question:
Passage: Briarcliff Manor's original settlement was known as Whitson's Corners for brothers John H., Richard, and Reuben Whitson, who owned adjoining farms in the area totaling 400 acres (160 ha). Whitson's Corners was named after the corner of Pleasantville and South State Roads, where John H. Whitson's house, the Crossways, stood from 1820 until the 1940s. The Briarcliff Congregational Church's parish house currently stands at its former location. The neighboring community of Scarborough was known as Weskora until it was renamed in 1864, after resident William Kemey's ancestral hometown in Yorkshire. After the community was incorporated into Briarcliff Manor in 1906, the New York Central and Hudson River Railroad put up a sign reading "Briarcliff West" at the village's Scarborough station. Soon afterward, attributed to the neighborhood's pride over their name, that sign was thrown into the Hudson River and replaced with the original Scarborough sign.Briarcliff Manor derives from "Brier Cliff", a compound of the English words "brier" and "cliff". The name originated in Ireland as that of the family home of John David Ogilby, a professor of ecclesiastical history at the General Theological Seminary. Ogilby had named his New York summer home Brier Cliff after his family home in Ireland. In 1890, Walter Law bought James Stillman's 236-acre (96 ha) Briarcliff Farm and further developed it, later using the name Briarcliff for all his property. Law's friend, Andrew Carnegie, called him "The Laird of Briarcliff Manor"; since the title appealed to all concerned, the village was named "Briarcliff Manor". By 1897, the village post office and railroad station bore the name Briarcliff Manor. The village (and its name) were approved by its residents in a September 12, 1902 referendum; the name prevailed over other suggestions, including "Sing Sing East". On November 21, 1902, the village of Briarcliff Manor was established.The village is also known by several other names. It is conversationally called "Briarcliff", and often erroneously written as "Briar Cliff Manor" (although historically there has been little distinction). The village has been called "Briarcliff on the Hudson" by Mark Twain and Aileen Riggin; it is also known as "the Village of Briarcliff Manor". The name Briarcliff has also been applied to other municipalities, including the 470-person town of Briarcliffe Acres in South Carolina; in naming it, the town's founder had drawn inspiration from Briarcliff Manor's name. 
Question: What is the full name of the person that Andrew Carnegie, called him "The Laird of Briarcliff Manor"?
answer:
Walter Law.

Passage: Richie Donovan works as a professional thief for Groznyi, a wealthy businessman, to pay off his debt for being smuggled into the U.S. as a child. He pulls off an initially successful diamond heist, but it is botched when he is involved in two separate car accidents. He is given one last chance to pay off his debt by going to Russia to steal a priceless antique cross, locked in a safe in a Moscow penthouse apartment. Richie and his Russian accomplices, brothers Peter and Yuri, recover the cross; but their elevator becomes stuck on the uncompleted 13th floor. Believing the police have stopped the elevator, the thieves take their fellow passengers hostage to negotiate an escape. They agree to send one hostage down; but, when the elevator doors open on the ground floor, the hostage has mysteriously been beheaded. 
The remaining hostages quickly divide into two groups: a Christian group consisting of Sonya, Helena and Katerina, who are later joined by Yuri, and another group consisting of nerdy Dmitry, beautiful Anna, and incompetent security guard Boris.
In the confusion, the Christian group seizes firearms and takes control, shooting Peter. Katerina is sent to stand guard over Richie and the remainder of the hostages, while Sonya takes Yuri to a chamber where he is to sacrificed by a wild man in armor named Alex. Yuri escapes, but he is impaled by one of Alex's traps, complete with disco music and lighting. In his rage, Alex kills Katerina, allowing Richie and the hostages to escape. They discover Alex's lair, where he has been watching everyone using security cameras. A photo reveals that Alex is the twin brother of Sonya, and they both believe themselves to be descendants of Ivan the Terrible. The group splits when Richie and Anna decide to chase after Alex, while Boris and Dmitry prefer to rig the room with various traps they have constructed and wait for Alex to come to them. 
Question: Who are the people who think the authorities are responsible for the elevator stopping, leading them to take hostages?
answer:
Richie.

Passage: In Icons of Rock: An Encyclopedia of the Legends Who Changed Music Forever, Scott Schinder and Andy Schwartz describe the Beatles' musical evolution:
In their initial incarnation as cheerful, wisecracking moptops, the Fab Four revolutionised the sound, style, and attitude of popular music and opened rock and roll's doors to a tidal wave of British rock acts. Their initial impact would have been enough to establish the Beatles as one of their era's most influential cultural forces, but they didn't stop there. Although their initial style was a highly original, irresistibly catchy synthesis of early American rock and roll and R&B, the Beatles spent the rest of the 1960s expanding rock's stylistic frontiers, consistently staking out new musical territory on each release. The band's increasingly sophisticated experimentation encompassed a variety of genres, including folk-rock, country, psychedelia, and baroque pop, without sacrificing the effortless mass appeal of their early work.
In The Beatles as Musicians, Walter Everett describes Lennon and McCartney's contrasting motivations and approaches to composition: "McCartney may be said to have constantly developed – as a means to entertain – a focused musical talent with an ear for counterpoint and other aspects of craft in the demonstration of a universally agreed-upon common language that he did much to enrich. Conversely, Lennon's mature music is best appreciated as the daring product of a largely unconscious, searching but undisciplined artistic sensibility."Ian MacDonald describes McCartney as "a natural melodist – a creator of tunes capable of existing apart from their harmony". His melody lines are characterised as primarily "vertical", employing wide, consonant intervals which express his "extrovert energy and optimism". Conversely, Lennon's "sedentary, ironic personality" is reflected in a "horizontal" approach featuring minimal, dissonant intervals and repetitive melodies which rely on their harmonic accompaniment for interest: "Basically a realist, he instinctively kept his melodies close to the rhythms and cadences of speech, colouring his lyrics with bluesy tone and harmony rather than creating tunes that made striking shapes of their own." MacDonald praises Harrison's lead guitar work for the role his "characterful lines and textural colourings" play in supporting Lennon and McCartney's parts, and describes Starr as "the father of modern pop/rock drumming". 
Question: What band was referred to as the Fab Four?
answer:

the Beatles.
