instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
question:
Passage: The blacksmith and swordsmith John is tutored at the court of King Arthur, but as a commoner he can't hope to win the hand of Lady Linet, daughter of the Earl of Yeonil. The Earl's castle is attacked by Saracens and Cornishmen — disguised as Vikings — and his wife is killed, making him lose his memory. The attack was part of a plot by the Saracen Sir Palamides and the pagan Cornish King Mark to overthrow Arthur and Christianity and take over the country, whilst pretending to be Arthur's friends and allies  - Palamides is a knight of the round table and Mark has faked his own baptism.John accuses Palamides' servant Bernard of murder before Arthur, who grants him three months' grace to prove the accusation or face execution himself. Another knight, Sir Ontzlake, takes pity on John and trains him in swordplay so that he can take on an alternative secret identity as the wandering Black Knight. The "Vikings" raid a newly founded monastery and take Lady Linet and its monks to Stonehenge for a pagan sacrifice, but the Black Knight arrives and saves her, closely followed by Arthur and his knights, who defeat the pagans and destroy Stonehenge.
Sir Palamides tricks the Lady Linet into his castle to try to get her to reveal the Black Knight's identity, but John is informed of this and saves her, still in disguise. Sir Ontzlake then sends him to King Mark's castle, where a pro-Arthur woodcarver shows him  a secret tunnel into the royal chambers. John arrives in time to overhear Mark and Palamides finalising their plot but Palamides beats him back to Camelot, tricking Arthur into thinking that the Black Knight is leading the Viking raids. John arrives dressed as the Black Knight and despite revealing his identity is briefly imprisoned until Lady Linet and Sir Ontzlake free him, with the latter standing bail for John to Arthur.
answer:
Who loses his memory after his wife is killed?

Passage: The album appeared in numerous publication's lists of best albums of 2000. It appeared at number nine on Kerrang!'s list of albums of the year, and went on to rate it the 11th best album of the 2000–2009 decade, while NME ranked it at number 34 in their critic's pick of the 50 best albums of 2000 in their "Decade in Music" series. German magazine Musik Express/Sounds listed the album at number 30 in their critics' top 50, and at number nine in the popular poll of their "Albums of 2000" list. The French edition of British magazine Rock Sound ranked Holy Wood 15th in their Le choix de la rédaction (editors choice) and 5th in Le choix des lecteurs (readers choice) of their 2000 Albums de l'année (albums of the year). Record Collector also included it on their "Best of 2000" list. It went on to win the "Best Album" accolade at the 2001 Kerrang! Awards.Retrospective commentary on the album has been highly positive. In November 2010, Kerrang! published a tenth-anniversary commemorative issue dedicated to Holy Wood titled Screaming For Vengeance, calling it "Manson's finest hour". In 2014, Metal Hammer identified the album as a modern classic, calling it the band's "creative zenith". Manson said in a June 2015 Reddit AMA that he considered the record to be his best work, and, that same month, NME referred to it as the band's best album. A 2016 feature in Houston Press called Holy Wood "the album that really cemented the band as more than just shock-rockers, but true musical mavericks with an intelligent perspective on social issues." Metal Hammer referred to the record as "perfect", saying: "Manson has yet to better Holy Wood and that's fine—nobody's really bettered it. The flow of the record, the delivery of its concept, the clarity with which it strikes its opponents. A gargantuan artistic feat that will go down in history as Manson's defining statement.".
answer:
What is the last name of the artist who recorded the album?


question:
Passage: Ryker, a former mercenary, comes out of retirement to take part in the overthrow of an African dictator. He travels to London to meet former war comrade Jesse Jones, and his associates Freddy Bradshaw and Temple Smith. After helping fellow mercenaries test and ship weapons to South Africa, Ryker begins to have ethical concerns about his involvement. He eventually distances himself from the others, and rents a flat in London. He falls into hippie culture, and begins dating a girl named Chrissie.
Jesse tracks down Ryker. Explaining that the operation is not producing the profits he expected, he tries to convince Ryker to return. Ryker declines, but develops a plan with Jesse to thwart the operation and take the money for themselves. They succeed and escape with Bradshaw's car. A weapons dealer named Rawlings pursues them.
Jesse discovers that their "take" is somewhat less than the amount of cash they supposedly embezzled. Ryker reveals that his real plan was to sabotage the gun running operation, not to take all the money. Jesse assaults Ryker; Ryker, now a pacifist, refuses to defend himself. Ryker is eventually forced to break Jesse's ankle to end his assault. As Ryker bundles Jesse into a car to seek medical treatment, Rawlings shoots them down with rifle fire.
answer:

Who traveled to London?
