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 crew of a malfunctioning alien cargo ship make an emergency landing on Earth. This draws the attention of four sexually-frustrated humans in a nearby park: Oliver and Prudence (a mild-mannered professional and his highly-strung fiancée), Willy (a bumbling shop assistant) and Cliff (a middle-aged man).
Oliver, Prudence, Willy and Cliff wander into the ship and encounter three aliens resembling human women: engineer Partha, nurse Cosia and the captain, known only as Skipper. Willy inadvertently drops some pornographic magazines that he has recently bought. The aliens mistake some approaching cows for a hostile force and hurriedly take off, despite warnings from the long-suffering computer about the precarious state of the ship's systems. Resuming their original course, they study their guests in detail. Fascinated by the anatomy of the males, they decide to sell them to a zoo for exotic lifeforms on a distant planet. They also debate the significance of the acts depicted in Willy's magazines. Partha is particularly keen to emulate them and enthusiastically has sex with Cliff.
Skipper, Cosia and Partha subject the males to a series of tests to learn more about their abilities. Oliver and Cliff fail miserably. However, Willy, looking for his magazines, beats Skipper's combat simulation by unknowingly evading her attacks, causing her to collapse with exhaustion and infer that he is a stronger being. While conducting a physical examination on Willy, Cosia discovers that his biology is more advanced than anything known to their species; encouraging Cosia with exaggerated claims about his sexual prowess, Willy loses his virginity to her. Later, he passes an intelligence test by a fluke and has sex with Partha.
[EX A]: Who mistakes some approaching cows for a hostile force?

[EX Q]: Passage: Three neighborhood teens and childhood friends, Alex, Tuck, and Munch, are upset by the fact that their neighborhood, Mulberry Woods, Nevada, is going to be demolished, allegedly for a new highway construction project, and they all have to move away because of it.
While at Tuck's house, their phones start to glitch out, displaying seemingly random graphical patterns. They soon find out, through Munch, that the patterns are actually a map to a spot in the desert 17.6 miles away. They decide to go to the desert on their bikes and disguise it as a sleepover, recording the experience on various cameras because it's their last night together.
Tuck, Alex, and Munch eventually make it to the desert, and they follow the map to a dusty, rusted object under an electrical tower. Tuck, confused, decides to abruptly call it off when the object starts to copy Alex's ringtone, and they follow another map to a barn. There the object telekinetically starts to repair itself, and the boys find it contains an alien that can answer questions with "Yes" or "No" answers, from which they learn it is from outer space, has crash landed after being shot down by an unknown force, and is seriously injured.
They follow another map to a pawn shop, where the object further repairs itself, allowing the alien to reveal itself, using Alex's phone camera to "see" and befriend the three. While in an alley, they decide to name the alien "Echo." Looking for more parts to repair Echo, they again follow another map to a house where Emma, a girl who goes to their high school, lives and finds out about Echo. Emma soon joins the team, as they go to a bar, then an arcade, and she finds out the object Echo is in is a key to a spaceship hidden in Mulberry Woods.
[EX A]: Who names the alien?

[EX Q]: Passage: Fish found in Shoshone National Forest include at least six species and subspecies of trout  including rainbow, brook and brown trout. The Yellowstone cutthroat trout is widespread throughout the Greater Yellowstone Ecosystem, but in the forest is mostly limited to the Shoshone River. The mountain whitefish is also found in the Shoshone River, while the burbot is found in two streams in the southern regions of the forest.There are more than a dozen species of reptiles in the forest including the venomous prairie rattlesnake which can be found at lower elevations. The western painted and the ornate box turtle are turtle species known to exist and about eight species of lizards such as the greater short-horned lizard have been documented. Amphibians such as the Columbia spotted frog and the boreal toad are considered species of concern because of their high susceptibility to disease, habitat loss and human introduced toxins. Boreal toads are found at elevations of between 7,380 and 11,800 ft (2,250 and 3,600 m) and the Columbia spotted frog can live at elevations as high as 9,480 ft (2,890 m) in the Greater Yellowstone Ecosystem.Exotic species of fauna such as the zebra and quagga mussels and the New Zealand mud snail are invasive species that can greatly impact fish species. Though the mussel species are not known to be in Wyoming, several surrounding regions have reported them. The New Zealand mud snail has been found in the Shoshone River east of the forest. Forest managers have established a preventative program to try to keep these species from entering forest waterways.
[EX A]:
What is the name of the invasive species that has been found in the Shoshone river?
