In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

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?
Heartland Flyer.

Passage: Eakins referred to the painting as Swimming in 1885, and as The Swimmers in 1886. The title The Swimming Hole dates from 1917 (the year after Eakins died), when the work was so described by the artist's widow, Susan Macdowell Eakins. Four years later, she titled the work The Old Swimming Hole, in reference to the 1882 poem The Old Swimmin'-Hole; by James Whitcomb Riley. The Amon Carter Museum has since returned to Eakins' original title, Swimming.The painting shows Eakins and five friends or students bathing at Dove Lake, an artificial lake in Mill Creek outside Philadelphia. Each of the men is looking at the water, in the words of Martin A. Berger, "apparently lost in a contemplative moment". Eakins' precise rendering of the figures has enabled scholars to identify all those depicted in the work. They are (from left to right): Talcott Williams (1849–1928), Benjamin Fox (c. 1865 – c. 1900), J. Laurie Wallace (1864–1953), Jesse Godley (1862–1889), Harry the dog (Eakins' Irish Setter, c. 1880–90), George Reynolds (c. 1839–89), and Eakins himself. The rocky promontory on which several of the men rest is the foundation of the Mill Creek mill, which was razed in 1873. It is the only sign of civilization in the work—no shoes, clothes, or bath houses are visible. The foliage in the background provides a dark background against which the swimmers' skin tones contrast.
The positioning of the bodies and their musculature refers to classical ideals of physical beauty and masculine camaraderie evocative of Greek art. The reclining figure is a paraphrase of the Dying Gaul, and is juxtaposed with the far less formal self-depiction by the artist. It is possible that Eakins was seeking to reconcile an ancient theme with a modern interpretation; the subject was contemporary, but the poses of some of the figures recall those of classical sculpture. One possible influence by a contemporary source was Scène d'été, painted in 1869 by Frédéric Bazille (1841–70). It is not unlikely that Eakins saw the painting at the Salon while studying in Paris, and would have been sympathetic to its depiction of male bathers in a modern setting.In Eakins' oeuvre, The Swimming Hole was immediately preceded by a number of similar works on the Arcadian theme. These correspond to lectures he gave on Ancient Greek sculpture and were inspired by the Pennsylvania Academy's casts of Phidias' Pan-Athenaic procession from the Parthenon marbles. A series of photographs, relief sculptures, and oil sketches culminated in the 1883 Arcadia, a painting that also featured nude figures—posed for by a student, a nephew, and the artist's fiancée—in a pastoral landscape. 
Question: What painter possibly influenced Eakins in the painting of The Swimming Hole?
Frédéric Bazille.

Passage: After returning from the United States after the launch of her debut studio album The Family Jewels (2010), Diamandis considered creating a character which would become the centerpiece of her follow-up project. She commented that she was inspired by the "Tumblr generation" to photograph herself in several places across the United States, appearing as a different persona in each picture to mimick the anonymity of the "mini-stars of the internet". The final product became "a cold, ruthless character who wasn't vulnerable", which she later named "Electra Heart" and detailed as a tool to represent a combination of elements associated with the American Dream and Greek tragedy, and added that visuals would merge the differing concepts into a cohesive idea.Diamandis first announced Electra Heart in August 2011; it was initially planned to become a three-piece project inspired by American culture in the 1970s, although it eventually evolved into her second studio album. Diamandis originally planned to release the record as a "side project" under an entity separate from Marina and the Diamonds, although her management disapproved. The track "Living Dead" was the first recorded during its production, and approximately 22 songs were recorded for potential inclusion on the album. She later commented that the record was dedicated to "dysfunctional love", elaborating that "rejection is a universally embarrassing topic and Electra Heart is my response to that." Diamandis stated that Electra Heart was influenced by Madonna, Marilyn Monroe, and Queen of France Marie Antoinette; she described Madonna as being "fearless" and felt that she showcased a desire to be a successful artist beyond fame and wealth. Diamandis told Glamour that Britney Spears influenced a "double-sided" theme for the record of both "innocence" and "darkness". She described the final product as being "a bit cringe" and reflective of her personal experiences, although noted that its promotional campaign would be "pink and fluffy". 
Question: What is the name of the singer that said Madonna was fearless?

Marina and the Diamonds.
