Monday after finding bacteria or fungi in 15 percent of the amniotic fluid samples taken from women in pre-term labor.
