[EX Q]: Paragraph: A day after Australia recorded its hottest day on record, thick smoke blanketed the harbor city, shrouded the Opera House and brought many outdoor activities to a halt. The state of emergency declaration gave firefighters broad powers to control government resources, force evacuations, close roads and shut down utilities across New South Wales, which is home to more than 7 million people. Authorities said nearly 120 fires remained ablaze by late afternoon, more than half of which are uncontrolled, and with temperatures forecast to top 45 degrees Celsius (113°F) in some areas, officials warned residents to be on high alert. “The firefront has been spreading very quickly and intensely,” NSW Rural Fire Service (RFS) Commissioner Shane Fitzsimmons told reporters in Sydney, adding that two firefighters had been airlifted to hospital with burns to their faces and airways. “It’s still a very difficult and dangerous set of circumstances.”  Days out from Christmas, a time when many Australians head to the coast for the holidays, NSW Premier Gladys Berejiklian advised people to make sure “you are prepared to change your plans should circumstances change.”  In Shoalhaven, a popular coastal destination some 190 km (120 miles) south of Sydney, local mayor Amanda Findley said people were poised to evacuate. “There is a large amount of smoke looming over the city, which shows how close the fire is,” Findley told Reuters by telephone. “It is extremely hot and windy now so we are all worried the fire could spread. People are really worried that they may lose everything.”  The RFS posted footage on its official Twitter account showing firefighters tackling one of the three blazes ringing Sydney. A waterbomber aircraft was dwarfed by thick grey and black billowing cloud as it attempted to douse flames in bushland just meters away from homes. Australia has been battling wildfires across much of its east coast for weeks, leaving six people dead, more than 680 homes destroyed and nearly 3 million acres (1.2 million hectares) of bushland burnt. Berejiklian said as many as 40 homes had been destroyed on Thursday. Australia on Wednesday broke all-time heat records for the second day running, with maximum temperatures reaching an average of 41.9 degree Celsius, the Bureau of Meteorology said. Some 1,700 firefighters have been deployed across NSW, but officials warned that was still not enough to cover every potential danger and urged people in high risk areas to evacuate while it was still safe to do so. The current state of emergency will last for seven days, while a total fire ban that has been in place since Tuesday will remain until midnight on Saturday. The major fires around Sydney, which is home to more than 5 million people, have resulted in days of heavy pollution in the city usually known for its sparkling harbor and blue skies. One megafire in the Kanangra Boyd National Park to the city’s southwest had crept to the very outskirts of Campbelltown, a suburb of 157,000 people. By late afternoon, Sydney was sitting at No.4 on the IQAir AirVisual live rankings of pollution in global cities, above Dhaka, Mumbai, Shanghai and Jakarta. Many commuters have donned breathing masks in recent weeks as air quality has plunged to hazardous levels not previously seen in the city. NSW Ambulance Commissioner Dominic Morgan said the service had experienced a 10% surge in call-outs for patients suffering respiratory conditions over the past week and urged susceptible people to remain indoors and keep their medication close. Prime Minister Scott Morrison has weathered a storm of criticism on social media in recent days for going on an overseas holiday during the emergency, adding to criticism that his government is failing to deliver adequate climate change policies. As local media reported Morrison was in Hawaii on a family holiday, about 500 protesters gathered outside his official Sydney residence to demand urgent action on climate change. Morrison’s office refused to confirm his whereabouts. One protestor, wearing an Hawaiian shirt, carried a sign reading, “ScoMo, where the bloody hell are you?” referencing the leader’s nickname and a decade-old international advertisement for Tourism Australia that was banned in several countries because the language was deemed offensive. Australia’s low-lying Pacific neighbors have been particularly critical of the coal-rich nation’s climate policies following modest progress at the U.N. climate talks in Madrid. “It was particularly disappointing to see our Pacific cousins in Australia actively standing in the way of progress at a time when we have been watching in horror as their own country is ablaze,” Marshall Islands president Hilda Heine said in a statement on Wednesday. Claim: Ring of fire: Australian state declares emergency as wildfires approach Sydney.

[EX Q]: Paragraph: The European Medicines Agency had already restricted the use of Protelos - also known as Osseor or strontium ranelate - last April but its pharmacovigilance committee said on Friday the drug should no longer be used to treat osteoporosis at all. The move follows an analysis which found that for every 1,000 patient-years there were four more cases of serious heart problems, including heart attacks, and four more cases of blood clots among patients taking the drug than those on placebo. The recommendation will now be sent to the agency’s Committee for Medicinal Products for Human Use, which is expected to issue a final opinion at its January 20-23 meeting. Claim: EU panel recommends suspension of risky bone disease drug.
[EX A]: European regulators have recommended suspending a popular bone-building drug made by unlisted French firm Servier because of the risk of serious heart problems and blood clots.

[EX Q]: Paragraph: Igor is a 13-year old tiger living in the zoo in the southern Hungarian town of Szeged. It has been suffering from hip joint pains for years. The treatment, used more widely on humans than animals, cures injured joints with tissue taken from patients’ own fatty tissue, which contains regenerative stem cells, doctors said. These are injected back into the ailing joints. “The essence of stem-cell treatment is that we can achieve an improvement in the quality of life of patients who cannot be helped by operations or medical treatment,” said Robert Gippert, the veterinarian who operated on Igor’s hip. “Just like in humans, the worn out joint of Igor the tiger will heal due to the regenerative and self-healing effects of stem cells, without the use of external materials,” he added. The sedated tiger was lying peacefully on its side on the operating table, with its big paws sticking out from below a green blanket. After Igor wakes up, it could take two to three weeks before vets can judge the improvement in its movement. Claim: Igor the Siberian tiger gets stem-cell hip treatment in Hungary.
[EX A]:
Igor, a Siberian tiger in a Hungarian zoo, received stem-cell joint treatment on Wednesday which doctors hoped would help heal its hip and allow it to live happily, on less medicine.
