Question: 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?

Answer: Heartland Flyer.


Question: Passage: Donald's Dilemma starts with Daisy narrating her problem to an unseen psychologist through flashback scenes. Her problem started on a spring day when she was out on a date with Donald and a flower pot fell on his head. He regained consciousness soon enough but with some marked differences. His singing voice was improved to the degree in which it sounds identical to Frank Sinatra. However, Donald had no memory of who Daisy was. He became a well-known crooner and his rendition of "When You Wish Upon a Star" from Pinocchio (which had been released seven years earlier) became a hit, which gave him a large number of fans. Daisy's loss resulted in a number of psychological symptoms - she suffered from anorexia, insomnia and self-described insanity. An often censored scene features her losing her will to live and pointing a gun at her head, while in front of a table of other different suicidal methods, including a noose, a grenade, a bomb, a knife, and poison. She decided that she would see Donald once again, at any cost, but failed to do so. That's when she decided to go to the psychologist - and the flashback meets the actual time of the cartoon.
At the end of the cartoon, the psychologist determines that Donald would regain his memory of Daisy if another flower pot (with the same flower from the first pot, which Daisy kept as the only thing she had to remember Donald) would fall on his head. But he warns that his improved voice may be lost along with his singing career. He offers Daisy a dilemma. Either the world has its singer but Daisy loses him or Daisy regains Donald but the world loses him. Posed with the question "her or the world", Daisy answers with a resounding and possessive scream - "Me! Me! Me! MEEE!!". Soon, Donald returns to his old self and forgets about his singing career and Daisy regains her lover. 
Question: Whose singing voice improved after being hit on the head with a flower pot?

Answer: Donald.


Question: Passage: Terri Griffith is an aspiring teenage journalist in Phoenix who feels that her teachers don't take her articles seriously because of her good looks. After failing to get her dream job as a newspaper intern, she comes to the conclusion that it is because she is a girl.
With her parents out of town on a two-week Caribbean vacation, Terri decides to remedy the situation. Enrolling at a rival high school, she enlists the help of her little brother, Buddy, and her best friend Denise to disguise herself as a boy. Along the way she meets Rick Morehouse, a nerd who becomes her pet project. After helping him through an image makeover and encouraging him to start talking to girls, Terri starts to fall for him.
After many episodes in and out of school, including fending off a group of bullies led by bodybuilder Greg Tolan, dealing with her real college boyfriend Kevin and being set up on a blind date with a potential new girlfriend named Sandy, Terri manages to be accepted as "one of the guys". However, she is stunned when she turns in an article and her teacher still criticizes her work, making Terri realize her gender and looks were never the issue.
At the senior prom, a jealous Greg picks a fight with Rick, who ultimately trounces the bully in front of the entire class. When Terri's boyfriend shows up unexpectedly and discovers the ruse, Rick assumes that Terri's big secret was that she was gay. To prove otherwise, Terri opens her shirt and reveals her breasts to Rick. Although she admits to loving him, Rick rejects her, prompting a desperate Terri to kiss him in front of everyone. To placate the awestruck students, Rick derisively announces that Terri "has tits" before leaving the prom and Terri behind.
Heartbroken and humiliated, Terri retreats to her room and writes a long article on what it is like to be a girl in boy's clothing, detailing all of her experiences, both good and bad. 
Question: What is the first name of the person that the nerd trounces in front of the entire class?

Answer:
Greg.
