TASK DEFINITION: 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.
PROBLEM: Passage: Miklo is a man of Mexican and White American ethnicity who grew up in El Pico Aliso barrio in east Los Angeles. Upon moving back home from Las Vegas, Nevada, Miklo goes to stay with his two cousins Paco and Cruz. Miklo tells Cruz that he wants to join their gang Vatos Locos. While Paco is initially skeptical, Miklo later proves himself when he performs an attack on a rival gang, Tres Puntos. Afterwards he is made a member of Vatos Locos.
However, the Tres Puntos gang soon takes revenge by brutally attacking Cruz who is a budding artist, and damages his back for life. When Vatos Locos learn of the attack, they perform a well-planned counterattack. However, things go wrong when Miklo ends up getting shot by their rival gang's leader, "Spider". Miklo is able to shoot and kill Spider, but has to be rushed to the hospital by Paco while being chased by police. Paco crashes into another car at the El Pino tree and they are both arrested.
From here, the trio's paths diverges: Miklo is sent to San Quentin State Prison for murder, Paco volunteers for military service in the United States Marine Corps as an alternative choice to prison, and Cruz continues his passion for art. He also becomes a heroin addict due to the recurring back pain. His addiction leads to him being disowned by his family after his 12-year-old brother, Juanito, sees Cruz's needle next to him while he is passed out and naively decides to inject himself with it and dies from an overdose.  Paco becomes an L.A.P.D. narcotics detective after leaving the Marine Corps.

SOLUTION: Whose back is damaged for life?

PROBLEM: 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.

SOLUTION: What acts as reamers when they fail?

PROBLEM: Passage: Tim and Susan Gates are eager to move into their new house with their teenage son Shane and their younger son Taylor, as well as their college-bound daughter Kayla, despite the house's dark history of drowned children and foreclosure. As they settle into the house, strange things frequently occur, like the garbage cans being taken out for collection without explanation. While Kayla and her boyfriend Derek are sorting out items for a garage sale, the garage door inexplicably opens and closes. 
The next day, the ladder from the crawlspace descends into view, and the house's previous owner Aldon Webber climbs down. He washes up and helps himself to some food, and he retrieves a stuffed unicorn that Kayla had thrown out. Webber's intrusions into the Gates' lives grow more elaborate and sinister as the film progresses. He watches them closely through the air vents, and he even creeps into Kayla's room one night to film her sleeping. 
The Gates' elderly neighbor warns Kayla and Shane that they need to get out of the house. She has witnessed Webber moving around when the family is gone during the day. After her warning, Webber sneaks into the neighbor's house and attacks her. He stuffs her vacuum cleaner's hose extension into her mouth and then reverses the air flow, emptying the vacuum's contents down her throat. 
Webber's next victim is Taylor's babysitter, who was not watching as the boy played with Shane's paintball gun. At the garage sale, Webber reveals himself to Kayla and Shane, but poses as a customer. When Webber does not leave after the sale is over, Shane approaches him aggressively. Webber punches Shane in the face and walks off the property.

SOLUTION:
Who does Aldon Webber kill first?
