Q: Passage: Soon after the end of World War II a young English woman, Amy Atkins, goes back to the London flat where she and her best friend, Tillie Grey, once used to live. The housekeeper Mrs. Tubbs meets Amy and reveals to her that Tillie went ill right before she was off to America to look for the man she married during the war. Tillie died from her illness before she could make her journey, and left two orphaned twin children, Joyce and Johnny Jr. To honor her old friend and make her husband honour his obligations Amy decides to make the journey that Tillie had planned and complete task of finding her husband, Johnny. Amy modifies Tillie's new passport and travels to America by boat on the ticket Tillie had bought, posing as her best friend.
The only information Amy has about her best friend's husband is that his name is John "Johnny" Grey, and that he is supposed to reside in Rochester, NY. To get more information of the whereabouts of Johnny, she asks aid from the American Red Cross. Just when Amy is about to land at the docks in New York City, a man named John Grey - a New York architect living in Rochester - gets a telegram informing him of the arrival of his wife and children by boat. This John Grey (Franchot Tone is shocked, since he is about to marry the socialité daughter, Lois (Frances Rafferty, of his boss Mr. Evans of his architectural firm that same weekend. Thinking it may by chance be a man with the same name Johnny contacts all the "John Grey"s of Rochester to find out that none were married in England. 
Question: What is the last name of the socialite Louis' father?

Q: Passage: After the Southwest became part of the U.S., explorers continued to look for good east–west routes along the 35th parallel. In 1853, a crew led by U.S. Army Lieutenant Amiel Whipple surveyed along a sandy wash in the northern part of the Petrified Forest. So impressed was Whipple by the petrified wood along the banks of the arroyo that he named it Lithodendron Creek (Stone Tree Creek). Geologist Jules Marcou, a member of the Whipple expedition, observed that the petrified trees were from the Triassic.A slightly later route along the parallel was a wagon road, built between 1857 and 1860, that involved experimental use of camels as transport. In the late 19th century, settlers and private stagecoach companies followed similar east–west routes. Homesteaders who stayed in the area developed cattle ranches on the grasslands, and cattle grazed in the Petrified Forest until the mid-20th century.Also close to the 35th parallel was the Atlantic and Pacific Railroad. Its opening in the early 1880s led to the founding of towns like Holbrook and Adamana. Visitors could stop at the Adamana train station, book a hotel room, and take a tour of what was then called the Chalcedony Forest. Over the years, the line changed hands, becoming the Atchison, Topeka and Santa Fe Railway, and then the BNSF. More than 60 BNSF trains, mostly carrying freight, pass through the park every day. U.S. Route 66, a former transcontinental auto highway developed in 1926 from part of the National Old Trails Road, ran parallel to the railroad tracks until it was decommissioned in 1985. The park has preserved within its boundaries a small grassy section of the road. Interstate 40, which crosses the park, replaced the older highway. 
Question: What town could you take a tour of the Chalcedony Forest from?

A: Adamana.

Q: Passage: The American Chemical Society (ACS) has used the Joseph Priestley House as a place to mark special celebrations. On July 31 and August 1, 1874, "seventy-seven chemists made a pilgrimage to the site to celebrate the centennial of chemistry". The date was chosen to mark the hundredth anniversary of Priestley's experiment producing oxygen by heating mercuric oxide with a magnifying lens and sunlight. These chemists came from 15 US states and the District of Columbia, Canada, and England, and their meeting at the house and a local school "is now recognized as the first National Chemistry Congress, and many ACS historians believe it led to ACS's formation two years later on April 6, 1876". On September 5, 1926, about 500 ACS members met again at the home to dedicate the small brick museum and to celebrate the meeting 50 years earlier (two survivors of that first meeting were present).Representatives of the ACS were present at the October 1970 dedication of the house as a museum. On April 25, 1974 around 400 chemists from the ACS Middle Atlantic Regional Meeting in Scranton came to visit the home. The Priestley Medal, the highest and oldest honor awarded by the ACS, was awarded to Paul Flory at the house that day. (A replica of the Priestley Medal is on display at the house.) On August 1, 1974—what has been labeled the bicentennial of the discovery of oxygen—over 500 chemists attending the third Biennial Conference on Chemical Education at State College traveled to the house to celebrate "Oxygen Day". In October 1976, the ACS celebrated its own centennial with a celebration in Northumberland. A 100-plus piece replica of Priestley's laboratory equipment, made by universities, corporations, and the Smithsonian Institution, was presented to the house for display. On April 13, 1983, ACS President Fred Basolo spoke at the house to celebrate Priestley's 250th birthday and as part of a first day of issue ceremony for the United States Postal Service's Joseph Priestley commemorative stamp. In 2001 the ACS again met at the house to celebrate the 125th anniversary of the society, and reenacted parts of the 1874 and 1926 celebrations, including a march to Priestley's grave, at which each participant left a red rose. 
Question: Where did 500 ACS members met again on September 5 1926?

A:
the Joseph Priestley House.
