Q: By Marianna SpringSpecialist disinformation reporter, BBC News The adverts show the Democratic Party challenger with an earpiece, and say that he refused to have his ears checked for devices prior to the debate. The Biden campaign rejected the claims. The Trump campaign adverts ask: "Why won't Sleepy Joe commit to an ear test?" and "Who is in Joe's ear?" Accusations that presidential candidates have received debate help via hidden hearing devices are familiar, albeit unproven. Such allegations have been levelled against both Republican and Democratic candidates in the past. Prior to Tuesday's debate, the rumour about Mr Biden's supposed earpiece was circulating on several social networks, and was being promoted by the Trump campaign. At least 15 versions The advertising campaign was launched after the debate, and also promotes two other baseless but widely shared rumours about Mr Biden. One suggested he asked for breaks during the debate, and another accused him of refusing a "drug test". The photo featured in the advert is not from Tuesday's debate. It was first shared online in September 2019. In a number of the adverts, it has been doctored to show Mr Biden wearing wireless Apple headphones. This was not the case in the original image. Some versions circle the ear featuring the headphone. By Wednesday evening, there were at least 15 different versions of the advert, and according to Facebook's Ad Library, they had reached at least 10 million users. Facebook has pledged to label posts containing voting misinformation and point users towards accurate information ahead of the election. However its policy does not involve fact-checking political speech, including in advertisements. The company declined to comment about the latest Trump ad campaign. Rumour origins Hours before the debate, the claims went viral on Facebook and YouTube. Identical memes were pushed by a number of popular Facebook pages with names such as US Conservative and Unhinged Left. They claimed "Joe Biden should be inspected for a hidden earpiece as well as submit to a drug test before the debate". These memes are subject to fact-checks - and some have had warning labels applied to them on Facebook. The claims were picked up by Fox News and other conservative news outlets. They were further amplified by supporters of QAnon, an unfounded a conspiracy theory that claims President Trump is fighting a secret war against elite Satan-worshipping paedophiles. Those who believe in QAnon are known for promoting political disinformation on social media which targets opponents of the president. They shared close-up pictures of Mr Biden's ears, alleging a listening device was visible. During the debate, some also shared photos of a fold in Mr Biden's shirt, claiming it was caused by a wire, and of a supposed device on his wrist, where he wears a rosary in memory of his late son Beau. Nothing new Conspiracy theories about secret listening devices have been recycled in presidential election campaigns for the past two decades. Democratic candidate Hillary Clinton faced similar unfounded claims ahead of the 2016 presidential election. In 2004, rumours circulated among left-wing sites and blogs that President George W Bush was being aided by a secret earpiece. None of those allegations were found to be true. Even if a candidate did wear an earpiece, any advantage would be questionable. As TV and radio presenters can attest, listening to someone while simultaneously talking during the back-and-forth of a live event is a difficult skill to master.
A: US President Donald Trump's re-election campaign is running hundreds of Facebook advertisements pushing an unfounded conspiracy theory that Joe Biden cheated during the first US presidential debate.

Q: By Alice CuddyBBC News More than three million people around the world have tested positive for the virus since it first emerged in China late last year. Close to 230,000 have died. There are only a handful of countries that haven't been touched by the pandemic. On Thursday, we told you about the lives of seven people in the UK who died on 12 April, the day the country officially surpassed 10,000 hospital deaths. These are the stories of four other deaths on three continents that also happened that day. Maria Pollidori was admitted to hospital in central Italy in late February for a stomach cancer operation. Everything seemed to have gone smoothly, and her family looked forward to her return. But on 9 April they received a call from the hospital saying the 84 year old had tested positive for coronavirus. Italy has been one of the countries worst-hit by coronavirus. The central region of Marche, where Maria and her family live, has recorded thousands of cases. But Maria's family had no idea that she had been showing any symptoms. Three days after they received the call from the hospital, she passed away. Her son Pierluigi said the hardest thing was not being able to be close to her "at the time she needed us most". Maria's death was not only felt by her family. As a nurse and midwife of 25 years she was well known in and around the small seaside town of Porto Potenza. But because of the pandemic, no-one was able to pay their respects to her at a funeral. It is a story that echoes throughout the country. Thousands of miles away in the US state of Texas, Phillip Tsai-Brooks and his husband Anthony were both in hospital with Covid-19 on 12 April. It was love at first sight when the pair were introduced through mutual friends. They married in 2014 on a cruise ship in San Francisco Bay, and brought Phillip's widowed mother on their honeymoon to Puerto Rico - as they often did on their much-loved international travels. In a statement to the BBC, Phillip's brothers said Phillip and Anthony were able to break barriers, and were accepted as a couple in the city of San Antonio, where they were known for the joy they brought to people's lives. Phillip, one of five brothers, had always dreamed of being a hair stylist and one day opening his own salon. His ambitions were realised when he opened the Extreme Opulence Hair Studio. More recently, he had been teaching others in the profession. Only child Anthony, known as Tony, spent several years in the US Air Force before working for his local council, helping with budget planning for the city of Live Oak. A colleague said he was "smarter about city budgets than most people", and described him as "one of the nicest guys you'll ever meet". The charismatic military veteran would regularly bring sweets into work for the local mayor, dropping them in a jar on her desk, he said. Relatives and friends of the men described them as the perfect couple. They dreamed of one day adopting their own children. But their lives and dreams were tragically interrupted by the outbreak of coronavirus. In a Facebook post in late March, 42-year-old Phillip said he was feeling unwell and had been told to quarantine as a precaution. Six days later, he said he was in hospital with confirmed coronavirus. "Be here for a couple of days… then quarantine," he wrote. Anthony, 52, was taken to a different hospital, suffering similar symptoms. In what Phillip's brothers described as the final chapter of their love story, Tony was moved from another healthcare system into the same hospital as Phillip. As their conditions deteriorated, they lay in rooms next to each other. Phillip passed away on 12 April after suffering a heart attack as a complication of Covid-19. Just two days later, Anthony died. "Such a tragic loss but their love will last forever," Phillip's brothers said. Elsewhere in North America, Victor Batista Falla had recently returned to Cuba, the country of his birth, for the first time in 60 years. The 87 year old was born into one of the wealthiest families in the country, with his father's side founding a bank and his mother descending from rich sugar planters. He fled the country in 1960, after Fidel Castro and his revolutionary forces ousted President Fulgencio Batista. Victor then became a prominent figure of Cuban exile literature, founding the journals Exilio and Escandalar in New York. After moving to Madrid, he opened the publishing house Colibrí, through which he published numerous essays about Cuba. France-based Cuban writer William Navarrete met Victor in the Spanish capital in 1996 at a cafe popular with Cuban exiles. After their first meeting, the pair saw each other whenever William was in Madrid. William described Victor as a man who hated confrontation and gossip, and who was protective of his privacy. "He was a bon vivant, but very measured," William said of his friend. "He never ostentatiously displayed relationships and never boasted about the things he did." Victor's high-profile relationships extended far beyond Cuba. He was the uncle of the Grand Duchess of Luxembourg and a statement from the duke and duchess said his death was a "great loss" for the family. William said Victor never spoke of his connection to the royals and did not like to talk about his family's vast wealth. "Once I asked him if he was nostalgic for the lavish life he had had in Cuba until the age of 27," William recalled. "He replied that he was nostalgic for the things he wanted to do and that he had not done." After 60 years away from the country, Victor quietly returned to Cuba in February. It's not clear what led him to return. William did not know anything of the trip until he read a newspaper article telling him that his friend had died there of Covid-19. In the early hours of 3 December, 1984, a valve broke in a storage tank inside a chemical factory in the central Indian city of Bhopal. Soon after, a deadly cloud of gas escaped from the factory into the surrounding neighbourhoods. It became one of the deadliest industrial disasters in modern history. Thousands of people died, and tens of thousands more needed treatment. Among them was Imran Khan, who was just a young boy when the disaster happened. Two years ago, he developed mouth cancer, believed to be a result of the leak, and had to give up work. After surviving his initial cancer, it returned again, and he was forced to undergo more chemotherapy. His condition deteriorated in recent weeks and he died on 12 April. Later tests confirmed that he had contracted coronavirus. A group representing survivors of the gas tragedy have accused the local government of turning their backs on people like Imran. They say five gas leak survivors died of coronavirus within days of each other. A hospital set up for gas victims was converted into a facility for coronavirus patients. The Bhopal Group for Information and Action says gas victims were then ignored, despite being particularly vulnerable to the virus because of their health conditions. Imran's older brother Rashid Khan is now looking after his wife and son. "The wellbeing of his entire family is on my shoulders," he told BBC Hindi.
