Passage: Frank Chambers a drifter, stops at a depression-era rural California diner for a meal and ends up working there. The diner is operated by a young, beautiful woman, Cora Smith, and her much older husband, Nick Papadakis, a hardworking but unimaginative immigrant from Greece.
Frank and Cora start to have an affair soon after they meet. Cora is tired of her situation, married to an older man she does not love, and working at a diner that she wishes to own and improve. She and Frank scheme to murder Nick to start a new life together without her losing the diner. Their first attempt at the murder is a failure, but Nick is not even aware they tried to kill him, so goes about living his life as usual. Frank and Cora succeed with their next attempt.
The local prosecutor suspects what has actually occurred but does not have enough evidence to prove it. As a tactic intended to get Cora and Frank to turn on one another, he tries only Cora for the crime.
Although they turn against each other, a clever ploy from Cora's lawyer, Katz, prevents Cora's full confession from coming into the hands of the prosecutor. With the tactic having failed to generate any new evidence for the prosecution, Cora benefits from a deal in which she pleads guilty to manslaughter and is sentenced to probation.
Months later, Frank has an affair with Madge Gorland while Cora is out of town. When Cora returns, she tells Frank she is pregnant. That night, Katz's assistant, Kennedy, appears at their door and threatens to expose them unless they give him $10,000. Enraged, Frank beats Kennedy up and strong-arms him into giving up the evidence against them. 
Question: What are the last names of the people who are planning to murder Nick?

Ex Output:
Smith.

Passage: The Covent Garden area has over 60 pubs and bars; several of them are listed buildings, with some also on CAMRA's National Inventory of Historic Pub Interiors; some, such as The Harp in Chandos Place, have received consumer awards. The Harp's awards include London Pub of the Year in 2008 by the Society for the Preservation of Beers from the Wood, and National Pub of the Year by CAMRA in 2010. It was at one time owned by the Charrington Brewery, when it was known as The Welsh Harp; in 1995 the name was abbreviated to just The Harp, before Charrington sold it to Punch Taverns in 1997. It was eventually purchased by the landlady Binnie Walsh around 2010 then subsequently sold by her to Fuller's Brewery in 2014.  It continues to win regular CAMRA pub awards under its new owners.
The Lamb and Flag in Rose Street is possibly the oldest pub in the area. The first mention of a pub on the site is 1772 (when it was called the Cooper's Arms – the name changing to Lamb & Flag in 1833); the 1958 brick exterior conceals what may be an early 18th-century frame of a house replacing the original one built in 1638. The pub acquired a reputation for staging bare-knuckle prize fights during the early 19th century when it earned the nickname "Bucket of Blood". The alleyway beside the pub was the scene of an attack on John Dryden in 1679 by thugs hired by John Wilmot, 2nd Earl of Rochester, with whom he had a long-standing conflict.The Salisbury in St Martin's Lane was built as part of a six-storey block around 1899 on the site of an earlier pub that had been known under several names, including the Coach & Horses and Ben Caunt's Head; it is both Grade II listed, and on CAMRA's National Inventory, due to the quality of the etched and polished glass and the carved woodwork, summed up as "good fin de siècle ensemble". The Freemasons Arms on Long Acre is linked with the founding of the Football Association in 1863; however, the meetings took place at The Freemason's Tavern on Great Queen Street, which was replaced in 1909 by the Connaught Rooms.Other Grade II listed pubs include three 19th century rebuilds of 17th century/18th century houses, the Nell Gwynne Tavern in Bull Inn Court, the Nag's Head on James Street, and the White Swan on New Row; a Victorian pub built by lessees of the Marquis of Exeter, the Old Bell on the corner of Exeter Street and Wellington Street; and a late 18th or early 19th century pub the Angel and Crown on St Martin's Lane. 
Question: What is the current name of the pub that acquired a reputation for staging bare-knuckle prize fights?

Ex Output:
Lamb and Flag.

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: What is the last name of the person who sentences someone to lifelong slavery?

Ex Output:

Pilate.
