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: Dr. Henry Jekyll, a kind English doctor in Victorian London, is certain that within each man lurks impulses for both good and evil. He is desperately in love with his fiancée Muriel Carew and wants to marry her immediately. But her father, Brigadier General Sir Danvers Carew, orders them to wait. One night, while walking home with his colleague, Dr. John Lanyon, Jekyll spots a bar singer, Ivy Pierson, being attacked by a man outside her boarding house. Jekyll drives the man away and carries Ivy up to her room to attend to her. Ivy tries to seduce Jekyll but, though he is tempted, he leaves with Lanyon.
When Sir Danvers takes Muriel to Bath, Jekyll begins to experiment with drugs that he believes will unleash his evil side. After imbibing a concoction of these drugs, he transforms into Edward Hyde—an impulsive, violent, amoral man who indulges his every desire. Hyde finds Ivy in the music hall where she works. He offers to financially support her in return for her company. They stay at her boarding house where Hyde sexually abuses and psychologically manipulates her. When Hyde reads in the paper that Sir Danvers and Muriel are planning to return to London, Hyde leaves Ivy but threatens her that he'll return when she least expects it.
Overcome with guilt, Jekyll sends £50 to Ivy. On the advice of her landlady, Ivy goes to see Dr. Jekyll and recognizes him as the man who saved her from abuse that night. She tearfully tells him about her situation with Hyde, and Jekyll reassures her that she will never see Hyde again. But the next night, while walking to a party at Muriel's where the wedding date is to be announced, Jekyll spontaneously changes into Hyde. Rather than attend the party, Hyde goes to Ivy's room and murders her.

Q: Passage: A man unveils a valuable painting he picked up for $50,000 and is killed. A card with a large black ace (of spades) is put on his chest. Another "Black Ace" victim. The killer sends his victims a Black Ace card, warning them they are to die and then kills them, his way of taunting the police. Neil Broderick, an author, intends writing a book about him and is on his way to see Thornton Drake to get more information about him. Austin Winters is his secretary and Neil met his daughter Martha on the train, on the way to Chicago.
Drake has just received a Black Ace, with the words: "At seven tomorrow night", the time he is to be killed. Two plainclothes cops arrive from police headquarters, having had a call, Clancy and Dugan (both incompetents). Martha suggests that they leave for Drake's Louisiana plantation tomorrow morning and be far away from there at seven tomorrow night. Drake agrees and suggests they all go. On the flight, the lights go off for some seconds and when they come on again, Austin Winters is dead without a mark on him.
At the plantation, Clancy ineptly questions the suspects till Neil points out that they are now in another state, so out of their jurisdiction. Neil goes to another room and makes a phone call, then signals to someone outside. After he finishes his call, the line is cut. Meanwhile one of the pilots has taken off in the plane, leaving the other pilot, Henderson, behind who claims he does not know anything though he was out of the cockpit when Winters was killed.
The coroner finds a letter on the dead man which is to be read if Winters dies. It will reveal the identity of the Black Ace. Clancy starts reading it aloud and unsurprisingly the lights go off and the letter has vanished when the lights are turned on again. People locked in their rooms that night and Neil has a hidden car outside signal to him.

A: Who is Neil Broderick writing a book about?

Q: Passage: In 2011, a group of soldiers and a  journalist team head out to the jungles of Belize. The mission was thought to just be plant surveillance on hostile state borders. The soldiers and Julie Evans team locate an abandoned boat in the middle of an open field.  One of the soldiers advises Julie that the nearest ocean to where they found the boat is at least 150 miles. A camera with an intact SD card was retrieved from the boat. Footage from the SD card contained underwater footage and ended with a man screaming  as the screen fades to black.
Afterwards, the team decides to make camp and set up security cameras. Night vision cameras show various animals roaming around. One of the cameras suddenly blacks out. At dawn, the soldiers find markings on trees near Julie's sleeping area. They soon discover that a camera - the one that blacked out earlier, was destroyed.
The group soon receives new orders from base. An archaeological team has gone missing. And they are to head to the area where Dr. Holden's archaeological team was last seen. They soon run into a man cutting wood and asks him about the missing archaeological team. He claims to have no idea where they are.
The group arrives at Dr. Holden's camp site. They only find a man who claims to also be looking for Dr. Holden. A video diary belonging to Dr. Holden is then shown. It's shown in the video that Dr. Holden located a mysterious skull inside the cave. Afterwards, a strange sound is heard and the camera woman Susan runs outside the cave panicking.
Julie is then informed that one of the two missing archaeologist has been found and they head to the location. On their way they encounter a Mennonite community. The Mennonites then proceed to show them to where Susan is. Susan claims she knows where Holden is and will take them to where she last saw him. Susan explains that what attacked them was not human. It is then that they experience a strange trembling and Susan claims that it is the same thing that happened to them.
