input question: A friend asked me to answer this question: What is the last name of the person who was was physically restrained by Nilsson?, using the article: ABKCO Industries was formed in 1968 by Allen Klein as an umbrella company to ABKCO Records. Klein hired May Pang as a receptionist in 1969. Through involvement in a project with ABKCO, Lennon and Ono met her the following year. She became their personal assistant. In 1973, after she had been working with the couple for three years, Ono confided that she and Lennon were becoming estranged. She went on to suggest that Pang should begin a physical relationship with Lennon, telling her, "He likes you a lot." Astounded by Ono's proposition, Pang nevertheless agreed to become Lennon's companion. The pair soon left for Los Angeles, beginning an 18-month period he later called his "lost weekend". In Los Angeles, Pang encouraged Lennon to develop regular contact with Julian, whom he had not seen for two years. He also rekindled friendships with Starr, McCartney, Beatles roadie Mal Evans, and Harry Nilsson. While Lennon was drinking with Nilsson, he misunderstood something that Pang had said and attempted to strangle her. Lennon relented only after he was physically restrained by Nilsson.In June, Lennon and Pang returned to Manhattan in their newly rented penthouse apartment where they prepared a spare room for Julian when he visited them.  Lennon, who had been inhibited by Ono in this regard, began to reestablish contact with other relatives and friends.  By December, he and Pang were considering a house purchase, and he refused to accept Ono's telephone calls. In January 1975, he agreed to meet Ono, who claimed to have found a cure for smoking. After the meeting, he failed to return home or call Pang. When Pang telephoned the next day, Ono told her that Lennon was unavailable because he was exhausted after a hypnotherapy session. Two days later, Lennon reappeared at a joint dental appointment; he was stupefied and confused to such an extent that Pang believed he had been brainwashed. Lennon told Pang that his separation from Ono was now over, although Ono would allow him to continue seeing her as his mistress., what would be the answer ????
output answer: Lennon

A friend asked me to answer this question: What territories were not conquered by the Spanish?, using the article: Christopher Columbus discovered the Americas for the Kingdom of Castile and León in 1492. By 1580 this had unified with neighbouring kingdoms to form one Spanish kingdom. Private adventurers thereafter entered into contracts with the Spanish Crown to conquer the newly discovered lands in return for tax revenues and the power to rule. In the first decades after the discovery, the Spanish colonised the Caribbean and established a centre of operations on the island of Cuba. They heard rumours of the rich empire of the Aztecs on the mainland to the west and, in 1519, Hernán Cortés set sail with eleven ships to explore the Mexican coast. By August 1521 the Aztec capital of Tenochtitlan had fallen to the Spanish. Within three years of the fall of Tenochtitlan the Spanish had conquered a large part of Mexico, extending as far south as the Isthmus of Tehuantepec. The newly conquered territory became New Spain, headed by a viceroy who answered to the Spanish Crown via the Council of the Indies. Cortés despatched Pedro de Alvarado with an army to conquer the Mesoamerican kingdoms of the Guatemalan Sierra Madre and neighbouring Pacific plain; the military phase of the establishment of the Spanish colony of Guatemala lasted from 1524 to 1541. The Captaincy General of Guatemala had its capital at Santiago de los Caballeros de Guatemala and covered a wide territory that also included the Mexican state of Chiapas as well as El Salvador, Honduras and Costa Rica. The Spanish imposed colonial rule over Yucatán between 1527 and 1546, and over Verapaz from the 16th to the 17th centuries, leaving the area between – essentially Petén and much of Belize – independent long after surrounding peoples had been subjugated., what would be the answer ?
----
Answer: Petén

Problem: Given the question: A friend asked me to answer this question: What was the full name of the person that had a branch of their expedition explore the Teton region?, using the article: The first U.S. Government sponsored expedition to enter Jackson Hole was the 1859–60 Raynolds Expedition. Led by U.S. Army Captain William F. Raynolds and guided by mountain man Jim Bridger, it included naturalist F. V. Hayden, who later led other expeditions to the region. The expedition had been charged with exploring the Yellowstone region, but encountered difficulties crossing mountain passes due to snow. Bridger ended up guiding the expedition south over Union Pass then following the Gros Ventre River drainage to the Snake River and leaving the region over Teton Pass. Organized exploration of the region was halted during the American Civil War but resumed when F. V. Hayden led the well-funded Hayden Geological Survey of 1871. In 1872, Hayden oversaw explorations in Yellowstone, while a branch of his expedition known as the Snake River Division was led by James Stevenson and explored the Teton region. Along with Stevenson was photographer William Henry Jackson who took the first photographs of the Teton Range. The Hayden Geological Survey named many of the mountains and lakes in the region. The explorations by early mountain men and subsequent expeditions failed to identify any sources of economically viable mineral wealth. Nevertheless, small groups of prospectors set up claims and mining operations on several of the creeks and rivers. By 1900 all organized efforts to retrieve minerals had been abandoned. Though the Teton Range was never permanently inhabited, pioneers began settling the Jackson Hole valley to the east of the range in 1884. These earliest homesteaders were mostly single men who endured long winters, short growing seasons and rocky soils that were hard to cultivate. The region was mostly suited for the cultivation of hay and cattle ranching. By 1890, Jackson Hole had an estimated permanent population of 60. Menor's Ferry was built in 1892 near present-day Moose, Wyoming to provide access for wagons to the west side of the Snake River. Ranching increased significantly from 1900 to 1920,..., what would be the answer ?

The answer is:
F. V. Hayden
