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.

Example Input: Passage: Medina gets up after hearing a voice in her dreams. She prepares to go out, has a coffee, and does a quick breath relaxation exercise. Her friend, Sidonia, arrives and finds Medina, who is looking at herself in the mirror with a sad expression. Sidonia tries to lighten the moment, and reminds Medina that her friends and family are waiting for her. Medina gets herself together and they head off to the funeral service for Medina's fiancé.
Medina is with her friend Tesla, who tells her she is love with Medina's brother, Enzo, and is thinking of getting engaged. Medina is a bit surprised, but congratulates her. They try to visit an art exhibit, but the female security guard kicks them out, as she remembers the duo's wild reputation. Medine is upset, but Tesla invites her and Enzo for drinks. Tesla and Enzo cheer Medina up with their light conversation.

Quinn looks depressed as he meets up with his friend Fera at the street. He tells her that Nilda left him and took everything, including his possessions. He shows her the "Dear John letter" composed on bath tissue. Fera's husband, Camden, arrives and they explain the situation. Fera and Camden console Quinn but he leaves to clear his mind. They follow Quinn to make sure he does not do something regretful.
Tesla reminds Medina of an upcoming martial arts promotion test. Medina prepares by doing some stretching, practicing footwork, and twirling weapons including swords, staffs and spears. Meanwhile, Fera is increasingly concerned about Quinn. Camden notes that Fera and Quinn act like siblings, but for now, all they can do is continue to look after Quinn. They head to a show at the Lincoln Center.
Example Output: Who wrote Quinn a Dear John Letter?

Example Input: Passage: There are over 40 species of mammals in the Pine Creek Gorge. Leonard Harrison State Park's extensive forest cover makes it a habitat for "big woods" wildlife, including white-tailed deer, black bear, wild turkey, red and gray squirrels. Less common creatures include bobcats, coyote, fishers, river otters, and timber rattlesnakes. There are over 26 species of fish in Pine Creek, including trout, suckers, fallfish, and rock bass. Other aquatic species include crayfish and frogs.Several species have been reintroduced to the gorge. White-tailed deer were imported from Michigan and released throughout Pennsylvania to reestablish what had once been a thriving population. The current population of deer in Pennsylvania are descended from the original stock introduced beginning in 1906, after the lumberman had moved out of the area. The deer population has grown so much that today they exceed their carrying capacity in many areas. River otters were successfully reintroduced in 1983 and now breed in the gorge. Despite the fears of anglers, their diet is only 5 percent trout.Fishers, medium-sized weasels, were reintroduced to Pine Creek Gorge as part of an effort to establish a healthy population of fishers in Pennsylvania. Prior to the lumber era, fishers were numerous throughout the forests of Pennsylvania. They are generalized predators and will hunt any smaller creatures in their territory, including porcupines. Elk have been reintroduced west of the gorge in Clinton County and occasionally wander near the west rim of the canyon. Coyotes have come back on their own. Invasive insect species in the gorge include gypsy moths, which eat all the leaves off trees, especially oaks, and hemlock woolly adelgids, which weaken and kill hemlocks. Invasive plant species include purple loosestrife and Japanese knotweed.
Example Output: What is the full name of the place that have had several species reintroduced?

Example Input: 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.
Example Output:
What acts as reamers when they fail?
