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: Mark Bradley is a radio commentator whose pilot, Joe Walker, is flying him across the South Pacific to a conference in Australia. 
Engine trouble develops, and Walker must make a forced landing on the beach of a small, uncharted island inhabited by Dr. Paul Lujan. On the island with Lujan are his three naive daughters, who have never known another man except their father. 
Lujan, unfriendly to the point of hostility, orders the intruders to leave his island, but one of their aircraft's two engines is too badly damaged for them to be able to comply without first making repairs. He grants them a couple days in order to do so. In the meantime he grudgingly introduces Bradley and Walker to his trio of young, beautiful daughters, Venus, Urana, and Mercuria. The two men soon learn that Dr. Lujan was an atomic scientist who fled the civilized world with his family because he fears the havoc being caused by the discovery of nuclear energy.
To the doctor's disapproval, his two older daughters easily fall in love with the two attractive strangers and try to help them, while the third, 16 and jealous of her sisters, tries to foil their plans. This forces them to make a choice between staying on the island with their father or returning with the two men to a civilization they have only experienced via short wave radio broadcasts. When Bradley mentions that he plans on doing a radio broadcast about Lujan and his island location after he returns to civilization, the Dr. begins to scheme a way to keep the men and his daughters on the island.

SOLUTION: What is the full name of the person being flown across the South Pacific?

PROBLEM: Passage: An inventory of medium and large mammals in the park confirmed the presence of 30 species in Saguaro National Park between 1999 and 2008. Of these, 21 were found in the Tucson Mountain District and 29 in the Rincon Mountain District. A partial list of the park's mammals includes cougars, coyotes, bobcats, white-tailed deer, mule deer, javelinas, gray foxes, black-tailed jackrabbits, desert cottontails, ring-tailed cats, white-nosed coatis, ground squirrels, and packrats. One endangered mammal, the lesser long-nosed bat, lives part of the year in the park and part of the year in Mexico.The wide range of habitats in the park supports a diverse population of birds including some, such as the vermilion flycatcher and the whiskered screech owl, uncommon elsewhere in the United States. Among the park's 107 bird species are great horned owls, cactus wrens, ravens, kestrels, turkey vultures, roadrunners, woodpeckers, hawks, quails, and hummingbirds, and one threatened species, the Mexican spotted owl.The park's 36 reptile species include desert tortoises, diamondback rattlesnakes (one of the more commonly seen snakes), coral snakes, Gila monsters, short-horned lizards, spiny lizards, and zebra-tailed lizards. Despite the aridity, three amphibian species inhabit the park: the canyon tree frog, the lowland leopard frog, and Couch's spadefoot, which lives in underground burrows, emerging to breed during summer rains. Forest fires, which create erosion-prone burned areas, have destroyed many of the leopard frog's breeding pools, which fill with sediment. The Arizona Game and Fish Department lists the lowland leopard frog as a species of special concern.Urban sprawl, air and water pollution, noise, light pollution, and a range of habitat restricted by human infrastructure put stress on the park's mammals and other animals, but the most serious immediate threat to them is roadkill. About 50,000 vertebrates a year die on the park's roads when they are hit by a vehicle. The Rincon Mountain District has few roads, but Picture Rocks Road, an east–west commuter highway crossing the Tucson Mountain District, is highly dangerous to wildlife. Attempts in 2002 to convert it to a hiking trail failed after the proposal met with stiff public resistance.

SOLUTION: What was attempted to be converted into a hiking trail?

PROBLEM: Passage: The story begins in the 1960s with three inmates in a New York prison — Earl, Rocco, and Carlito — controlling their criminal empire within their cell. Upon their release, they all look to control the drug trade in Harlem, which is currently in a power dispute between the Italian Bottolota crime family and black gangsters led by Hollywood Nicky. Rocco takes them to Artie Bottolota who at first is reluctant to work with blacks and Puerto Ricans, but who eventually cuts a deal with them in heroin distribution. The friends also meet Artie's son, Artie Jr. Soon, Earl's troubled younger brother Reggie joins them. It does not take long for Reggie to cause trouble; eventually endangering both himself and Carlito's deal with the Bottolotas.
Artie Jr. attempts to kill Reggie with a straight razor, while Carlito is restrained. Rocco pulls up and tells Artie Jr. to let him go, reasoning they will "take care of him." Carlito also meets a young lady named Leticia and meets her brother Sigfredo. Sigfredo knows who and what Carlito really is, which leads to confrontation. Carlito eventually proves himself to Leticia's family, but Sigfredo leaves.
Reggie, after being kicked off the crew by Carlito, attacks and kidnaps Artie Jr. outside of his house, with the help of two other thugs. After Reggie gets the ransom, Artie Jr. is released by police and returns to his family.
The Bottolotta Family blames Carlito, Rocco, and Earl for assisting Reggie in the kidnapping. Artie Sr. puts out a contract on the trio.  The hitman contracted to kill them, Nacho Reyes, and Carlito's accomplice, Colorado help them find the hoodlums with Reggie. Reggie's location is learned.

SOLUTION:
What is the name of the person that Rocco tells Artie Jr. to let go?
