Generate an appropriate single-sentence summary for the given text such that it includes the main topic of the text.
Example: 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.
Example solution: 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.

Problem: By James CookBBC News, Oklahoma To the red country of Oklahoma a stiff and steady breeze came from the west, stirring the redbud trees and setting their deep purple flowers atremble. It may be spring in the American heartland, but for many teachers here it's not a time of optimism and renewal, but of decay and despair. "I am exhausted constantly," says Chelsea Herndon, a full-time high school biology teacher who also works up to 30 hours a week as a veterinary technician. "I don't know what being well rested feels like anymore," she says, moments after treating a mauled dog. At weekends and on Wednesday nights Ms Herndon toils until 2am at the Animal Emergency Center in Oklahoma City. She has to be back in the classroom at around 7:30am. The children, she says, are being short-changed. "They see their tattered textbooks. They see their tired teachers. They know Thursday mornings Miss Herndon's a little grumpy - she needs some coffee! "So they see it and they want better. They definitely want better." Last year, Oklahoma's education spending per pupil was 28.2% less than it was in 2008, before the Great Recession struck, according to the left-leaning Center on Budget and Policy Priorities. The National Education Association, which represents publicly funded school staff, calls these cuts "the deepest in the nation". Gina Muscari, who teaches second grade at Crutcho Elementary, a rural school outside Oklahoma City, says her students miss what's been cut. "We used to have a really cool art programme," she says, but there's no funding for it. "We used to have choir, all sorts of music… I would love a school nurse. I would love a full time counsellor." They have new textbooks, she says, but "only because we have saved for 10 years". Crutcho is now open four days a week, rather than five, to save money on buses, electricity and support staff. Of the state's 1,820 publicly funded schools, 207 have moved to four-day weeks, according to Christy Watson of the Oklahoma State School Boards Association. And many Oklahoma schools are struggling to retain qualified, talented staff. When one teacher left Crutcho Elementary recently, Muscari and a colleague split the extra pupils between them. "Our kids really, really feel the impact," she says. This crisis follows a decision by the state legislature to sharply reduce taxes in response to the recession, with the aim of encouraging investment and growth. The move was driven by small-government, pro-business Republicans but was also supported by many Democrats. Other states tried the same approach, notably neighbouring Kansas, but few continued cutting as the economy began to improve. Oklahoma was among just a handful of states still reducing school budgets in 2016-17, when funding fell by another 8% over 12 months, second only to Wyoming. Some Oklahoma Republicans now think they went too far. "Any successful society from the Roman Empire [onward] has had to have some form of government," says Leslie Osborn, a Republican member of the state House of Representatives. Osborn says she has changed her mind about the extent to which tax cuts can boost economic growth. She was in favour of the theory that cutting taxes to the bone would spur growth, she says, until the outcomes - "not enough troopers on the road, not enough foster care workers to take care of children, not enough teachers in the classroom" - made her think again. "I've been called a RINO - Republican in Name Only" she says. "I don't believe that's true. I believe that a good Republican can be compassionate, can believe that we need a safety net for people." That's why Osborn strongly supported a move by the state legislature last week to approve modest tax rises on oil and gas production, fuel and cigarettes. The extra revenue will be used to boost school funding and increase teacher pay by an average of $6,100 (£4,340) per year. The bill was signed by Governor Mary Fallin on Thursday, despite opposition from some powerful figures in her party, including former US Senator Tom Coburn, who made a last-minute plea to fellow Republicans. The Oklahoma Oil and Gas Association is also critical, announcing its "firm and complete opposition" to an increase in the production tax paid by the industry - from 2% to 5% - which is still lower than other oil-producing states. "The reality is oversight, efficiency and reducing waste and fraud should be the focus at the Capitol," Association President Chad Warmington said in a statement. Teachers are not satisfied either. The pay rise sounds a lot until you consider the context, says Ms Herndon, the veterinary technician who also heads her school's biology department. She has 10 years of experience as a teacher and makes $33,000. "If I go to Texas I'm starting at almost $50,000 a year. So it's a pretty big difference." Oklahoma is right at the bottom of the barrel for teacher pay in the US, along with West Virginia where striking teachers recently won a 5% rise. Their success stirred disillusioned educators into action here, but also in Arizona and Kentucky. Muscari describes the emergency measures as "a drop in the bucket" after "really deep cuts every single year in education funding for 10 years in a row". A couple of hours drive across the plains from Oklahoma City, she has an ally in Gary Jones, a rancher who is seeking the Republican gubernatorial nomination later this year. Jones is not afraid to style himself as "the only candidate in favour of increasing taxes". He insists he is a dedicated conservative who nonetheless believes that the creed of smaller government and lower taxes can be taken too far. "It's got to be a balance," he says. "It's easy to go out and pander to voters and tell them that I'm going to cut, cut, cut." A desire for efficiency, he argues, must be tempered by the ability to effectively deliver the core services expected from government. That could also be a message for Donald Trump, who is now embarking on a similar course of action at the federal level, albeit with added borrowing thrown into the mix. The president is enormously popular here in Oklahoma, and Republicans are wary of criticising him directly. But Jones and others admit to deep concerns about what the long-term effect on public services will be after slashing taxes and increasing short-term spending and borrowing. Teachers are rather more forthright. "There's days that I'm so angry, I'm disgusted," says Teresa Danks who teaches at an elementary school in Tulsa. "It's embarrassing to say this is what I make. I have a master's degree in education!" She starts work at 5am in front of her home computer, where she tutors students half way across the world, in China. She makes more money per hour doing that, she says, than she does at Grimes Elementary, where she arrives around 7am to begin her second shift of the day. After the school day is over, Danks returns home to work on grading and lessons plans, as well as teaching more online classes. Danks points out that everything in her classroom, except for the furniture, is paid for out of her own salary. She caused a stir last year when she was filmed begging for money for school supplies on a street corner. "We are begging for our voices to be heard as teachers," she tells me. "We're begging for the state of Oklahoma to put education as a priority." Danks is worried other states are following in Oklahoma's footsteps. "Our education system has failed... and it is failing a lot of places across the United States. It is failing our children."

Solution: Teachers in Oklahoma are the latest to walk out of classrooms in protest at sharply cut education budgets. They say what happened to their schools should be a warning for other states.
