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: One official told the Reuters news agency the number who drowned could be more than 200. Rescue efforts have been halted until dawn on Friday. The MV Nyerere ferry overturned near the shore between the islands of Ukora and Bugolora. It is thought the overloaded vessel toppled over when crowds on board moved to one side as it docked. Officials have said the ferry was carrying more than 400 passengers. About 100 people were rescued while 32 are said to be in a critical condition. Exact figures, though, are yet to be confirmed - Reuters said the person who dispensed tickets for the journey also died, with the machine recording the data lost. "We pray to God to give us hope in such an accident," Regional Commissioner Adam Malima told reporters. "We pray to God to give us hope that there has not been a high death toll." Locals joined with emergency teams in rescue efforts on Thursday afternoon. Tragic history Tanzania has seen a number of nautical disasters, with overcrowding often playing a role. In 2012, at least 145 people died when a packed ferry sank while transporting people to the island of Zanzibar in the Indian Ocean. The year before, almost 200 people died in another major incident off the coast of Zanzibar. Hundreds survived, some found clinging to mattresses and fridges. In 1996, more than 800 people died when the MV Bukoba capsized on Lake Victoria. It was one of the the worst ferry disasters of the last century.
A:
At least 42 people have died after a ferry carrying hundreds of people capsized on Lake Victoria, Tanzania.
