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: Two aliens, Nukie and Miko, spend their time flying through space in the form of stars and looking for fun. The two come across the planet Earth and, while trying to survey the planet, get caught in its gravitational pull and end up crash landing. During the crash, the two are separated, with Nukie ending up in the African savanna and Miko falling into the hands of a Space Federation in the United States. Upon discovering Miko's crash site, the agency take the alien in to perform tests on him, while Miko cries out for Nukie. Miko reaches out to Nukie telepathically and informs him that he is being held captive in America. The head of the operation, Dr. Glynn sends Dr. Eric Harvey to Nairobi to investigate the other crash site. During their experiments, the scientists discover that Miko is a being made of pure energy.
Nukie, meanwhile, begins to explore his surroundings, attempting to communicate telepathically with the animals he encounters to ascertain the location of America. The animals don't understand and – much to Nukie's frustration – run away. He then comes across two children, Tiko and Toki, who seem to be able to understand Nukie. He asks them for their help with finding America, but they run off vowing not to tell anybody about what has happened.
In America, Miko is subjected to more painful testing to explore his physical makeup. Miko's brain patterns show images of the animals which Nukie sees, indicating that Nukie is transmitting his brainwaves to Miko. Nukie decides to rest in the shade of a tree, turning invisible as he does so. Tiko and Toki pass by and Nukie is awoken by a flock of birds, becoming visible once more. He surmises that his light beam transformer must be working once more, and he succeeds in flying. Landing near a stream, he tastes the water and notices his reflection, which he claims is different from usual.
Example Output: Who is the alien friend of the creature that crashes in the African savanna?

Example Input: Passage: The first recorded inhabitants of the Susquehanna River valley were the Susquehannocks, an Iroquoian speaking people. Their name meant "people of the muddy river" in the Algonquian, but their name for themselves is unknown. Decimated by diseases and warfare, they had largely died out, moved away, or been assimilated into other tribes by the early 18th century. The lands of the West Branch Susquehanna River valley were then chiefly occupied by the Munsee phratry of the Lenape (or Delaware), and were under the nominal control of the Five (later Six) Nations of the Iroquois. Two important paths of these native indigenous peoples ran along parts of White Deer Hole Creek.The Great Island Path was a major trail that ran north along the Susquehanna River from the Saponi village of Shamokin at modern Sunbury, fording the river there and following the west bank of the West Branch Susquehanna River north until White Deer Hole valley. The path turned west at Allenwood and followed White Deer Hole Creek until about the present location of Elimsport. There it headed northwest, crossed North White Deer Ridge and passed west through the Nippenose valley, then turned north and crossed Bald Eagle Mountain via McElhattan Creek and ran along the south bank of the river to the Great Island (near the present day city of Lock Haven). The stretch from the mouth of the creek to the Nippenose valley is approximately followed by Route 44. From the Great Island, the Great Shamokin Path continued further west to the modern boroughs of Clearfield and Kittanning, the last on the Allegheny River.
Culbertson's Path followed White Deer Hole Creek west from Allenwood, then followed Spring Creek north, crossed Bald Eagle Mountain and followed Mosquito Run to the river at the current borough of Duboistown. Here it crossed the river to "French Margaret's Town" (western modern day Williamsport) before joining the major Sheshequin Path, which led north up Lycoming Creek to the North Branch of the Susquehanna River, modern New York, and the Iroquois there. These trails were only wide enough for one person, but settlers in White Deer Hole valley broadened the path to DuBoistown to take grain to Culbertson's mill on Mosquito Run, hence the name. Culbertson's Path was used as a part of the Underground Railroad until the American Civil War began in 1861. Escaped slaves would often wade in creeks to hide their scent from pursuing bloodhounds. In 2009, there is still a "Culbertson's Trail", for hiking over Bald Eagle Mountain from Pennsylvania Route 554 to Duboistown.
Example Output: What is the name of the location that the people who widened the trails settled in?

Example Input: Passage: Amy Winslow is an art student majoring in painting, who is all by her own. Her mother died when she was a child and her father is not around. As a student she has financial problems, so she is surprised when the couple Joan and Stuart Quinn (Connie Sellecca and David Dukes) decide to take her in their house for a small amount of rent. Little does Amy know that Joan is following her every step through secret cameras, and that she has a hidden agenda for her. Initially, Amy is very content living with the Quinns, believing that she has found the family she has never had. When she loses the university's financial aide through an administration error, Joan immediately steps in to take care of her. They both drink a large amount of wine, and then Joan announces that because she is infertile, they are looking for a surrogate mother. She then tells Amy that they feel that she is the perfect candidate. Amy is flattered, and next day discusses the situation with her friendly teacher Eric Shaw. She then agrees when the Quinns propose to pay for her college fees if she helps them out.
When Amy is a few months pregnant, Joan starts to show strange behavior. Amy feels smothered by Joan's overbearing attitude, feeling that she is being treated like a ten-year-old child. Her oil painting being taken away, Amy looks for it in the basement, only to find old baby clothes. Joan catches her, and becomes furious, scaring Amy away. She later tries to explain the situation by saying that she was pregnant four years ago, though had a miscarriage. Amy does not believe her story, though Eric - who was already 'warned' by Joan that Amy might act paranoid - tells her to focus on her painting, not on the Quinns.
Example Output:
Why does Amy agree to be a surrogate mother?
