Input: Consider Input: Passage: Steve Everett, an Oakland journalist recovering from alcoholism, is assigned to cover the execution of convicted murderer Frank Beechum following the death of Everett's colleague, Michelle Ziegler, who had originally been assigned to the story.
Everett investigates the background to the case and comes to suspect that Beechum has been wrongly convicted of murdering Amy Wilson. He gets permission from his editor's boss to investigate, and is told that the top editor would call the Governor, and that would do the job, if Everett gets hard proof. He thus has a little over 12 hours to confirm his hunch and save Beechum.
Everett interviews a prosecution witness, Dale Porterhouse, who saw Beechum at the store with a gun. Everett questions Porterhouse's account, saying that, because of the layout of the store, he could not have seen a gun in Beechum's hand.
Everett confronts D.A. Cecelia Nussbaum, who reveals that, a young man, Warren, was interviewed and claimed he had stopped at the store to buy a soda and saw nothing. Everett decides that Warren, never called as a witness, is probably the real killer. He breaks into the deceased reporter's house, suspecting that she had been onto something and finds her file on Warren. Meanwhile, Warden Luther Plunkett also starts to have doubts about Beechum's guilt.
Everett falls out with his bosses and is fired on the spot, but he points out that his contract entitles him to adequate notice. They ask him how much notice he requires, and, looking at his watch, he says 6 hours and 7 minutes. He tracks down Angela Russel, Warren's grandmother. She tells him that her grandson could not have been the murderer, and berates him for the lack of interest from the press when Warren himself was killed in a mugging two years after Amy's murder.
Question: What is the full name of the person that claims Dale Porthouse could not have see a gun in the store?

Output: Steve Everett.

Input: Consider Input: Passage: When Ella Finch and her sister Kate inherit $30,000 each just after the end of World War I, Ella becomes dissatisfied with her dull life in South Bend, Indiana, and with Kate's butcher boyfriend Willis. She is convinced she can rectify both problems by taking Kate to New York City. Her wisecracking cigar salesman husband Ernie is unable to change her mind, so he reluctantly goes along, postponing a promotion at work by claiming to his boss, A. J. Gluskoter, that his wife is sick and needs a stay at a sanitarium. On the train, they meet New Yorker Francis Griffin. Ernie is less impressed with him than his wife and sister-in-law.
In New York, Ella helps Katie try to win over Francis, but it turns out that he is actually infatuated with Ella. She has to punch him to fend off his unexpected advances. Ernie shows up later and knocks him down too.
Ella then rents an apartment. Ella meets their wealthy neighbor, Lucius Trumball, who invites them all over for drinks. Ella is delighted, but Kate is not pleased when she discovers that Trumball is much older than her. Later she finds out he is also married when his wife returns unexpectedly from Timbuktu.
They return to the hotel they stayed at before, where they meet Herbert Daley, who owns race horses. At the track, Daley persuades them to bet on his horse. It wins, but then Daley's jockey, Sid Mercer, shows interest in Kate, much to Daley's annoyance. Kate secretly sees Sid while also going to the track with Daley with Ella and Ernie. Daley returns early from a trip and catches Sid kissing Kate, but Kate assures him there is nothing serious going on, and they become engaged.
Question: What is the last name of the person that Ella tries to help Katie win over?

Input: Consider 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 contractwhich would suggest that royalty payments would be suspendedand 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 first name of the person who said he had failed to appreciate that the Pink Floyd name had commercial value independent of the band members?
Output: Roger.
