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 two main requirements of an anti-torque system are that it should prevent rotation of the sonde, and it should allow easy movement of the drill up and down the borehole. Attempts have been made to design drills with counter-rotating components so that overall torque is minimized, but these have had limited success. Five kinds of anti-torque systems have been devised for use with cable-suspended EM drills, though not all are in current use, and some drills have used a combination of more than one design. The first drill to require an anti-torque system was used at Camp Century by CRREL in 1966; the drill incorporated a set of hinged friction blades that swung out from the sonde when the drill motor was started. These were found to have very weak friction against the borehole wall, and were ineffective; the drill had to be controlled carefully to prevent twisting the cable. No other drills have attempted to use this approach.For the next deployment of the drill leaf springs were installed, and this has proved to be a more durable design. These are mounted vertically, with a curve outwards so that they are easily compressed by the borehole wall, and can slide up and down with the movement of the drill. They pass easily through any areas of irregularity in the borehole, but the edges of the springs cut into the borehole wall and prevent rotation. Leaf springs are very simple mechanically, with the additional benefit of being easy to adjust by changing the spacing between the end points. They can be placed anywhere on the drill that does not rotate, so they do not add length to the sonde. The shape is usually a fourth-order parabola, since this has been determined to provide the most even loading against the borehole wall. Leaf springs have been found to be so effective that they can prevent rotation even in heavy drills running at full power.Skate antitorque systems have blades attached to vertical bars which are pushed against the borehole wall; the blades dig into the wall and provide the anti-torque. Skates can be built with springs which allow them to keep the blades pressed against the wall in an irregular borehole, and to prevent problems in narrower parts of the borehole. Although skates are a popular design for anti-torque and have been used with success, they have difficulty preventing rotation in firn and at boundaries between layers of different densities, and can cause problems when drilling with high torque. When they fail, they act as reamers, removing chips from the wall which can fall to the drillbit and interfere with drilling.
[A]: What acts as reamers when they fail?

[Q]: Passage: Daphne Blake is a high school student who has a semi-popular web show discussing the possibility of aliens and supernatural occurrences. Velma Dinkley is Daphne's supportive yet critical online friend, who believes there is a logical explanation for everything. After Velma web chats Daphne following her latest episode, she reveals to Velma that her parents will be moving to Ridge Valley, where Velma currently goes to high school.
After having a perfect morning at home, Daphne embarks on her first day at Ridge Valley High. She quickly meets Carol, her senior advisor, who shows her the school's expansive collection of advanced technology from Bloom Innovative, a famous technology company. While on her tour, Daphne runs into Velma, who does not speak to her. Later that afternoon, Daphne sees a student named Spencer walk into an open locker as if he were in a trance.
At home, Daphne's father reveals that he has sheltered Daphne all her life, going to extreme lengths to follow her around everywhere in an attempt to make Daphne's life "perfect". Shocked and frustrated at her father, Daphne vows to do everything on her own without her father's assistance. The next day, Daphne gets into a heated argument with Velma over their science project, which Velma intentionally sabotaged. The argument results in the girls getting sent to the principal's office, who puts them on "the best couch for conflict resolution". The couch helps the girls put aside their differences, and Velma reveals she was protecting Daphne because she knew of the strange happenings at the school. Daphne and Velma vow to solve the mystery of the disappearing students.
[A]: What are the full names of the friends who go to Ridge Valley High?

[Q]: Passage: Beth is becoming bored with her life in Florida, doing stripteases and lap dances for private customers. Her dad, Jerry, tells her to follow her dream of moving to Las Vegas, where she seeks honest work as a cocktail waitress.
A young woman named Holly, who lives at the same Vegas motel, arranges for Beth to meet Dink Heimowitz, a professional gambler who follows the fast-changing odds on sporting events and employs assistants at Dink, Inc., to lay big-money bets for him. Beth is intrigued and it turns out she has a good mind for numbers, easily grasping Dink's system and becoming his protegee and he views her as his lucky charm. When Beth begins expressing a more personal interest in her much-older mentor, Dink's sharp-tongued wife, Tulip, lets it be known in no uncertain terms that she wants Beth out of her husband's life. As a result, from pressure from his wife, Dink lets Beth go.
A young journalist from New York, Jeremy, meets Beth in the casino and they immediately hit it off and she makes plans to move back to New York with him, having nothing left in Las Vegas to keep her there. She is hooked on the excitement and income that gambling provides and backs out suddenly whenever Dink, facing a heavy losing streak without his lucky charm, asks her to come back to work for him.
Whenever Dink's losing streak continues even with Beth's return, he has a meltdown and fires everyone in his office. Having enough, Beth goes to New York to be with Jeremy but accepts a similar job for a rival bookie called Rosie. Gambling is illegal in New York and Dink worries about Beth. Rosie then sets up a legal operation based in Curacao and Beth goes down to help run the betting. Rosie and his men are more interested in drugs and hookers and Beth wants out. A New York gambler, Dave Greenberg, is in debt for sixty-thousand dollars and may be working for the Feds.
