Example Input: The nationwide prevalence of latent tuberculosis infection (LTBI) in Italian patients with psoriasis has never been investigated. To estimate the nationwide prevalence of LTBI in Italian patients with psoriasis who are candidates for systemic treatment. Data were obtained from the Psocare Registry on those patients (n=4946) with age >18years, systemic treatment at entry specified and tuberculin skin test (TST) performed according to the Mantoux method. LTBI diagnosis was based on a positive TST result in the absence of any clinical, radiological or microbiological evidence of active tuberculosis. Latent tuberculosis infection was diagnosed in 83% of patients with psoriasis (409 of 4946). The prevalence of LTBI was lower in patients on biologics than in those on conventional systemic treatments, ranging from 43% (19 of 444) of patients on adalimumab to 31% (eight of 26) of those on psoralen-ultraviolet A (P<005). Independent factors associated with LTBI were male sex [odds ratio (OR) 130, 95% confidence interval (CI) 104-162; P=002], age over 55years (OR 293, 95% CI 218-393; P<0001) and being entered into a conventional treatment (OR 383, 95% CI 310-474; P<0001). Positive history of tuberculosis was seen in 1% of patients (n=49). The nationwide prevalence of LTBI in Italian patients with psoriasis candidate to systemic treatment is high, and screening is recommended prior to biological treatment.
Example Output: The Mantoux test detects what latent infection/disease?

Example Input: Greenwich is on the River, five miles from the middle of London, and its history is two thousand years old. The first English people were fishermen there, and they named the place Greenwich, meaning "green village". Later the English kings and queens lived at Greenwich in their beautiful places. The name of the earliest palace was Placentia. Henry VIII lived there. He knew that England must be strong at sea. So he started two big ship-yards at Greenwich. But trouble was coming to Greenwich. In 1649, a war started in England and for eleven years there was no king. The men who had worked for him at Placentia decided to live the place themselves. They sold all its beautiful things. Finally, the war ended and King Charles II came back. But Placentia was falling down. So King Charles built a new and bigger palace, which is now open to the public. At this time, Charles was worried about losing so many of its ships at sea: their sailors did not know how to tell exactly where they were. So in 1675, Charles made John Flamsteed, the first astronomer in England, try to find the answer. Flamsteed worked in a new building on the high ground in Greenwich Park. From it with a telescope which he made himself, Flamsteed could look all round the sky. And he did, night after night, for twenty years. Carrying on Flamsteed's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea, and helped sailors to know where they were. You can see Harrison's clock, still working, in Greenwich's museum of the sea. Because of Flamsteed's work, every country in the world now tells its time by Greenwich Time.
Example Output: Who made the first clock which could tell the time at sea?

Example Input: Set in the Australian outback in the 1880s, the movie follows the series of events following the horrific rape and murder of the Hopkins family, allegedly committed by the infamous Burns brothers gang.The film opens in a brothel during a violent gunfight between the police and Charlie Burns' (Guy Pearce) gang, which ends with the deaths of all of the gang members except for Charlie and his younger brother Mikey. Captain Stanley (Ray Winstone) proposes to Charlie: he and Mikey can go free of the crimes they have committed if Charlie kills his older brother, Arthur (Danny Huston). Arthur is a mercurial psychopath who has become something of a legend and is so vicious that the Aboriginal tribes refer to him as "The Dog Man" and both the police and the Aboriginals refuse to go near his camp. Captain Stanley muses that perhaps the bounty hunters will kill Arthur in time and then states his intention to civilize the harsh Australian wilderness by bringing Arthur to justice and using Mikey as leverage. Charlie has nine days to find and kill Arthur, or else Mikey will be hanged from the gallows on Christmas Day.We discover why Captain Stanley is intent on taming Australia: he has been forced to move there with his delicate wife, Martha Stanley (Emily Watson), and apparently wants to make it an appropriate place for them to live. The Stanleys were also friends of the Hopkins family, leading Martha to have nightmares about her dead friends and the unborn child one of them is revealed to have carried. Word spreads of Stanley's deal with Charlie, primarily from Stanley's corrupt subordinate, Sergeant Lawrence (Robert Morgan), causing disgust among the townspeople.Shortly thereafter, Eden Fletcher (David Wenham), for whom Captain Stanley works, orders that Mikey be given one hundred lashes as punishment for the rape and murder of the Hopkins family. Stanley is aghast at this, not only because he believes that Mikey is innocent and the flogging will surely kill him, but because it would also break his deal with Charlie and thus put him and his wife in grave danger. Stanley sends Sergeant Lawrence away with tracker Jacko (David Gulpillil) and other men to "investigate" the reported slaying of Dan O'Riley by a group of Aborigines. Captain Stanley attempts to defend Mikey by gunpoint from the bloodthirsty townspeople, but is overruled once Martha arrives, insisting on revenge for her dead friends. Mikey is then brutally flogged, and horrifically wounded. The formerly excited townspeople slowly become disgusted and Martha faints at the ghastly display. After 40 lashes, Mikey has collapsed and the whip is soaked with blood. Captain Stanley grabs the whip and throws it at Fletcher, staining his face and suit with blood, who in turn fires Stanley.Meanwhile, Charlie rides a great distance in search of Arthur, drinking and apparently reflecting on what he will do. Along the way, he encounters an inebriated old man named Jellon Lamb (John Hurt). In the course of conversation, Charlie realizes that Lamb is a bounty hunter in pursuit of the Burns brothers and knocks him out. Later on, after sleeping on a rock bed, Charlie awakes and, before he can gather what's going on, is speared in the chest by a group of Aboriginal men standing over him. Seconds later a gunshot is heard and the head of the man who threw the spear explodes. Charlie then passes out.Charlie wakes up in the camp of his brother Arthur, which is located in caves among desolate mountains. Arthur's gang consists of Samuel Stoat (Tom Budge), who shot the Aboriginal man who had speared Charlie; a woman named Queenie (Leah Purcell) who tends to Charlie's wound; and a muscular Aboriginal man called Two-Bob (Tom E. Lewis). As he recovers from his wounds, Charlie has several opportunities to kill his brother, but does not. Not too far away from Arthur's camp, Sergeant Lawrence and his men have found and butchered a group of Aborigines. Arthur and Two-Bob find Lawrence's group while they sleep, ostensibly to get a horse for Charlie, and proceed to kill Jacko and Sergeant Lawrence. Before Arthur stomps Lawrence
Example Output:
Who plays Samuel Stoat?
