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.

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.

Passage: Collin Hoskins, a convicted felon, is struggling to finish the last three days of his probation. Collin, along with his short-tempered best friend Miles Turner, works for a moving company located in Oakland, a city in the Bay Area. One night while waiting for a red light, Collin witnesses a white police officer gun down a black civilian. As Collin is haunted by the incident, he begins to have nightmares and experiences hallucinations. 
At the same time, Miles becomes distraught by the gentrification of Oakland, and a resulting sense of loss of identity, home, and belonging.  
Miles purchases a gun from a friend on the basis of self-protection, an action which Collin strongly disapproves. As Miles continues to display erratic behavior, Collin's ex-girlfriend Val warns Collin of the dangers that may come from a continued friendship with Miles. Later that evening while having dinner, Miles' gun accidentally ends up in the hands of his young son Sean, an incident which horrifies Sean's mother Ashley, forcing both Collin and Miles to leave the house. At a party, an agitated Miles assaults a black man who misinterpreted Miles' persona as cultural appropriation, leading to a fight between the two. Miles uses his gun to terrorize the party guests before being stopped by Collin. In an explosive argument, Collin criticizes Miles for his reckless behavior and the trouble it keeps causing him.

Passage: A group of puppies are stolen from a pet store by two thieves. A St. Bernard puppy escapes and sneaks into the Newton family's home. The workaholic father, George Newton, doesn't want the responsibility of owning a dog, but his wife, Alice, and their children, Ryce, Ted, and Emily, convince him. They give him the name "Beethoven" when Emily plays a portion of Ludwig van Beethoven's Fifth Symphony on the piano and the dog barks along to it.
Beethoven grows into an extremely fat adult dog and helps the children overcome their problems: he helps Ryce talk to her crush, scares off bullies for Ted, and saves Emily's life when she falls into an irresponsible babysitter's swimming pool. George, jealous of the affection Beethoven receives, feels neglected as his family fawns over him. His antics ruin a barbecue he is hosting for Brad and Brie, rude, unpleasant venture capitalists looking to invest in and secretly swindle him out of his car freshener firm.
The Newtons take Beethoven to a veterinarian, Dr. Herman Varnick, for a routine medical examination and immunizations. They are unaware that he is involved in unethical and deadly animal experimentation. He speaks to George and tells him of a supposed mental instability among St. Bernards making them potentially dangerous to humans and advises him to watch Beethoven closely for any sign of viciousness. He actually requires large-skulled dogs such as St. Bernards for an ammunition test.

Ex Output:
