PROBLEM: Paragraph: Central to the plan to protect the city, some or all of the 78 barriers will one day be raised when the sea rises more than 110 centimeters (43 inches), to prevent damaging high tides from pushing into the lagoon city, a world heritage site built picturesquely — but somewhat precariously — upon more than 120 islands. Concerns that high tides are becoming more frequent because of climate change have increased the urgency. While the concept is simple, its realization has been anything but. The system of movable underwater barriers, dubbed Moses, has been beset by corruption, cost overruns and delays. Projected at 1.8 billion euros ($2 billion) and meant to be completed by 2011, the project has so far cost 5.5 billion euros and is running a decade behind schedule. In the wake of last month’s flooding of Venice, the worst in 53 years, the consortium that oversees construction of Moses is eager to demonstrate that the project — after years of bad news — is on track and will be fully operational by the end of 2021. Venetians say they cannot afford to be wrong. Skeptics and critics say they may be. A recent test of the deepest expanse of barriers — at the Malamocco entrance to the lagoon — was declared a success by the New Venice Consortium. It was the last of the four sections of barriers to be completely raised — but so far only in calm seas. The real test will come when all four are raised at once, and not only in serene waters, but under flood conditions. That isn’t scheduled to take place until the end of next year. It took six years to test each of the four movable sea walls covering the three openings to the lagoon, partly because work was slowed by a 2014 corruption scandal that implicated the three main contractors and sent 35 people to jail. Work is continuing largely with the original subcontractors now contracting directly with the consortium, which itself has been placed under government control as a result of the scandal. The fact that the barriers have not yet been physically tested in rough seas is a concern to critics. Paolo Vielmo, an offshore marine engineer who has long criticized the project, said that tests carried out in a laboratory in the Netherlands in the 1990s indicated that the barriers, under certain conditions, would oscillate out of control — possibly even breaking apart. “Its behavior is not predictable,’’ Vielmo said. He said that the trials so far declared successful have been under only modest sea conditions that fail to represent anywhere near the threat of the phenomenon of extreme oscillation called subharmonic resonance. Vielmo and two other offshore engineers have compiled a report for the Codacons consumer and environment protection advocacy group, which is asking officials to run additional calculations to see if the project is indeed viable. And if it is not, Codacons says Moses should be stopped. “We don’t want to delay by one minute the possibility to make Moses operational. But we say we cannot make it operational until we are sure it will work,’’ said Franco Conte, president of Codacons in Venice. “Naturally, the Venetian community is exasperated and they say, ‘If we did 95%, let’s do 100% and see if that works.’ But that is unconscionable. If we don’t know if it works, we cannot experiment.”  The barrier system is made up of giant flood gates, each 20 meters (66 feet) long. The gates are attached by hinges to giant cement blocks placed on the seabed along the three openings from the sea into the lagoon, Malamocco, Chioggia and the Lido. The gates can be lifted to create a temporary barrier in high tides. Once the water has receded, they can be lowered again — allowing shipping traffic to continue and for the tidal system to flush out the lagoon. The idea behind the project was to create a mobile system that would not impede views of the unique and protected landscape. But Moses has suffered criticism from the start that there were simpler, cheaper systems that could have been deployed. Venetians have been waiting since the record 1.94-meter (6.36-foot) flood of 1966 for a system to protect them from regular inundations. The flooding in November, the second-worst recorded, proved the urgency. In the 150 years that they have been recording the tide levels in Venice, two high tides above 1.5 meters have never been recorded in a year. In November, there were three in one week. Climate scientists note that exceptional tides — those over 1.4 meters — have become much more frequent in the past two decades, with more than half of all recorded occurring since 2000. “One has to realize the kind of existential question that that serious flooding has given rise to,” said Jane Da Mosto, an environmental scientist and executive director of the non-profit group We Are Here Venice, which is working to defend the city against myriad issues, including depopulation, cruise traffic through St. Mark’s basin and overtourism. “People are asking: will Venice be defendable against these kinds of episodes?’’  It’s not just the still-uncalculated damage to landmarks like St. Mark’s Basilica, where corrosive salt water creeps through porous brick and tile. It’s also the boxes of ruined belongings and piles of soaked mattresses discarded in alleyways and loaded onto motorboats and trash barges for disposal. The relentlessness of the Venetian fall and winter tides make one-third of ground floors uninhabitable in the historic canal city. “I am very old, I cannot say that I want to die, but I certainly do not want to be witness to the fact that it does not work,” 84-year-old resident Paola Scarpa said of the Moses barriers, as she walked to check on a family property in the Canareggio neighborhood on a recent December morning. “It would be a pain too great.”  ___  Associated Press journalist Trisha Thomas contributed to this report. Claim: Venice tide barriers pass another test but skeptics remain.

SOLUTION: Floated along by barge , one of the 10-ton barriers designed to relieve Venice’s perennial flooding looks like a giant plaything: an oversized hinged yellow Lego.

PROBLEM: Paragraph: After a spate of mass shootings in early August 2019 in the United States, gun violence once again became a major topic of political debate in the country, and many expressed their views on potential solutions to the problem. The left-leaning Facebook page Occupy Democrats suggested that tighter gun-ownership regulations could help to reduce levels of firearms-related fatalities. On Aug. 7, the page posted a meme that claimed: “In Massachusetts, to buy a gun you have to take a four-hour gun safety course, get character references from two people, and have a one-on-one interview with a police officer. Oh, and it has the lowest gun death rate in America. Let’s do this everywhere.”    We received inquiries from readers about the accuracy of that two-part claim. On the whole, the Occupy Democrats meme had a high degree of accuracy. Elements of the meme appeared to have been copied from a Facebook post earlier on Aug. 7 by U.S. Sen. Edward Markey, D-Mass. The meme itself was accompanied by text that read:  “‘Adjusted for age and population, the gun fatality rate in Massachusetts for 2016 was the lowest in the U.S. And that’s how it’s been for most of the last 30 years, although sometimes another state, like Hawaii, which also has very strict gun laws, ends up with a slightly lower rate. '” That text is actually a quotation taken from a May 6, 2018, article published by the Huffington Post, which went on to provide the following disclaimer: “Just how much that low rate has to do with the state’s gun laws is a matter of ongoing debate, even among experts. Pretty much any legitimate study is going to rely on assumptions that will be open to valid criticism; separating out cause and effect can be virtually impossible. But the available research provides a good reason to think Massachusetts laws in general and the permit system in particular have made violence less likely.” This fact check won’t attempt to rule on the validity of any claim that relatively strict gun regulations in Massachusetts are the primary or exclusive cause of that state’s purportedly low rate of firearms-related deaths, merely whether both factors are present there. Massachusetts state law certainly contains comparatively stringent requirements for obtaining and renewing firearms licenses, as well as purchasing and carrying firearms, and the claims made in the Occupy Democrats meme were largely accurate. In Massachusetts, anyone who wishes to purchase or carry a firearm must obtain a firearms license, of which there are two kinds: a license to carry and a firearms identification card (FID), the latter of which relates to rifles and shotguns. Applications for firearms licenses are processed by local police forces, and a 2014 state law gave law-enforcement agencies relatively wide authority and discretion to deny license applications, through a court process, where a license applicant poses a demonstrable risk to public safety. All first-time applicants for a license to carry or an FID must complete a one-day MA Certified Firearms Safety Course or a Basic Hunter Education Course, as part of the application. So the meme’s claim is accurate as regards first-time license applicants, but not for those who already have one, who are not required to undergo training every time they wish to purchase a new gun, for example. Furthermore, all applicants (whether first-time applicants or those applying to renew their firearms license) must provide two character references, as outlined in the state-issued “LTC/FID/Machine gun application,” which can be viewed here. The meme is accurate in this regard. Finally, Massachusetts state law does not oblige a “licensing authority” (typically a police force) to require an in-person interview with license applicants, but many police forces, including the largest in the state, Boston’s, do require such an interview. So that obligation is not prescribed in law, but is a practical necessity for many firearms-license applicants, which partially vindicates the meme’s claim in this regard. This was true in 2016, as the Huffington Post article (which Occupy Democrats indirectly cited as its source) outlined, though not quite accurate in 2017. The Centers for Disease Control and Prevention (CDC) tracks gun deaths (along with many other cause of death) in each state every year. The CDC also calculates gun death rates in each state every year — that is, the number of firearms-related deaths per 100,000 people living in the state, after taking into account and standardizing age distributions across states. In its standard measure of gun deaths, the CDC counts all forms of firearms fatalities including homicides, suicides and accidental discharges. In 2016, Massachusetts had the lowest age-adjusted gun death rate in the country, with 3.4 fatalities per 100,000 people. Rhode Island, New York, Hawaii and Connecticut had the next-lowest death rates, while Alaska, Alabama and Louisiana had the highest rates of gun deaths in the U.S., with 23.3, 21.5 and 21.3 fatalities per 100,000 people, respectively:  Along with New York, Massachusetts had the joint second-lowest gun death rate in 2017, with 3.7 per 100,000 people, behind Hawaii, which had 2.5 such fatalities per 100,000 people:  As the Huffington Post article pointed out, Massachusetts regularly has among the lowest annual rates of gun deaths in the United States. As well as in 2016, it also had the lowest rate in 1999, 2000, 2001, 2009, 2012 and 2015,  The chart below shows the age-adjusted gun death rate of every state, taking into account all gun deaths between 1999 and 2017. Massachusetts had the second-lowest gun death rate over that 19-year period, behind Hawaii. Louisiana, Alaska, the District of Columbia and Mississippi had the highest:  Although the Occupy Democrats Facebook post clearly specified that the basis of the claim in the meme were the figures for 2016, a year in which Massachusetts did indeed have the lowest gun death rate in the country, the meme itself did not make that clear. Taken on its face, the meme was claiming that Massachusetts had the lowest rate of gun deaths in either 2019 (the year in which it was posted) or 2018 (the most recent full year). The state may well ultimately be shown to have the lowest rate of gun deaths in the country during those years, but CDC data for 2019 and 2018 will not be available until 2021 and 2020, respectively. On the whole, the Occupy Democrats meme was highly accurate, though not perfectly so. Claim: Massachusetts has certain strict gun-ownership requirements and the lowest rate of gun deaths in the United States. 

SOLUTION: What's true: Massachusetts requires gun-license applicants to provide character references; first-time applicants must complete a one-day safety training course; and many police departments require an in-person interview before approving license applications. Massachusetts regularly has either the lowest or second-lowest rate of gun deaths in the United States. What's false: In 2017, the most recent year for which data is available, Massachusetts had the second-lowest rate of gun deaths, but data for 2018 and 2019 are not yet available. The gun-license requirements set out in the meme do not necessarily apply to all applicants.

PROBLEM: Paragraph: A few weeks later, all three children were dead, victims of the worst measles outbreak on the Indian Ocean island in decades. Measles cases are on the rise globally, including in wealthy nations such as the United States and Germany, where some parents shun life-saving vaccines due to false theories suggesting links between childhood immunizations and autism. In Madagascar, one of the world’s poorest countries, parents are desperate to vaccinate their children, many trudging for miles to get to clinics for shots. But there are not enough vaccines, the health ministry says, and many people are too poor to afford them. Fisherman Dada – like many Malagasy, he only uses one name – had taken his son Limberaza to be vaccinated once already in their home in the southern district of Fort Dauphin. But a second-dose booster shot cost $15 at a clinic - and the whole family survives on less than $2 a day - so he took the boy to a back-street doctor instead. “I could not afford to take him to the hospital,” Dada said quietly as his young wife silently held Limberaza’s two-year-old brother. In January, Limberaza began to cough. A rash followed. After a week, he died, his body afire with fever. By then Dada’s niece, three-year-old Martina, was also sick. Her weeping mother Martine stroked her face as her fever spiked. She died eight days later. That evening, his other sister Pela’s three-year-old son Mario died as she clutched his hands. “They were so full of life,” Dada said, his voice breaking. The three cousins are among the almost 1,000 people, mostly children, who have died from measles in Madagascar since October. Their deaths show the grim reality for those left unprotected from one of the world’s most contagious diseases. The virus, which can cause blindness, pneumonia, brain swelling and death, is able to survive for up to two hours in the air after a cough or sneeze, where it can easily infect people nearby. Even though there is a highly effective vaccine, globally, around 110,000 people died from measles in 2017, according to the World Health Organization (WHO). Most, like Limberaza and his cousins, were children under the age of five. During 2000 to 2017, the WHO estimates that widespread use of measles vaccinations prevented 21.1 million deaths - making the shots one of what the United Nations’ health agency calls the “best buys in public health.”  Yet misinformation is knocking confidence in the safety of vaccinations and has jeopardized progress against measles - allowing the disease to gain a hold again in places where it was considered almost beaten. Europe last year saw its highest level of measles cases in a decade, and in January, the WHO named “vaccine hesitancy” - the reluctance or refusal to vaccinate - as one of the top ten global health threats for 2019. In Madagascar, poverty is a bigger risk. While wealthy tourists flock to its rainforests to spot wide-eyed lemurs and business people bargain for its luminous sapphires and fragrant vanilla, nearly half of Madagascar’s children are malnourished, the highest rate in Africa. The former French colony has been battered by decades of coups and instability. Foreign aid plummeted after a 2009 coup sparked bitter political street fighting. Corrupt leaders ignored the crumbling healthcare system despite frequent outbreaks of plague, hemorrhagic fevers and deadly viruses. Measles is endemic on the island but the last vaccination drive was in 2004. Nearly two-thirds of children have not been vaccinated, according to the WHO and coverage needs to be around 95 percent to prevent the virus spreading in communities. The country is $3 million short of the $7 million needed for enough measles vaccines to cover its population, the WHO said last month. There are other hurdles. The vaccines must be kept cold, but less than 15 percent of people in Madagascar have electricity. Roads are mostly mud in the tropical country; journeys are arduous and expensive. At least 922 people - mostly children - have died of measles in Madagascar since October, the WHO says, despite an emergency program that has vaccinated 2.2 million of the 26 million population so far. Some of those, like Limberaza, had previously been vaccinated but had only received one shot, and still needed a second booster jab. Madagascar hopes to roll out a free routine two-dose vaccination program this year. Currently, the first shot is free but the booster is not. Despite the difficulties, some parents walk miles seeking shots, said Jean Benoît Mahnes, deputy representative for the United Nations Children’s Fund in Madagascar. But they often arrive to find the clinic closed, or a doctor with no vaccine, or a vaccine that has expired. “Vaccinating a child can be a real obstacle course here,” he said. Lydia Rahariseheno, 33, said she had to walk an hour and a half to a clinic along a road plagued by robbers to get her three children vaccinated. She has only managed to get one shot so far because the doctor is often not there. The health system’s failures mean poverty-stricken parents often take sick children to traditional healers who prescribe a herb, tingotingo, which is boiled and given to them to drink. The children are only brought to a hospital when their condition deteriorates, said Manitra Rakotoarivony, director of health promotion at the Ministry of Public Health. Limberaza’s father hoped a second, cheaper shot would protect him - but it didn’t. His cousins Mario and Martine weren’t vaccinated at all. Now the family is desperate to protect their remaining children. “We did not expect the failure to vaccinate him would kill him,” wept Pela, Mario’s mother. “My other child, for sure, I am going to take him to get vaccinated.” Claim: Without vaccine, hundreds of children die in Madagascar measles outbreak.

SOLUTION:
Two months ago, giggles floated through the home of fisherman Dada as his four-year-old son played ball outside with his two younger cousins on one of Madagascar’s famed sun soaked beaches.
