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: Worlds End State Park is a 780-acre (316 ha) Pennsylvania state park in Sullivan County, Pennsylvania, in the United States. The park, nearly surrounded by Loyalsock State Forest, is in the Loyalsock Creek valley on Pennsylvania Route 154, in Forks and Shrewsbury Townships southeast of the borough of Forksville. The name Worlds End has been used since at least 1872, but its origins are uncertain. Although it was founded as Worlds End State Forest Park by Governor Gifford Pinchot in 1932, the park was officially known as Whirls End State Forest Park from 1936 to 1943.The park's land was once home to Native Americans, followed by settlers who cleared the forests for subsistence farming and later built sawmills. The second growth forests in and surrounding Worlds End State Park are partially a result of the efforts of the young men of the Civilian Conservation Corps during the Great Depression. They helped overcome the clearcutting of the early 20th century, and built many of the park's facilities, including the cabins that earned it a place on the National Register of Historic Places.
A wide variety of wildlife is found in the park, which is also part of an Important Bird Area. Located in the Endless Mountains region of the dissected Allegheny Plateau, Worlds End has a continental climate and rocks and fossils from the Carboniferous period. It is one of "Twenty Must-See Pennsylvania State Parks" named by the Pennsylvania Department of Conservation and Natural Resources, which describes it as "[v]irtually in a class by itself, this wild, rugged and rustic area seems almost untamed". The park offers year-round recreational opportunities, including environmental education, hiking, camping in tents and cabins, whitewater rafting, swimming, cross-country skiing, snowmobiling, hunting, and fishing.

SOLUTION: What is the precise modern-day name of the park whose land was once home to Native Americans, followed by settlers who cleared the forests for subsistence farming and later built sawmills?

PROBLEM: Passage: The film is set in the home of a mad scientist called Professor Noodle. Professor Noodle has just developed a rejuvenation solution that reverses the aging process. Stan and Oliver are chimney sweeps and arrive to sweep the chimney. Oliver goes on to the roof and Stan stays below at the fireplace. Stan begins to shove the sweep up the chimney and knocks Oliver backwards and down through the skylight. Oliver comes back on to the roof and begins to pull the sweep up. Stan has hung on to the sweep and arrives at the roof. Oliver drops him back down through the chimney. Stan doesn't have enough extensions for the sweep and decides to use a rifle to shove the sweep the last part of the way. The gun goes off nearly shooting Oliver. Stan decides to go up to the roof and as he opens the skylight he knocks Oliver off the roof and down onto a greenhouse. Hardy finally falls down the chimney dislodging many bricks, sending a cloud of soot all over the living room and onto the butler, and damaging the piano. The butler says something about an electric chair, and stalks out. Stan and Oliver start to clean up the soot around the fireplace. They become distracted and Stan shovels the soot into Oliver's trousers.
Professor Noodle decides to test his rejuvenation solution. He puts a duck in a vat of water and adds a drop of his solution. The duck turns into a duckling. The professor is excited and decides to show Stan and Oliver his discovery. He puts another drop of his solution into the vat and the duckling turns into an egg. Stan and Oliver decide to test the solution for themselves when the professor leaves the room to fetch and rejuvenate the butler. Stan accidentally knocks Oliver and the solution into the vat. Oliver emerges as a chimpanzee. Despite being rejuvenated—de-evolved, even—into a chimp by the massive overdose of the solution, he is able to say what he has said multiple times throughout, "I have nothing to say".

SOLUTION: What does the person who became a chimpanzee do for a living?

PROBLEM: Passage: The film is set in a post-apocalyptic future, where Earth's atmosphere has become toxic. Most humans have fled the planet, to live on a space station near Io, a moon of Jupiter. 
Sam Walden is one of the few humans remaining on Earth. She lives alone at high altitude, where the air is still breathable, trying to raise bees that can survive in the atmosphere. Her intent is to use the bees to eventually clean the air via the pollinization of oxygen-producing plants. Her long-distance boyfriend, who lives on the Io station, urges her to leave Earth on the last shuttle from the planet.
A storm creates a toxic cloud that passes through Sam's shelter, apparently killing all of her bees. Micah, a man travelling by helium balloon, arrives shortly thereafter. He intends to reach the launch site and leave Earth, but first wants to speak with Dr. Harry Walden, Sam's father, who had urged mankind to stay because he still saw hope. 
Initially, Sam states that her father is conducting field work elsewhere. However, after a day, she reveals that her father died the previous year. Hearing this, Micah is determined to take Sam with him to the space shuttle, to which she apathetically agrees. After receiving a message from her boyfriend saying goodbye, because he is part of an expedition embarking on a 10-year voyage to an exoplanet orbiting Alpha Centauri, Sam records a message informing everyone still on Earth that Dr. Walden's attempt to clean the planet was ultimately unsuccessful and that everybody should leave to Io.

SOLUTION:
Who convinces Dr. Walden's daughter to leave Earth?
