Example Input: Passage: Shackleton's first task, on arriving at the Stromness station, was to arrange for his three companions at Peggoty Camp to be picked up. A whaler was sent round the coast, with Worsley aboard to show the way, and by the evening of 21 May all six of the James Caird party were safe.It took four attempts before Shackleton was able to return to Elephant Island to rescue the party stranded there. He first left South Georgia a mere three days after he had arrived in Stromness, after securing the use of a large whaler, The Southern Sky, which was laid up in Husvik Harbour. Shackleton assembled a volunteer crew, which had it ready to sail by the morning of 22 May. As the vessel approached Elephant Island they saw that an impenetrable barrier of pack ice had formed, some 70 miles (110 km) from their destination. The Southern Sky was not built for ice breaking, and retreated to Port Stanley in the Falkland Islands.On reaching Port Stanley, Shackleton informed London by cable of his whereabouts, and requested that a suitable vessel be sent south for the rescue operation. He was informed by the Admiralty that nothing was available before October, which in his view was too late. Then, with the help of the British Minister in Montevideo, Shackleton obtained from the Uruguayan government the loan of a tough trawler, Instituto de Pesca No. 1, which started south on 10 June. Again the pack thwarted them. In search of another ship, Shackleton, Worsley and Crean travelled to Punta Arenas, where they met Allan MacDonald, the British owner of the schooner Emma. McDonald equipped this vessel for a further rescue attempt, which left on 12 July, but with the same negative result—the pack defeated them yet again. Shackleton later named a glacier after McDonald on the Brunt Ice Shelf in the Weddell Sea. After problems arose in identifying this glacier, a nearby ice rise was renamed the McDonald Ice Rumples.By now it was mid-August, more than three months since Shackleton had left Elephant Island. Shackleton begged the Chilean Government to lend him Yelcho, a small steam tug that had assisted Emma during the previous attempt. They agreed; on 25 August, Yelcho—captained by Luis Pardo–set out for Elephant Island. This time, as Shackleton records, providence favoured them. The seas were open, and the ship was able to approach close to the island, in thick fog. At 11:40 a.m. on 30 August, the fog lifted, the camp was spotted and, within an hour, all the Elephant Island party were safely aboard, bound for Punta Arenas. 
Question: What vessel did MacDonald equip for a further rescue attempt?
Example Output: Emma.

Example Input: Passage: Audioslave's history dates back to October 18, 2000, when Rage Against the Machine's lead vocalist Zack de la Rocha announced he was leaving the band, citing a breakdown in its "decision-making process". Rage Against the Machine broke up as a result of de la Rocha's departure, but the remaining three members of the band—Tim Commerford, Tom Morello, and Brad Wilk—decided to stay together and announced plans to continue with a new vocalist. Several vocalists jammed with the three, including B-Real of Cypress Hill, but they did not want another rapper or anybody who sounded like de la Rocha. Contrary to popular belief, Layne Staley of Alice in Chains neither auditioned nor was asked to join the new project. Tom Morello denied this claim on his Twitter account in 2015. Music producer and friend Rick Rubin suggested that they play with Chris Cornell, the ex-frontman of Soundgarden. Rubin also persuaded the three of them to go into group therapy with performance coach Phil Towle after the breakup. Rubin was confident that with the right new voice, Rage Against the Machine had the potential to become a better band; he believed "it could turn into a Yardbirds-into-Led Zeppelin scenario." Commerford later credited Rubin for being the catalyst that brought Audioslave together. He called him "the angel at the crossroads" because "if it wasn't for him, I wouldn't be here today."The chemistry between Cornell and the other three was immediately apparent; as Morello described: "He stepped to the microphone and sang the song and I couldn't believe it. It didn't just sound good. It didn't sound great. It sounded transcendent. And...when there is an irreplaceable chemistry from the first moment, you can't deny it." The quartet wrote 21 songs during 19 days of rehearsal, and began working in the studio in late May 2001 with Rubin as producer, while sorting out the label and management issues. 
Question: What is the first name of the person Commerford credited with being the catalyst that brought Audioslave together?
Example Output: Rick.

Example Input: Passage: Lois Conway works as a music teacher at a local high school in a small town, where recently a woman was found murdered. When she starts receiving notes from an anonymous admirer, she suspects her favorite student Sandy is responsible, and tells him they could never be lovers. The notes grow more violent and when, in her latest letter, she is invited to meet at the school's lockers at night, Lois decides to visit, hoping to stop the young man. There, she is attacked by an initial shadowy figure, whom she later identifies as Leonard Bennett, the high school's star football player.
She successfully gets away, though drops her purse, and is aided by Lieutenant Harry Graham. Graham advises her to press charges, but Lois wants to drop the matter in hopes of it blowing over.
Back at home, she notices her purse on her table, and aware that the thief is in her home, orders him to leave. As he bashes through the door to get away, Lois is now certain that Leonard is her attacker.
Leonard is able to get home without his dominant and overbearing father noticing he is gone. Mr. Bennett lectures his son on the dangers of women, stimulated by the occurrence of him being left by his wife and Leonard's mother when he was very ill.
The following day, Lois reports the incident to the principal Pendleton, but when Leonard denies the whole matter, Pendleton protects the school's most valuable athletic asset by suggesting to Lois that she should provide evidence.
Soon the story spreads around school, and with gossip surrounding Lois allegedly pursuing Leonard, both her personal and professional life becomes a mess. One day, she pulls him out of class and tries to reason with him, but he refuses to listen to her. Meanwhile, she grows closer to Graham, who does not understand why she is sympathetic to Leonard. 
Question: What is the full name of the person who protects the football player after the incident is reported?
Example Output:
principal Pendleton.
