For more than three decades Chum Mey has carried the physical and emotional scars inflicted on him by agents of Cambodia's Khmer Rouge. By Zoe MurphyBBC News He is one of a only handful of people to have survived Tuol Sleng prison, code-named S-21 - the regime's interrogation centre and site of torture and mass murder. Last year, from behind bullet-proof glass in a Phnom Penh courtroom, Chum Mey finally told his story to the world. He was a leading witness in the first trial of a senior Khmer Rouge figure, Kaing Guek Eav, also known as Comrade Duch. Duch was the head of Tuol Sleng, were as many as 17,000 men, women and children were detained and then killed. Chum Mey's testimony to the United Nations-backed court could perhaps help bring them a degree of long-delayed justice. Forced exodus In 1975, Chum Mey - originally from Prey Veng province - was working in Phnom Penh as a mechanic. He was married with three young children. Cambodia at that time was in political turmoil, with the leaders of a 1970 military coup locked in civil war against Pol Pot's forces. On 17 April 1975 the Khmer Rouge captured Phnom Penh. "When they entered everybody including myself raised a white flag to congratulate them; everybody cheered," Chum Mey told the war crimes tribunal. Just hours later, Khmer Rouge representatives went door-to-door telling people to evacuate to the countryside. Chum Mey said those who did not co-operate were shot dead. He gathered his wife and children and joined the exodus. His two-year-old son fell ill and died during the journey. Chum Mey was forced to bury him in a shallow grave and move on. Later, he was sent back to the capital by the Khmer Rouge to repair sewing machines for a co-operative manufacturing the new revolutionary uniform, black pyjamas. On 28 October 1978 he and other workers were told they were being sent to fix vehicles for an offensive against Vietnam. In reality, Chum Mey was about to enter the darkest period of his life, as he was taken to Tuol Sleng. Conspirator There he was imprisoned in a brick cell about two metres by one metre wide, blind-folded and shackled to the floor. For 12 days and nights, Chum Mey says he was tortured, as his interrogators tried to make him confess to spying for the US and Russia. "If you refuse to confess I'll beat you to death. You must tell the truth then I won't kill you. If not I must kill you," he quoted his tormentors as saying. He was whipped repeatedly about the body with a switch of bamboo sticks. When he held up his hands to try to shield himself his fingers were broken. His toenails were pulled out with pliers while his legs were shackled. When he still refused to confess, the nails were twisted and pulled off his other foot. Finally, Chum Mey said he was subjected to electric shocks several times with a wire from a 220-volt wall socket. On each occasion he passed out. When he came round, he was asked again to confess. Eventually he said he confessed to anything so that the torture would be over. In his confession Chum Mey wrote that he was working for the CIA and had recruited dozens of agents in Cambodia. He gave the names of dozens of acquaintances, innocent men and women who, it is presumed, were later arrested, tortured and murdered. "People who had been arrested and killed previously had implicated me, and I implicated others. So did other people. "It was just like rear waves pushing the front waves forward. So people would die one after another, after another, after another," he said in a BBC interview in 2002. Further tragedy Chum Mey believes he was allowed to live because he was of use to the regime, fixing sewing machines in the prison workshop. At night he was chained to a long iron bar with 40 other prisoners. He says they were forced to live in silence. "When I wept I could not make any noise. I wept a lot and I had no more tears to weep, I was only waiting for the day that I would be killed," he later told the war crimes trial. On 7 January 1979, Vietnamese troops captured Phnom Penh from the Khmer Rouge, and the prison staff fled. Chum Mey was marched at gunpoint by prison guards into the provinces, where he had a chance meeting with his wife, and held for the first time his fourth child - a boy, just two months old. For two days they travelled together to an isolated area with a group of other prisoners. They were then ordered to walk into a paddy field, where their captors opened fire on them. The soldiers shot dead his wife and baby. Chum Mey escaped alone and hid in a forest. Justice "I cry every night. Every time I hear people talk about the Khmer Rouge it reminds me of my wife and children," Chum Mey told the public gallery at Duch's trial. He has said that only the court can help to "wash away" his suffering. Last year he was elected as the head of the newly-formed Association of Victims of the Khmer Rouge Regime. Speaking to the BBC just weeks before the verdict, Chum Mey said he hoped Duch would be sentenced to life in prison. But he said he felt cheated by the court, which he said seemed to place most of the responsibility for crimes committed on those perpetrators already dead, rather than focusing on the accused. Although the trial has not brought closure for Cambodians, he told the BBC's Guy De Launey he was satisfied that a judicial system was now in place. Most days Chum Mey can be found at the former prison, which is now a genocide museum, housing the photographs and written confessions of many of the victims. "I come every day to tell the world the truth about the Tuol Sleng prison... so that none of these crimes are ever repeated anywhere in the world."

Imagine that suddenly you cannot recognise your mother, your partner, your child. You can see them but your brain cannot process the information - you don't know whether they are smiling, or understand their emotions. By Gabriela TorresBBC Mundo health reporter That is what happened to David Bromley, after he suffered a brain injury that left him with face blindness. David has prosopagnosia. People with this condition can see the eyes, the nose, and the mouth, what is known as the context - but they cannot see them as a whole. They do not recognise gestures or emotions. "I can even recognise my wife if I walk into the house and know that she is there," says David. "But if I'm in the street and she passes by and I don't know that she is going to be there, I wouldn't recognise her." David, who lives in Essex, had unknowingly been living with eye damage since birth - the arteries and veins were mixed up. This eventually caused a partial loss of sight and damage in the brain which caused the prosopagnosia. Perhaps the most difficult aspect of this condition is that people do not notice right away that something is wrong with them. 'Social embarrassment' He remembers when he realised there was a problem. "I went to a reunion where I saw friends that I hadn't seen for 30 years. We were pretty close but we went our separate ways." On the way home, he told his brother-in-law: "'Fran and Mickey haven't changed a bit, they are exactly the same!'. And then I said 'hold on, were they wearing tank tops?'" What David was seeing was his memory of their friends back then. "My brain was telling me that there they were and what they looked like, but that wasn't the reality". After that, he discovered he was face blind. There are two main forms of prosopagnosia; developmental - where people fail to develop face processing abilities which is thought to affect around 2% of the population, and acquired, which develops after some form of brain injury and is much rarer. Dr Ashok Jansari, a cognitive neuropsychology expert from the University of East London said: "Acquired prosopagnosia is extremely rare because the type of brain damage is very specific,. "It can be caused by damage to the back of the brain on the right-hand side in an area known generally as the right occipito-temporal region." David said: "I don't know what's worse - not being able to ever recognise people or at 56 years old - as it happened to me - suddenly not being able to recognise anybody". He added that the worst part is the social embarrassment. "We were on holiday in Cuba and I'd been snorkelling in the sea. I was talking with this guy from Denmark, when this woman swam up and said 'buenos dias' and I went 'hello, pleased to meet you', thinking it was his wife, but it was actually my wife and I hadn't recognised her." David can see people perfectly well - but 10 or 15 minutes later he cannot recognise them. He now tells clients: "If I ignore you, I'm not being rude, it is just that I can't recognise you." Job fears Sandra, from London, who only wants to give her first name, is also afraid of social embarrassment. She had encephalitis - inflammation of the brain - 14 years ago, which left her with face blindness. Even though her prosopagnosia is mild - she can recognise people she knew before her illness - she would rather not let people know because she does not want anyone to think she has some sort of incapacity. "Life with prosopagnosia is very shameful," she says. She is teacher and at work almost nobody knows that she is face blind. "If I see someone every day, I can recognise them. But if one of the children says hi to me on the street, I would know it is a student from the school, but I wouldn't know who. "I don't say anything to the children, I just work every day to learn their faces." But she says: "Perhaps the reason why I don't mention it is because I don't want them to think that I cannot do my job, because that's not true. I don't want to feel ashamed or that people think that there is something wrong with me." Dr Jansari understands the feelings and fears of David and Sandra. He knows of cases in which people have lost their jobs because of the condition - including a teacher who had difficulty recognising pupils, causing problems when parents came to pick up their children at the end of the day, Even though prosopagnosia is not recognised as a disability, Dr Jansari thinks it should be treated as such in some cases. This condition has no cure. "In the case of acquired prosopagnosia, once a part of the brain is damaged it is not going to 'grow' back, so it is impossible to fix the problem," he said. "With developmental prosopagnosia, we don't know what causes it, but hypothetically in the future if they find that there is a genetic cause, that could be corrected - but that would be a very long way off." Even though people develop strategies to cope - because people change their appearance, they are not foolproof. Dr Jansari says: "Once David thought that a photograph he saw was of George Michael but it was of me, from a time when I used to have a goatee beard and a gold earring!"

I was talking with this guy from Denmark, when this woman swam up and said 'buenos dias' and I went 'hello, pleased to meet you', thinking it was his wife, but it was actually my wife and I hadn't recognised her." David can see people perfectly well - but 10 or 15 minutes later he cannot recognise them. He now tells clients: "If I ignore you, I'm not being rude, it is just that I can't recognise you." Job fears Sandra, from London, who only wants to give her first name, is also afraid of social embarrassment. She had encephalitis - inflammation of the brain - 14 years ago, which left her with face blindness. Even though her prosopagnosia is mild - she can recognise people she knew before her illness - she would rather not let people know because she does not want anyone to think she has some sort of incapacity. "Life with prosopagnosia is very shameful," she says. She is teacher and at work almost nobody knows that she is face blind. "If I see someone every day, I can recognise them. But if one of the children says hi to me on the street, I would know it is a student from the school, but I wouldn't know who. "I don't say anything to the children, I just work every day to learn their faces." But she says: "Perhaps the reason why I don't mention it is because I don't want them to think that I cannot do my job, because that's not true. I don't want to feel ashamed or that people think that there is something wrong with me." Dr Jansari understands the feelings and fears of David and Sandra. He knows of cases in which people have lost their jobs because of the condition - including a teacher who had difficulty recognising pupils, causing problems when parents came to pick up their children at the end of the day, Even though prosopagnosia is not recognised as a disability, Dr Jansari thinks it should be treated as such in some cases. This condition has no cure. "In the case of acquired prosopagnosia, once a part of the brain is damaged it is not going to 'grow' back, so it is impossible to fix the problem," he said. "With developmental prosopagnosia, we don't know what causes it, but hypothetically in the future if they find that there is a genetic cause, that could be corrected - but that would be a very long way off." Even though people develop strategies to cope - because people change their appearance, they are not foolproof. Dr Jansari says: "Once David thought that a photograph he saw was of George Michael but it was of me, from a time when I used to have a goatee beard and a gold earring!"

Imagine that suddenly you cannot recognise your mother, your partner, your child. You can see them but your brain cannot process the information - you don't know whether they are smiling, or understand their emotions. By Gabriela TorresBBC Mundo health reporter That is what happened to David Bromley, after he suffered a brain injury that left him with face blindness. David has prosopagnosia. People with this condition can see the eyes, the nose, and the mouth, what is known as the context - but they cannot see them as a whole. They do not recognise gestures or emotions. "I can even recognise my wife if I walk into the house and know that she is there," says David. "But if I'm in the street and she passes by and I don't know that she is going to be there, I wouldn't recognise her." David, who lives in Essex, had unknowingly been living with eye damage since birth - the arteries and veins were mixed up. This eventually caused a partial loss of sight and damage in the brain which caused the prosopagnosia. Perhaps the most difficult aspect of this condition is that people do not notice right away that something is wrong with them. 'Social embarrassment' He remembers when he realised there was a problem. "I went to a reunion where I saw friends that I hadn't seen for 30 years. We were pretty close but we went our separate ways." On the way home, he told his brother-in-law: "'Fran and Mickey haven't changed a bit, they are exactly the same!'. And then I said 'hold on, were they wearing tank tops?'" What David was seeing was his memory of their friends back then. "My brain was telling me that there they were and what they looked like, but that wasn't the reality". After that, he discovered he was face blind. There are two main forms of prosopagnosia; developmental - where people fail to develop face processing abilities which is thought to affect around 2% of the population, and acquired, which develops after some form of brain injury and is much rarer. Dr Ashok Jansari, a cognitive neuropsychology expert from the University of East London said: "Acquired prosopagnosia is extremely rare because the type of brain damage is very specific,. "It can be caused by damage to the back of the brain on the right-hand side in an area known generally as the right occipito-temporal region." David said: "I don't know what's worse - not being able to ever recognise people or at 56 years old - as it happened to me - suddenly not being able to recognise anybody". He added that the worst part is the social embarrassment. "We were on holiday in Cuba and I'd been snorkelling in the sea.

I was talking with this guy from Denmark, when this woman swam up and said 'buenos dias' and I went 'hello, pleased to meet you', thinking it was his wife, but it was actually my wife and I hadn't recognised her." David can see people perfectly well - but 10 or 15 minutes later he cannot recognise them. He now tells clients: "If I ignore you, I'm not being rude, it is just that I can't recognise you." Job fears Sandra, from London, who only wants to give her first name, is also afraid of social embarrassment. She had encephalitis - inflammation of the brain - 14 years ago, which left her with face blindness. Even though her prosopagnosia is mild - she can recognise people she knew before her illness - she would rather not let people know because she does not want anyone to think she has some sort of incapacity. "Life with prosopagnosia is very shameful," she says. She is teacher and at work almost nobody knows that she is face blind. "If I see someone every day, I can recognise them. But if one of the children says hi to me on the street, I would know it is a student from the school, but I wouldn't know who. "I don't say anything to the children, I just work every day to learn their faces." But she says: "Perhaps the reason why I don't mention it is because I don't want them to think that I cannot do my job, because that's not true. I don't want to feel ashamed or that people think that there is something wrong with me." Dr Jansari understands the feelings and fears of David and Sandra. He knows of cases in which people have lost their jobs because of the condition - including a teacher who had difficulty recognising pupils, causing problems when parents came to pick up their children at the end of the day, Even though prosopagnosia is not recognised as a disability, Dr Jansari thinks it should be treated as such in some cases. This condition has no cure. "In the case of acquired prosopagnosia, once a part of the brain is damaged it is not going to 'grow' back, so it is impossible to fix the problem," he said. "With developmental prosopagnosia, we don't know what causes it, but hypothetically in the future if they find that there is a genetic cause, that could be corrected - but that would be a very long way off." Even though people develop strategies to cope - because people change their appearance, they are not foolproof. Dr Jansari says: "Once David thought that a photograph he saw was of George Michael but it was of me, from a time when I used to have a goatee beard and a gold earring!"

Here is an summary requirement:

The article features two individuals, David Bromley and Sandra, who suffer from prosopagnosia, a condition that impairs their ability to recognize faces. David developed the condition after suffering a brain injury, while Sandra acquired it after encephalitis. Both individuals experience social embarrassment and fear losing their jobs due to their condition. David is a client who warns people that he may not recognize them, while Sandra is a teacher who works hard to learn her students' faces.

David Bromley is a man from Essex who suffers from prosopagnosia, or face blindness, after a brain injury. He struggles with recognizing people, including his wife, and experiences social embarrassment due to his condition. Sandra, a teacher from London, also has face blindness as a result of encephalitis. She can recognize people she knew before her illness but struggles with new faces and fears social embarrassment and job loss. Dr. Ashok Jansari is a cognitive neuropsychology expert from the University of East London who discusses the rarity of acquired prosopagnosia and the challenges faced by those with the condition.


You are a helpful assistant in evaluating the quality of the outputs for a given instruction. Your goal is to select the best output for the given instruction.

Select the Output (a) or Output (b) that is better for the given instruction. The two outputs are generated by two different AI chatbots respectively.

Here are some rules of the evaluation:
(1) You should prioritize evaluating whether the output honestly/precisely/closely executes the instruction, then consider its helpfulness, accuracy, level of detail, harmlessness, etc.
(2) Outputs should NOT contain more/less than what the instruction asks for, as such outputs do NOT precisely execute the instruction.
(3) You should avoid any potential bias and your judgment should be as objective as possible. For example, the order in which the outputs were presented should NOT affect your judgment, as Output (a) and Output (b) are **equally likely** to be the better.

Do NOT provide any explanation for your choice.
Do NOT say both / neither are good.
You should answer using ONLY "Output (a)" or "Output (b)". Do NOT output any other words.

Imagine that suddenly you cannot recognise your mother, your partner, your child. You can see them but your brain cannot process the information - you don't know whether they are smiling, or understand their emotions. By Gabriela TorresBBC Mundo health reporter That is what happened to David Bromley, after he suffered a brain injury that left him with face blindness. David has prosopagnosia. People with this condition can see the eyes, the nose, and the mouth, what is known as the context - but they cannot see them as a whole. They do not recognise gestures or emotions. "I can even recognise my wife if I walk into the house and know that she is there," says David. "But if I'm in the street and she passes by and I don't know that she is going to be there, I wouldn't recognise her." David, who lives in Essex, had unknowingly been living with eye damage since birth - the arteries and veins were mixed up. This eventually caused a partial loss of sight and damage in the brain which caused the prosopagnosia. Perhaps the most difficult aspect of this condition is that people do not notice right away that something is wrong with them. 'Social embarrassment' He remembers when he realised there was a problem. "I went to a reunion where I saw friends that I hadn't seen for 30 years. We were pretty close but we went our separate ways." On the way home, he told his brother-in-law: "'Fran and Mickey haven't changed a bit, they are exactly the same!'. And then I said 'hold on, were they wearing tank tops?'" What David was seeing was his memory of their friends back then. "My brain was telling me that there they were and what they looked like, but that wasn't the reality". After that, he discovered he was face blind. There are two main forms of prosopagnosia; developmental - where people fail to develop face processing abilities which is thought to affect around 2% of the population, and acquired, which develops after some form of brain injury and is much rarer. Dr Ashok Jansari, a cognitive neuropsychology expert from the University of East London said: "Acquired prosopagnosia is extremely rare because the type of brain damage is very specific,. "It can be caused by damage to the back of the brain on the right-hand side in an area known generally as the right occipito-temporal region." David said: "I don't know what's worse - not being able to ever recognise people or at 56 years old - as it happened to me - suddenly not being able to recognise anybody". He added that the worst part is the social embarrassment. "We were on holiday in Cuba and I'd been snorkelling in the sea.
