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. 
Question: What was the name of the technique Andrée tried on a couple of Svea flights?

Ex Output:
drag-rope steering technique.

Passage: Anne is in Cannes with her husband Michael, a prominent movie producer. As the festival ends she learns that the vacation she and her husband were supposed to go on in Paris will be slightly delayed as they need to go to Budapest first. They plan to fly to Paris, but the pilot suggests Anne not fly due to an ear infection. Michael's producing partner Jacques offers to drive Anne to Paris himself.
What is supposed to be a short car ride quickly devolves into a pleasant leisurely trip as Jacques, a French foodie, can't resist taking any opportunity he can to stop every hour or so to sample new food. He is also openly flirtatious with Anne but she begins to question his intentions when he repeatedly uses her credit card to foot the bill for the gourmet meals they are sampling. They visit a church where Anne grieves the baby she lost, and tells Jacques she wears her locket necklace in his honor.  They share a romantic dinner together where Jacques admires Anne's photography, and asks why she doesn't share it with her husband.
Later, on the road, Jacques confides that only he knows his brother's death was a suicide, and he carries that burden so his nephew doesn't have to know.  They finally reach the place where Anne is staying and almost kiss, but the elevator doors close in on them.  Anne sees Jacques has driven away, but he returns to kiss her passionately and ask her to a rendez-vous with him later in San Francisco.
Days later, she receives a package from Jacques with chocolate roses and the money she had lent him on the trip.  It includes a note that reminds her of the restaurant they will be meeting at, and she smiles at the camera suggestively. 
Question: In whose honor does Anne wear a locket?

Ex Output:
the baby she lost.

Passage: The mid-19th-century patriarch of the Hungarian-Jewish Sonnenschein family is a tavern owner who makes his own popular distilled herb-based tonic in Austria-Hungary. The tonic, called Taste of Sunshine, is later commercially made by his son, Emmanuel, bringing the family great wealth and prestige. He builds a large estate where his oldest son, Ignatz, falls in love with his first cousin, Valerie, despite the disapproval of Emmanuel and Rose. Ignatz, while studying in law school, begins an affair with Valerie. Ignatz graduates and later earns a place as a respected district judge, when he is asked by the chief judge to change his Jewish surname in order to be promoted to the central court. The entire generation – Ignatz, his physician brother Gustave and photographer cousin Valerie – change their last name to Sors ("fate"), a more Hungarian-sounding name. Ignatz then gets promoted when he tells the Minister of Justice a way to delay the prosecution of corrupt politicians.
In the spring of 1899, when Valerie becomes pregnant, she and Ignatz happily marry before the birth of their son, Istvan. Their second son, Adam, is born in 1902. Ignatz continues to support the Habsburg monarchy, while Gustave pushes for a communist revolution. Both brothers enlist in the Austro-Hungarian Army as officers during World War I. In the days after the war, Valerie briefly leaves him for another man, the old monarchy collapses, and Ignatz loses his judicial position under a series of short-lived socialist and communist regimes in which Gustave is involved. When a new monarchy emerges and asks Ignatz to oversee trials of retribution against the communists, he declines and is forced to retire. His health deteriorates rapidly and he dies, leaving Valerie as head of the family. 
Question: What are the names of Ignatz and Valerie's sons?

Ex Output:

Istvan.
