In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: Dr. Edwards arrives at a secluded island laboratory to examine Mr. Porter. Although Porter carries a deadly flesh-eating virus, he is asymptomatic and shows no signs of necrosis. Along with fellow researchers Camila and Bridget, Dr. Edwards spends two months examining Porter in isolation. Porter continually asks to see his wife, but he is continually denied.
Marcus prepares to marry wealthy heiress Kate Arias in the Dominican Republic. Mark's best friend Dobs, his brother Josh, and Josh's girlfriend Penny charter a boat and take Mark to a supposedly unpopulated island for a low key bachelor party.
Sympathetic researcher Camila creates a rapport with Porter. Frustrated with his confinement, Porter intentionally infects one of the researchers as he begins revolting against his continued isolation. Porter warns Camila that he is dangerous. Bridget becomes infected.
Josh and Penny go snorkeling and find dead sea animals littering the ocean floor. When they return to camp, Josh and Penny discover strange rashes on their skin. While Josh performs oral sex on her, Penny begins spitting up large amounts of blood and her flesh starts melting. Josh radios for help and a voice claiming to be Dr. Edwards provides him with instructions.
Realizing that they need help but are stranded, Mark and Dobs search the island and find a bunker. Inside, the two friends discover research related to the virus. They also find mutated men who attempt to kill them. Mark and Dobs are able to escape the human danger, but Dobs becomes infected.
The bunker turns out to be connected to Dr. Edwards' laboratory. Josh reunites with Mark and Dobs and they find the researchers. After formulating a plan for extraction, Bridget and Josh split off to gather Penny and wait for the boat on the beach. Dobs and Edwards also go on their own while Porter, Camila, and Marcus initiate the laboratory's self-destruct sequence. 
Question: Who discovers research related to a virus?
Example Output: Mark.

Example Input: Passage: At a London music hall theatre, Richard Hannay is watching a demonstration of the superlative powers of recall of "Mr. Memory" (Wylie Watson) when shots are fired. In the ensuing panic, Hannay finds himself holding a seemingly frightened Annabella Smith, who talks him into taking her back to his flat. There, she tells him that she is a spy, being chased by assassins, and that she has uncovered a plot to steal vital British military information, masterminded by a man with the top joint missing from one of his fingers. She mentions the "39 Steps", but does not explain its meaning.
Later that night Smith, fatally stabbed, bursts into Hannay's bedroom and warns him to flee. He finds a map of the Scottish Highlands clutched in her hand, showing the area around Killin, with a house or farm named "Alt-na-Shellach" circled. He sneaks out of his flat disguised as a milkman to avoid the assassins waiting outside. He then boards the Flying Scotsman express train to Scotland. He learns from a newspaper article (read by a pair of women's undergarment salesmen) that he is the target of a nationwide manhunt for Smith's murder. When he sees the police searching the train, he enters a compartment and kisses the sole occupant, Pamela, in a desperate attempt to hide his face and escape detection. She frees herself from his unwanted embrace and alerts the policemen, who stop the train on the Forth Bridge. Hannay then escapes, hiding behind the bridge's truss. 
Question: What is the full name of the person that the police are searching the train for?
Example Output: Richard Hannay.

Example Input: Passage: Gilmour recorded his second solo album, About Face, in 1984, and used it to express his feelings about a variety of topics, from the murder of John Lennon to his relationship with Waters. He later stated that he used the album to distance himself from Pink Floyd. Soon afterwards, Waters began touring his first solo album, The Pros and Cons of Hitch Hiking. Wright formed Zee with Dave Harris and recorded Identity, which went almost unnoticed upon its release. Mason released his second solo album, Profiles, in August 1985.Following the release of The Pros and Cons of Hitch Hiking, Waters publicly insisted that Pink Floyd would not reunite. He contacted O'Rourke to discuss settling future royalty payments. O'Rourke felt obliged to inform Mason and Gilmour, which angered Waters, who wanted to dismiss him as the band's manager. He terminated his management contract with O'Rourke and employed Peter Rudge to manage his affairs. Waters wrote to EMI and Columbia announcing he had left the band, and asked them to release him from his contractual obligations. Gilmour believed that Waters left to hasten the demise of Pink Floyd. Waters later stated that, by not making new albums, Pink Floyd would be in breach of contract—which would suggest that royalty payments would be suspended—and that the other band members had forced him from the group by threatening to sue him. He then went to the High Court in an effort to dissolve the band and prevent the use of the Pink Floyd name, declaring Pink Floyd "a spent force creatively." When his lawyers discovered that the partnership had never been formally confirmed, Waters returned to the High Court in an attempt to obtain a veto over further use of the band's name. Gilmour responded by issuing a carefully worded press release affirming that Pink Floyd would continue to exist. He later told The Sunday Times: "Roger is a dog in the manger and I'm going to fight him." In 2013, Waters said he had failed to appreciate that the Pink Floyd name had commercial value independent of the band members, and was wrong to have attempted to stop the others using it. 
Question: What is the last name of the person whose affairs were managed by Peter Rudge?
Example Output:
Waters.
