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.

Question: 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.

Answer: Who is the alien friend of the creature that crashes in the African savanna?


Question: Passage: After Quiriguá's pivotal victory over Copán in 738, K'ak' Tiliw Chan Yopaat rebuilt the main group in the image of Copán itself. Thus, the acropolis, palace, and ballcourt all lie at the southern end of the Great Plaza. The ceremonial centre is laid out around three plazas, the northernmost is the Great Plaza. This plaza measures 325 m (1,066 ft) from north to south and is the largest plaza in the whole Maya region. At the southern end of the Great Plaza is the Ballcourt Plaza, surrounded on three sides by structures associated with the acropolis. The Acropolis Plaza is a fully enclosed plaza within the acropolis itself. The area to the west of the Ballcourt Plaza was probably the riverside docking area and there is evidence that the southern part of the Great Plaza was a marketplace. A number of ceramic-lined wells have been excavated close to the site core, these were all built in the 8th century and although some continued in use into the 9th century, none are known to have been built that late.
1A-1 is an enormous platform forming the northern part of the Great Plaza. It measures 100 by 85 metres (328 by 279 ft) and rises 0.5 metres (20 in) above the level of the southern part of the plaza. It forms the northern portion of the Great Plaza, being built by K'ak' Tiliw Chan Yopaat when he extended the plaza northward. The platform was built from river cobbles and was paved with stone slabs. Platform 1A-1 supported the stelae A, C, D, E and F and Zoomorph B. The platform was built in two phases over about 20 years.
1A-3 is a large mound marking the northern edge of the Great Plaza. It originally measured 82.5 by 20 metres (271 by 66 ft) and was 7 metres (23 ft) high. A 63-metre (207 ft) wide stairway climbed the southern face of the structure from the plaza. The structure was later extended to the north but this second phase of construction was never finished.
The acropolis is the largest architectural complex at Quiriguá, it lies at the southern limit of the ceremonial centre of the city. It is a complex construction, with new buildings and features being added over time. Construction of the acropolis began in 550 and continued through to 810 when the site was abandoned. The acropolis was a palace complex used primarily as an elite residence and for administrative purposes. The acropolis complex includes structures 1B-1, 1B-2, 1B-3, 1B-4, 1B-5 and 1B-6. Excavations of the acropolis encountered the fallen remains of corbel arches, but none are still standing.

Answer: What plaza is at the Ballcourt Plaza at the southern end of?


Question: Passage: Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began working with producers Glen Ballard, Dr. Luke, and Max Martin. After adopting the stage name Katy Perry and being dropped by The Island Def Jam Music Group and Columbia Records, she signed a recording contract with Capitol Records in April 2007.
Perry rose to fame in 2008 with the release of her second album, a pop rock record titled One of the Boys, and its singles "I Kissed a Girl" and "Hot n Cold". The former track also sparked controversy for its sapphic themes. Her third album, Teenage Dream (2010), ventured into disco, and was her first album to top the U.S. Billboard 200. It topped the U.S. Billboard Hot 100 with the singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)", while "The One That Got Away" reached number three on the chart. The album became the first by a female artist to produce five number-one songs in the U.S., and the second overall after Michael Jackson's album Bad. In March 2012, she re-issued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake". Her fourth album, Prism (2013), was her second to peak atop the U.S. charts. It is influenced by pop and dance, and she became the first artist with multiple videos to reach one billion views on Vevo with the videos for its songs "Roar" and "Dark Horse". Her fifth album, Witness (2017), delved into electropop and became her third album to reach number one in the U.S. "Chained to the Rhythm" was the album's most successful single, breaking Spotify's record at the time for most first-day streams for a song by a female artist.
Perry has received various awards, including four Guinness World Records, five American Music Awards, a Brit Award, and a Juno Award, and has been included in the annual Forbes lists of highest-earning women in music from 2011–2018. Her estimated net worth as of 2016 is $125 million. She is one of the best-selling music artists of all time, having sold more than 100 million records globally throughout her career. In film, she released an autobiographical documentary titled Katy Perry: Part of Me in 2012, and voiced Smurfette in the 2011 film The Smurfs and its sequel in 2013. Perry also began serving as a judge on American Idol in 2018.
