Passage: Bob Weston works for STOP, a scandal magazine whose owner and staff are proud of being regarded as the filthiest rag in America. One of Bob's colleagues has just written an article about Dr. Helen Gurley Brown, a young psychologist and author of the best-selling book Sex and the Single Girl, a self-help guide with advice to single women on how to deal with men. The article raises doubts on her experience with sex and relationships. Helen is very offended, having lost six appointments with patients due to the article discrediting her as a "23 year-old virgin.". Bob wants to follow up by interviewing her, but she refuses.
Bob's friend and neighbor, stocking manufacturer Frank Broderick, is having marriage issues with his strong-willed wife Sylvia, but can't find the time to go to a counselor. Therefore, Bob decides to impersonate Frank and go to Helen as a patient, with the goal of getting close to her in order to gather more information. In exchange, he'll report back to Frank her advice. During their first couple of sessions, Bob acts shy and smitten, and tries to gently seduce Helen. She seems to respond to Bob's courteous advances, all while insisting it's a transfer and that she'll play the role of Sylvia to the benefit of his therapy. After he fakes a suicide attempt, the two of them end up making out in her apartment, with Bob realizing he's actually falling for Helen, which is the reason he still has not written anything about her, prompting an ultimatum from his boss. 
Question: What is the last name of the person Helen pretends to be in therapy sessions?
Broderick.

Passage: Forty-eight Non-Indian people visited Yosemite Valley in 1855, including San Francisco writer James Mason Hutchings and artist Thomas Ayres. Hutchings wrote an article about his experience that was published in the July 12, 1855, issue of the Mariposa Gazette and Ayres' sketch of Yosemite Falls was published in late 1855; four of his drawings were presented in the lead article of the July 1856 and initial issue of Hutchings' Illustrated California Magazine. The article and illustrations created tourist interest in Yosemite and eventually led to its protection.Ayres returned in 1856 and visited Tuolumne Meadows in the area's high country. His highly detailed angularly exaggerated artwork and his written accounts were distributed nationally and an art exhibition of his drawings was held in New York City.
Hutchings took photographer Charles Leander Weed to Yosemite Valley in 1859; Weed took the first photographs of the valley's features, which were presented to the public in a September exhibition held in San Francisco. Hutchings published four installments of "The Great Yo-semite Valley" from October 1859 to March 1860 in his magazine and re-published a collection of these articles in his Scenes of Wonder and Curiosity in California, which remained in print into the 1870s.
Carleton Watkins exhibited his 17 by 22 in (43 by 56 cm) Yosemite views at the 1867 Paris International Exposition.Photographer Ansel Adams made his first trip to Yosemite in 1916; his photographs of the valley made him famous in the 1920s and 1930s. Adams willed the originals of his Yosemite photos to the Yosemite Park Association, and visitors can still buy direct prints from his original negatives. The studio in which the prints are sold was established in 1902 by artist Harry Cassie Best.Milton and Houston Mann opened a toll road to Yosemite Valley in 1856, up the South Fork of the Merced River. They charged the then considerable sum of two dollars per person until the road was bought by Mariposa County, after which it became free.
In 1856, settler Galen Clark discovered the Mariposa Grove of giant sequoia at Wawona, an indigenous encampment in what is now the southwestern part of the park. Clark completed a bridge over the South Fork of the Merced River in 1857 at Wawona for traffic headed toward Yosemite Valley and provided a way station for travelers on the road the Mann brothers built to the valley.Simple lodgings, later called the Lower Hotel, were completed soon afterward; the Upper Hotel, later renamed Hutchings House and eventually known as Cedar Cottage, was opened in 1859. In 1876, the more substantial Wawona Hotel was built to serve tourists visiting the nearby grove of big trees and those on their way to Yosemite Valley. Aaron Harris opened the first campground business in Yosemite in 1876. 
Question: What is the last name of the person in whose magazine four installments of "The Great Yo-semite Valley" were published?
Hutchings.

Passage: Pontius Pilate offers to release either Jesus of Nazareth or Barabbas, in keeping with the Passover custom. The crowd gathered for the pardoning chooses Barabbas, and Jesus is condemned to crucifixion. Returning to his friends, Barabbas asks for his lover, Rachel. His friends inform him that Rachel has become a follower of Christ. Rachel soon returns, but she is not happy to see Barabbas.
Barabbas witnesses the crucifixion of Jesus. As Jesus dies, the sky turns black, and Barabbas is shaken. He watches Christ's body sealed in the tomb. On the third morning, Barabbas finds the tomb open. Rachel tells him that Christ has risen, but Barabbas says it is an illusion, or that His followers have stolen the body. He visits the apostles; they do not know where He is, but also believe He is risen.
Rachel preaches in Jerusalem about the Christ. She is stoned to death at the insistence of the priests. Barabbas returns to his criminal ways and robs a caravan transporting several of the priests. He throws stones at one of them rather than fleeing, and is captured by Roman soldiers. The law forbids Pilate from executing someone who has been pardoned, so he sentences Barabbas to lifelong slavery in the sulfur mines of Sicily.
Barabbas survives this hellish existence for the next twenty years.  He is chained to Sahak, a sailor who was sent to the mines for allowing slaves to escape. Sahak is a Christian. Sahak at first hates Barabbas for being pardoned instead of "the Master", but the two men eventually become friends. Over time, Sahak becomes too weak to work. As the guards are about to kill him the mine is destroyed in an earthquake. Sahak and Barabbas are the only survivors. Julia, the superstitious wife of the local prefect, considers them blessed. The prefect is due to leave for Rome to be appointed to the Senate. Julia insists that Barabbas and Sahak accompany him for good luck. 
Question: Who is saved from execution by an earthquake?

Sahak.
