Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Now, solve this instance: Passage: The Norwegian Bratvaag expedition, studying the glaciers and seas of the Svalbard archipelago from the Norwegian sealing vessel Bratvaag of Alesund, found the remains of the Andree expedition on 5 August 1930. Kvitya 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 Kvitya 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 Andree's boat near a small stream, frozen under a mound of snow and full of equipment, including a boathook engraved with the words "Andree'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 Andree'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 Isbjrn of Troms, a sealing sloop chartered by news reporters to waylay the Bratvaag. Unsuccessful in this, the reporters and the Isbjrn crew made instead for Kvitya, 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 Frnkel'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 Troms on 2 and 16 September, respectively. The bodies of the three explorers were transported to Stockholm, arriving on 5 October.
