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.

Q: 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.

Q: Passage: Dr. Watson is serving as resident doctor at Musgrave Manor in Northumberland, a stately home which is also used as a hospital for a number of servicemen suffering from shell shock.When Sally Musgrave displays her feelings for one of the wounded American fighter pilots, Captain Pat Vickery, who is currently recovering at the family estate, her brothers Geoffrey and Phillip are quick to show their dismay.
Then one of the physicians working at the estate, Dr. Sexton, is assaulted by an unknown assailant when out on a walk. Dr. John Watson, who is in charge of the medical facility, goes to fetch his dear friend Sherlock Holmes to bring some clarity to the case of the attack.
Upon his arrival to the estate, Sherlock Holmes discovers the dead body of one of the brothers, Geoffrey. Inspector Lestrade of the Scotland Yard is put on the case to solve the murder, and immediately arrests the captain as a suspect.
Holmes is of another opinion about the flyer's guilt and continues to investigate on his own.  Phillip is formally made the new head of the estate the next day with the aid of his sister.  But after only one day of ruling the estate, Phillip too is found murdered, lying in the trunk of the car.
Lestrade suspects the family butler, Alfred Brunton, to be the murderer because Phillip had just fired the butler. Trying to arrest the butler, Lestrade gets lost in the manor's secret passageways. Meanwhile Holmes and Watson look into the special "Musgrave Ritual" that the family uses to appoint the new head of the family. They find the words used in the ritual hidden in Sally's room and try to copy the ritual, which involves replaying a giant chess game on the checkered floor of the house main hall. As pieces in the game they use the household staff.

A: Who fired the butler before the crimes were committed?

Q: Passage: After several years having focused entirely on his career with the Regional Information Service, Jaojoby was approached in 1987 by Frenchman Pierre Henri Donat to contribute several recordings to Madagascar's first salegy compilation album, Les Grands Maîtres du Salegy ("Grand Masters of Salegy"). The runaway success of one of the tracks he composed and performed, "Samy Mandeha Samy Mitady", elevated salegy from a regional genre to one of nationwide popularity, leading a newspaper to declare him the "King of Salegy". High demand for live performances led the singer to return to Antananarivo in 1988 to form a band named "Jaojoby" that included former bandmates from Los Matadores and The Players. Jaojoby begin touring regularly at home and abroad, performing his first international concerts in Paris in 1989. In the meantime, he worked as a press attaché for the Ministry of Transport, Meteorology and Tourism from 1990 until 1993, at which point he left his job to become a full-time musician.The 1992 release of Jaojoby's first full-length album, titled Salegy!, was facilitated by fRoots magazine editor Ian Anderson, who had worked with Jaojoby to record several of his tracks for a radio broadcast two years previously. Jaojoby's second album, Velono, was the first salegy album to be recorded in France, as well as the first of his albums to be produced in a professional-quality recording studio. Following the 1994 release of Velono, Jaojoby became a regular on the international music festival circuit and has performed at such events as WOMAD in Reading, the Festival du Bout du Monde in Brittany, WOMEX in Spain, the Festival des Musiques Métisses in Angoulême, the MASA Festival in Abidjan, and similar events in Germany, the Netherlands, and Portugal. Jaojoby's excitement over his rise to international celebrity was attenuated by the 1995 death of the band's original drummer, Jean-Claude Djaonarana, who had first performed with Jaojoby as a member of Los Matadores.

A:
