Passage: Increasing tourist and commercial interest in petrified wood during the late 19th century began to alarm residents of the region. In 1895, the Arizona Territorial Legislature asked the U.S. Congress to create a petrified forest national park. Although this first attempt failed, in 1906 the Antiquities Act signed by President Theodore Roosevelt was used to create the Petrified Forest National Monument. Between 1934 and 1942, the federal Civilian Conservation Corps built road, trails, and structures in the monument, and the government acquired additional land in the Painted Desert section. The monument became a national park in 1962. Six years after the signing of the Wilderness Act in 1964 by President Lyndon B. Johnson, wilderness areas (where human activity is limited), were designated in the park. In 2004, President George W. Bush signed a bill authorizing the eventual expansion of the park from 93,353 acres (about 146 mi2 or 378 km2) to 218,533 acres (about 341 mi2 or 884 km2). Theft of petrified wood is still a problem. Despite a guard force of seven National Park Service rangers, fences, warning signs, and the threat of a $325 fine, an estimated 12 short tons (11,000 kg) of the fossil wood is stolen from the Petrified Forest every year.Jessee Walter Fewkes, the first archeologist to visit Puerco Ruin, predicted in the late 19th century that it would yield many artifacts. Conservationist John Muir conducted the first excavations of the ruin in 190506. Although he did not publish his findings, he urged the federal government to preserve Petrified Forest. Professional archeological work in the park began in the early 20th century when Walter Hough conducted excavations at Puerco Ruin and other sites. In 1919, a phytosaur skull was discovered near Blue Mesa in the Petrified Forest and sent to the Museum of Paleontology in Berkeley, California. In 1921, Annie Alexander, founder of the museum, visited Blue Mesa to collect more of the phytosaur and other specimens; this led to further excavations by paleontologist Charles Camp. Since then, more than 250 fossil sites have been documented in the park. In the 1930s, the Civil Works Administration funded research in the park by archeologists H.P. Mera and C.B. Cosgrove. A National Park Service resurvey of the Petrified Forest in the early 1940s identified most of the large sites with stone ruins, and subsequent surveys since 1978 have identified a total of more than 600 artifact sites, many of them small. Research in paleontology and archeology continues at the park in the 21st century.
Question: Who urged the federal government to preserve Petrified Forest?

Passage: Set in 2003, Huck Cheever is a young and talented poker player in Las Vegas haunted by his relationship with his estranged father, L.C. Cheever, a two-time World Series of Poker Champion. Huck is a regular in Vegas poker rooms but needs $10,000 to get a seat in the World Series of Poker Main Event.
After a good night at the Bellagio hotel's poker room, Huck goes to a party and meets aspiring singer Billie Offer, who has just arrived in town. Billie's older sister Suzanne warns her that Huck is "hustle 10, commitment zero." Back at the Bellagio, Huck is doing well at the tables before L.C. returns to town from the South of France. Huck greets his father coldly. The two play heads-up.
Loan shark Roy Durucher tells Huck that he plays poker as well as anybody, except for his reputation as a "blaster" (not patient enough) who always goes for broke. Roy proposes to stake Huck in the $10,000 main-event with a 60% 40% split of any winnings, but Huck refuses. After failing to borrow money from his friend Jack, Huck goes to Suzanne's place hoping for a loan. Instead he runs into Billie, who gets a call confirming that she has landed a job singing at a club.
Huck proposes a celebration and at Binion's Horseshoe he shows her how to play poker. L.C. arrives and shows Huck a wedding ring of Huck's late mother's that Huck had pawned and that L.C. has redeemed. Huck loses his winnings. Over dinner, he explains to Billie that his father stole from his mother before leaving her. Huck says his father taught him how to play on the kitchen table with "pennies, nickels, and dimes." They make love after dinner. As Billie sleeps, Huck steals money from Billie's purse.
Question: What are the full names of the two people who play heads-up?
