Input: Consider Input: Passage: Three years after the destruction of the Death Star, the Rebel Alliance, led by Princess Leia, has set up a new base on the ice planet of Hoth. The Imperial fleet, led by Darth Vader, continues to hunt for the new Rebel base by dispatching probe droids across the galaxy. Luke Skywalker is captured by a wampa while investigating one such probe, but manages to escape from the wampa's lair with his lightsaber. Before Luke succumbs to hypothermic sleep, the Force ghost of his late mentor, Obi-Wan Kenobi, instructs him to go to Dagobah to train under Jedi Master Yoda. Han Solo locates Luke and cuts open the tauntaun he rode there on to keep his friend warm; they wait there until being rescued by a search party the next morning.
Meanwhile, the probe alerts the Imperial fleet to the Rebels' location. The Empire launches a large-scale attack using AT-AT walkers to capture the base, which forces the Rebels to retreat. Han and Leia escape with C-3PO and Chewbacca on the Millennium Falcon, but the ship's hyperdrive malfunctions. They hide in an asteroid field, where Han and Leia grow closer amidst tension and briefly kiss. Vader summons bounty hunters to assist in finding the Falcon. Luke, meanwhile, escapes with R2-D2 in his X-wing fighter and crash-lands on the swamp planet of Dagobah. He meets a diminutive creature who reveals himself to be Yoda; after conferring with Obi-Wan's spirit, Yoda reluctantly accepts Luke as his student. 
Question: Who is told to go train under Yoda?

Output: Luke.


Input: Consider Input: Passage: The Creed family—Louis, Rachel, and their children Ellie and Gage—move from Chicago to rural Ludlow, Maine, after Louis is offered a job as a doctor with the University of Maine. They befriend their elderly neighbor Jud Crandall, who takes them to an isolated pet cemetery (misspelled "sematary") in the forest behind the Creed's new home.
On his first day at work, Louis encounters Victor Pascow, a jogger who has been mortally injured after being hit by a truck. He warns Louis about the pet cemetery before he dies, calling Louis by name despite the fact they have not previously met. That night, Pascow comes to Louis as a ghost and leads him to the Pet Sematary, warning him not to cross the barrier because the ground beyond is "sour". Louis awakens, assuming it was a dream, but notices his feet are covered in dirt.
During Thanksgiving while the family is gone, Ellie's cat, Church, is run down on the highway. Realizing that Ellie will be devastated, Jud takes Louis beyond the cemetery and deep into the woods, where they reach an ancient Micmac burial ground. Jud instructs Louis to bury the cat and warns him not to tell anyone else about what they have done. The next day a reanimated Church returns to the house, a shell of what he was before; he stinks, moves sluggishly, and is vicious towards Louis. Jud explains that as a boy he himself revived his beloved pet dog in the Micmac ground, and that although the cat might be different, it will save Ellie the grief of losing her favorite pet.
Sometime later, the young Gage is killed by a truck along the same highway. The family is devastated, and Jud anticipates that Louis is considering burying his son in the Micmac ground, although Louis denies it. Jud believes that introducing Louis to the ritual ground aroused the malevolent forces present there, which caused Gage's death. 
Question: Who befriends an elderly neighbor?

Output: Louis.


Input: Consider Input: Passage: Steven Lee Lukather (born October 21, 1957) is an American guitarist, singer, songwriter, arranger and record producer, best known as a founding member of Toto. A prolific session musician, Lukather has recorded guitar tracks for more than 1,500 albums representing a broad array of artists and genres. He has also contributed to albums and hit singles as a songwriter, arranger and producer. Lukather was a prominent contributor to several studio albums by Michael Jackson, including Thriller, the best-selling album of all time. Lukather has released seven solo albums, the latest of which, Transition, was released in January 2013.
In 1976, when Lukather was nineteen years old, he was invited by his high school friends David Paich and the Porcaro brothers Steve and Jeff to join them in forming their band, Toto. He has been a member of the band ever since it began, and is still fully contributing to their album composition and touring. Lukather's reputation as a guitarist and his association with Paich and the Porcaro brothers, who also became established artists, allowed him to secure a steady flow of session work in the 1970s and 1980s. Lukather has been nominated for twelve Grammy Awards, and has won five. While his work with Toto was predominantly based on pop rock music and his solo work ventures into progressive rock and hard rock, many of Lukather's side-projects are focused on jazz fusion. He held a long-time collaboration with jazz guitarist Larry Carlton that produced a Grammy-winning live album, and he was a member of the jazz fusion band Los Lobotomys, a collaboration of notable session musicians. Since 2012, Lukather has toured with former Beatles drummer Ringo Starr's live supergroup, the All-Starr Band.
Influenced by such blues-rock guitarists as Jimi Hendrix and Jimmy Page, and such jazz fusion players as Al Di Meola and Frank Gambale, Lukather is known for a "melodic and intense" playing style. He is also recognized for his efficiency in the studio, often recording tracks in one take using minimal sound processing. While he once used many guitar effects in the studio and on stage, he now frequently disparages such practice, and instead advocates clean tones and minimal studio processing. Lukather plays primarily a signature electric guitar manufactured by Ernie Ball Music Man bearing his nickname, Luke. He also plays Yamaha and Ovation Adamas series acoustic–electric guitars. 
Question: What is the last name of the person who held a long-time collaboration with jazz guitarist Larry Carlton that produced a Grammy-winning live album?


Output: Lukather.
