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.
Q: Passage: The second half of the 19th century has often been called the Heroic Age of Antarctic Exploration. The inhospitable and dangerous Arctic and Antarctic regions appealed powerfully to the imagination of the age, not as lands with their own ecologies and cultures, but as challenges to be conquered by technological ingenuity and manly daring.
Salomon August Andrée shared these enthusiasms, and proposed a plan for letting the wind propel a hydrogen balloon from Svalbard across the Arctic Sea to the Bering Strait, to fetch up in Alaska, Canada, or Russia, and passing near or even right over the North Pole on the way. Andrée was an engineer at the patent office in Stockholm, with a passion for ballooning.
He bought his own balloon, the Svea, in 1893 and made nine journeys with it, starting from Gothenburg or Stockholm and traveling a combined distance of 1,500 kilometres (930 mi). In the prevailing westerly winds, the Svea flights had a strong tendency to carry him uncontrollably out to the Baltic Sea and drag his basket perilously along the surface of the water or slam it into one of the many rocky islets in the Stockholm archipelago.
On one occasion he was blown clear across the Baltic to Finland. His longest trip was due east from Gothenburg, across the breadth of Sweden and out over the Baltic to Gotland. Even though he saw a lighthouse and heard breakers off Öland, he remained convinced that he was traveling over land and seeing lakes.During a couple of Svea flights, Andrée tested and tried out the drag-rope steering technique which he had developed and wanted to use on his projected North Pole expedition. Drag ropes, which hang from the balloon basket and drag part of their length on the ground, are designed to counteract the tendency of lighter-than-air craft to travel at the same speed as the wind, a situation that makes steering by sails impossible. The friction of the ropes was intended to slow the balloon to the point where the sails would have an effect (beyond that of making the balloon rotate on its axis). Andrée reported, and presumably believed, that with drag rope/sails steering he had succeeded in deviating about ten degrees either way from the wind direction.
This notion is rejected by modern balloonists; the Swedish Ballooning Association maintains that Andrée's belief that he had deviated from the wind was mistaken, being misled by inexpertise and a surfeit of enthusiasm in an environment of variable winds and poor visibility. Use of drag ropes—prone to snapping, falling off, or becoming entangled with each other or the ground, in addition to being ineffective—is not considered by any modern expert to be a useful steering technique.
