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.

Passage: Bach is believed to have written Christ lag in Todes Banden in 1707. He was a professional organist aged 22, employed from 1703 in Arnstadt as the organist of the New Church (which replaced the burned Bonifatiuskirche, today known as the Bach Church). At age 18, he had inspected the new organ built by Johann Friedrich Wender, was invited to play one Sunday, and was hired. The organ was built on the third tier of a theatre-like church. Bach's duties as a church musician involved some responsibility for choral music, but the exact year he began composing cantatas is unknown. Christ lag in Todes Banden is one of a small group of cantatas that survive from his early years. According to the musicologist Martin Geck, many details of the score reflect "organistic practice".In Arnstadt, the Kantor (church musician) Heindorff was responsible for church music in the Upper Church (Liebfrauenkirche), and the New Church where Bach was the organist. He typically conducted music in the Upper Church and would appoint a choir prefect for vocal music in the New Church. Wolff notes that "subjecting his works to the questionable leadership of a prefect" was not what Bach would have done. Therefore, most cantatas of the period are not for Sunday occasions, but restricted to special occasions such as weddings and funerals. Christ lag in Todes Banden is the only exception, but was most likely composed not for Arnstadt but for an application to a more important post at the Divi Blasii church in Mühlhausen.

What was the name of the Bach Church when Bach was the organist?

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.

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

Passage: The Norwegian Bratvaag expedition, studying the glaciers and seas of the Svalbard archipelago from the Norwegian sealing vessel Bratvaag of Ålesund, found the remains of the Andrée expedition on 5 August 1930. Kvitøya was usually inaccessible to the sealing or whaling ships of the time, as it is typically surrounded by a wide belt of thick polar ice and often hidden by thick ice fogs. However, summer in 1930 had been particularly warm, and the surrounding sea was practically free of ice. As Kvitøya was known to be a prime hunting ground for walrus and the fogs over the island on that day were comparatively thin, some of the crew of the Bratvaag took this rare opportunity to land on what they called the "inaccessible island".Two of the sealers in search of water, Olav Salen and Karl Tusvick, discovered Andrée's boat near a small stream, frozen under a mound of snow and full of equipment, including a boathook engraved with the words "Andrée's Polar Expedition, 1896". Presented with this hook, the Bratvaag's captain, Peder Eliassen, assigned the crew to search the site together with the expedition members. Among other finds, they uncovered a journal and two skeletons, identified as Andrée's and Strindberg's remains by monograms found on their clothing.The Bratvaag left the island to continue its scheduled hunting and observations, with the intent of coming back later to see if the ice had melted further and uncovered more artifacts. Further discoveries were made by the M/K Isbjørn of Tromsø, a sealing sloop chartered by news reporters to waylay the Bratvaag. Unsuccessful in this, the reporters and the Isbjørn crew made instead for Kvitøya, landing on the island on 5 September in fine weather and finding even less ice than the Bratvaag had. After photographing the area, they searched for and found Frænkel's body, and additional artifacts, including a tin box containing Strindberg's photographic film, his logbook, and maps. The crews of both ships turned over their finds to a scientific commission of the Swedish and Norwegian governments in Tromsø on 2 and 16 September, respectively. The bodies of the three explorers were transported to Stockholm, arriving on 5 October.
