Input: Consider Input: Passage: Transportation in Oklahoma is generated by an anchor system of Interstate Highways, inter-city rail lines, airports, inland ports, and mass transit networks. Situated along an integral point in the United States Interstate network, Oklahoma contains three primary Interstate highways and four auxiliary Interstate Highways. In Oklahoma City, Interstate 35 intersects with Interstate 44 and Interstate 40, forming one of the most important intersections along the United States highway system.More than 12,000 miles (19,000 km) of roads make up the state's major highway skeleton, including state-operated highways, ten turnpikes or major toll roads, and the longest drivable stretch of Route 66 in the nation. In 2008, Interstate 44 in Oklahoma City was Oklahoma's busiest highway, with a daily traffic volume of 123,300 cars. In 2010, the state had the nation's third-highest number of bridges classified as structurally deficient, with nearly 5,212 bridges in disrepair, including 235 National Highway System Bridges.Oklahoma's largest commercial airport is Will Rogers World Airport in Oklahoma City, averaging a yearly passenger count of more than 3.5 million (1.7 million boardings) in 2010. Tulsa International Airport, the state's second-largest commercial airport, served more than 1.3 million boardings in 2010. Between the two, six airlines operate in Oklahoma. In terms of traffic, R. L. Jones Jr. (Riverside) Airport in Tulsa is the state's busiest airport, with 335,826 takeoffs and landings in 2008. Oklahoma has over 150 public-use airports.Oklahoma is connected to the nation's rail network via Amtrak's Heartland Flyer, its only regional passenger rail line. It currently stretches from Oklahoma City to Fort Worth, Texas, though lawmakers began seeking funding in early 2007 to connect the Heartland Flyer to Tulsa.Two inland ports on rivers serve Oklahoma: the Port of Muskogee and the Tulsa Port of Catoosa. The state's only port handling international cargo, the Tulsa Port of Catoosa is the most inland ocean-going port in the nation and ships over two million tons of cargo each year. Both ports are on the McClellan–Kerr Arkansas River Navigation System, which connects barge traffic from Tulsa and Muskogee to the Mississippi River via the Verdigris and Arkansas rivers, contributing to one of the busiest waterways in the world. 
Question: What is the name of Amtrack's rail line that currently stretches from Oklahoma City to Fort Worth Texas?

Output: Heartland Flyer.


Input: Consider Input: Passage: Lennon met Cynthia Powell (1939–2015) in 1957, when they were fellow students at the Liverpool College of Art. Although Powell was intimidated by Lennon's attitude and appearance, she heard that he was obsessed with the French actress Brigitte Bardot, so she dyed her hair blonde. Lennon asked her out, but when she said that she was engaged, he screamed out, "I didn't ask you to fuckin' marry me, did I?" She often accompanied him to Quarrymen gigs and travelled to Hamburg with McCartney's girlfriend to visit him. Lennon was jealous by nature and eventually grew possessive, often terrifying Powell with his anger and physical violence. Lennon later said that until he met Ono, he had never questioned his chauvinistic attitude toward women. He said that the Beatles song "Getting Better" told his own story, "I used to be cruel to my woman, and physically – any woman. I was a hitter. I couldn't express myself and I hit. I fought men and I hit women. That is why I am always on about peace."Recalling his July 1962 reaction when he learned that Cynthia was pregnant, Lennon said, "There's only one thing for it Cyn. We'll have to get married." The couple wed on 23 August at the Mount Pleasant Register Office in Liverpool, with Brian Epstein serving as best man. His marriage began just as Beatlemania was taking off across the UK. He performed on the evening of his wedding day and would continue to do so almost daily from then on. Epstein feared that fans would be alienated by the idea of a married Beatle, and he asked the Lennons to keep their marriage secret. Julian was born on 8 April 1963; Lennon was on tour at the time and did not see his infant son until three days later.Cynthia attributed the start of the marriage breakdown to Lennon's use of LSD, and she felt that he slowly lost interest in her as a result of his use of the drug. When the group travelled by train to Bangor, Wales in 1967 for the Maharishi Yogi's Transcendental Meditation seminar, a policeman did not recognise her and stopped her from boarding. She later recalled how the incident seemed to symbolise the end of their marriage. After Cynthia arrived home at Kenwood, she found Lennon with Ono and left the house to stay with friends. Alexis Mardas later claimed to have slept with her that night, and a few weeks later he informed her that Lennon was seeking a divorce and custody of Julian on the grounds of her adultery with him. After negotiations, Lennon capitulated and agreed to let her divorce him on the same grounds. The case was settled out of court in November 1968, with Lennon giving her £100,000 ($240,000 in US dollars at the time), a small annual payment and custody of Julian. 
Question: What is the first name of the child of the person that began to use LSD and lose interest in his wife?

Output: Julian.


Input: Consider Input: Passage: Letty Strong was raised in a good family, but became pregnant and ran away from home. She was taken in by elderly Fuzzy, and gave birth to Mickey in the back room of Fuzzy's bookstore at the age of fifteen. Embittered, she taught Mickey to be street smart so he will never be taken advantage of like her. Fuzzy strongly disapproves of how she is raising her son. Now seven years old, Mickey skips school and does as he pleases. Meanwhile, Letty earns a living by entertaining buyers so they will give business to her friend Steve Karns.
A milk truck driven by Malcolm "Mal" Trevor hits Mickey as he is rollerskating in the street. When Letty's lawyer, Adolphe, learns that Mal is the wealthy president of Amalgamated Dairies (out checking every aspect of his large business), he talks Letty into seizing the opportunity to make some money. They get Mickey to lie about the extent of his injuries. However, during the trial, Mal's attorney produces films showing Mickey fully recovered. The irate judge has Mickey taken from Letty and put in an institution for boys.
Mal and his wife Alyce have no children. Mal offers to adopt Mickey, with Letty's approval, so she can see her son more frequently. Mickey thrives on Mal's country estate and the loving parenting he receives.
Letty is not satisfied with this arrangement; she wants her son back. Adolph suggests she seduce Mal and blackmail him into giving her Mickey (as well as money) with a recording of their conversation. The plan works; Mal admits he has fallen in love with her, and they spend the night together. The next morning, however, Mal informs a surprised Letty that he has told his wife. Alyce is willing to sacrifice herself for Mal's happiness. Letty comes to realize her genuine feelings for Mal, and breaks up with him, pretending to have only been toying with him. She then goes back to Fuzzy and asks for her old job back at the bookstore. 
Question: What is the last name of the person who owns a country estate?


Output: Trevor.
