Given the task definition, example input & output, solve the new input case.
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: 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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

New input case for you: Passage: From the moment the three were grounded on 14 July, Strindberg's highly specialized cartographic camera, which had been brought to map the region from the air, became instead a means of recording daily life in the icescape and the constant danger and drudgery of the trek. Strindberg took about 200 photos with his seven-kilogram (15 lb) camera over the course of the three months they spent on the pack ice, one of the most famous being his picture of Andrée and Frænkel contemplating the fallen Eagle (see image above).Andrée and Frænkel also kept meticulous records of their experiences and geographical positions, Andrée in his "main diary," Frænkel in his meteorological journal. Strindberg's own stenographic diary was more personal in content, and included his general reflections on the expedition, as well as several messages to his fiancée Anna Charlier. All three manuscripts were eventually retrieved from the ice on Kvitøya in 1930.
The Eagle had been stocked with safety equipment such as guns, snowshoes, sleds, skis, a tent, a small boat (in the form of a bundle of bent sticks, to be assembled and covered with balloon silk), most of it stored not in the basket but in the storage space arranged above the balloon ring. These items had not been put together with great care, or with any acknowledgment of adopting indigenous peoples' techniques for dealing with the extreme environment. In this, Andrée contrasted not only with later but also with many earlier explorers.
Sven Lundström points to the agonizing extra efforts that became necessary for the team due to Andrée's mistaken design of the sleds, with a rigid construction that borrowed nothing from the long proven Inuit sleds, and were so impractical for the difficult terrain. Andrée called it "dreadful terrain", with channels separating the ice floes, high ridges, and partially iced-over melt ponds. The men's clothes included no furs but were woolen coats and trousers, plus oilskins. They wore the oilskins but the explorers reported always seeming to be damp or wet from the half-frozen pools of water on the ice and the typically foggy, humid Arctic summer air, and preoccupied with drying their clothes, mainly by wearing them. It would have meant certain death to lose the provisions lashed to one of the inconvenient sleds into one of the many channels that had to be laboriously crossed.
Output:
What is the name of the person whose fiancée was Anna Charlier?
