Question: Passage: Presley's rise to national attention in 1956 transformed the field of popular music and had a huge effect on the broader scope of popular culture. As the catalyst for the cultural revolution that was rock and roll, he was central not only to defining it as a musical genre but in making it a touchstone of youth culture and rebellious attitude. With its racially mixed origins—repeatedly affirmed by Presley—rock and roll's occupation of a central position in mainstream American culture facilitated a new acceptance and appreciation of black culture. In this regard, Little Richard said of Presley, "He was an integrator. Elvis was a blessing. They wouldn't let black music through. He opened the door for black music." Al Green agreed: "He broke the ice for all of us." President Jimmy Carter remarked on his legacy in 1977: "His music and his personality, fusing the styles of white country and black rhythm and blues, permanently changed the face of American popular culture. His following was immense, and he was a symbol to people the world over of the vitality, rebelliousness, and good humor of his country." Presley also heralded the vastly expanded reach of celebrity in the era of mass communication: at the age of 21, within a year of his first appearance on American network television, he was one of the most famous people in the world.Presley's name, image, and voice are instantly recognizable around the globe. He has inspired a legion of impersonators. In polls and surveys, he is recognized as one of the most important popular music artists and influential Americans. "Elvis Presley is the greatest cultural force in the twentieth century", said composer and conductor Leonard Bernstein. "He introduced the beat to everything and he changed everything—music, language, clothes. It's a whole new social revolution—the sixties came from it." In the words of John Lennon, "Nothing really affected me until Elvis." Bob Dylan described the sensation of first hearing Presley as "like busting out of jail".
On the 25th anniversary of Presley's death, The New York Times asserted, "All the talentless impersonators and appalling black velvet paintings on display can make him seem little more than a perverse and distant memory. But before Elvis was camp, he was its opposite: a genuine cultural force. ... Elvis' breakthroughs are underappreciated because in this rock-and-roll age, his hard-rocking music and sultry style have triumphed so completely." Not only Presley's achievements, but his failings as well, are seen by some cultural observers as adding to the power of his legacy, as in this description by Greil Marcus:.

Answer: What is the last name of the person who said listening to music by the man who rose to national attention in 1956 was "like busting out of jail"?


Question: Passage: Musician, Charlie Rogers, is fired from a gig at a teahouse run by Lou, after brawling with several college students in the parking lot. After a night in jail, Charlie hits the road on his Honda 305 Superhawk motorcycle. He spots Cathy Lean driving with her father Joe, and their employer, Maggie Morgan. When Charlie tries to become friendly with Cathy, Joe forces him off the road and the bike is wrecked after crashing into a wooden fence.
Maggie offers him a place to stay and a job with her struggling traveling carnival while the bike is being repaired. Charlie becomes a "carnie", a roustabout. Maggie recognizes his musical talents and promotes him to feature attraction. His act soon draws large crowds. Off stage, Charlie romances Cathy, which creates animosity with Joe. After the two men repeatedly clash and Charlie is accused of holding back a customer's lost wallet that Joe was accused of stealing, Charlie leaves to star in the much better financed show of rival carnival producer Harry Carver.
Once again, he is a great success. However, when Charlie learns that Maggie is facing bankruptcy, he returns to her carnival. In the musical finale, he is happily reunited with Cathy.

Answer: What is the full name of the person that Maggie offers a place to stay?


Question: Passage: Although the Silk Road from China to Europe and the Western World was initially formulated during the reign of Emperor Wu (141–87 BC) during the Han, it was reopened by the Tang in 639 when Hou Junji (d. 643) conquered the West, and remained open for almost four decades. It was closed after the Tibetans captured it in 678, but in 699, during Empress Wu's period, the Silk Road reopened when the Tang reconquered the Four Garrisons of Anxi originally installed in 640, once again connecting China directly to the West for land-based trade. The Tang captured the vital route through the Gilgit Valley from Tibet in 722, lost it to the Tibetans in 737, and regained it under the command of the Goguryeo-Korean General Gao Xianzhi. When the An Lushan Rebellion ended in 763, the Tang Empire had once again lost control over its western lands, as the Tibetan Empire largely cut off China's direct access to the Silk Road. An internal rebellion in 848 ousted the Tibetan rulers, and Tang China regained its northwestern prefectures from Tibet in 851. These lands contained crucial grazing areas and pastures for raising horses that the Tang dynasty desperately needed.Despite the many expatriate European travelers coming into China to live and trade, many travelers, mainly religious monks and missionaries, recorded the strict border laws that the Chinese enforced. As the monk Xuanzang and many other monk travelers attested to, there were many Chinese government checkpoints along the Silk Road that examined travel permits into the Tang Empire. Furthermore, banditry was a problem along the checkpoints and oasis towns, as Xuanzang also recorded that his group of travelers were assaulted by bandits on multiple occasions.
The Silk Road also affected Tang dynasty art. Horses became a significant symbol of prosperity and power as well as an instrument of military and diplomatic policy. Horses were also revered as a relative of the dragon.

Answer:
What connected China to the West for land-based trade?
