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.

[EX Q]: Passage: The film focuses on the cast and crew of a new TV series called Manhattan, which is shot on location in New York City. Mel Wexler is a successful producer who has become a workaholic since the death of his family in a plane crash. Trying to forget his loss, he throws himself on producing Manhattan. For the lead role, he tries to cast the feared film star Sabina Quarles, who has a reputation of being hard to work with. She initially declines, explaining she is too good for television. However, because of her past with Mel, she finally accepts the role. They soon start a relationship, but he remains suspicious of her constant visits to San Francisco. She is reluctant to explain why she is going there every month, which makes him think she has an affair.
Meanwhile, playing her stepson in the series is Bill Warwick, an actor who is a sex symbol. He is married to Sandy, but because of his image, he has to keep their marriage a secret. Sandy was once a great actress, but her drug addiction has turned her into a street prostitute, ignoring her work. He thinks a co-starring role could help her going towards the right path, but she fails to show up at her audition. The role eventually goes to Gaby Smith, a rich actress who graduated from Yale. From the very beginning, Bill is upset that his wife wasn't given the role and as a result, treats Gaby very badly. This makes her very sad, constantly trying to win his trust over.
[EX A]: What does Sandy do to make Bill keep their marriage secret?

[EX Q]: 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.
[EX A]: What was attempted to be converted into a hiking trail?

[EX Q]: Passage: In Sydney, Australia, a puppy named Muffin is living with a human family and his own mother. Muffin, calling himself Napoleon and pretending to be tough, wishes that he could live with the wild dogs that he can hear howling in the distance. The family has a birthday party and one of the decorations is a basket with balloons strapped to it. Out of curiosity, Napoleon hops inside, but the basket, untied from its tether, begins to float away.
Napoleon flies high above the city and heads out to the sea. A galah named Birdo drops down on the side of his basket and offers to help him get down. Birdo's idea of help is to pop the balloons suspending the basket, causing Napoleon to land unharmed on a beachhead. Napoleon thinks he can finally seek out the wild dogs and heads into a nearby forest, ignoring Birdo's suggestion to return home.
At night, Napoleon starts to fear being alone. A mopoke in the forest warns Napoleon of terrible things that can happen to pets in the wild, but Napoleon ignores him as well and continues on his way. He discovers a large tree used by a psychotic cat as a home. The cat spots Napoleon and, thinking he is a mouse, chases him. Napoleon escapes when the mopoke pushes the cat into a pond. The mopoke then warns Napoleon that the cat will not rest until he is dead. As Napoleon runs off, the cat pulls herself from the pond angrily swearing revenge.
The next morning, Napoleon once again encounters Birdo, who decides to teach Napoleon how to live in the wild.
[EX A]:
What does Napoleon's human family call him?
