In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage.

Example Input: Question: What is the population of the city where the port the Sibiryakov reached after 65 days is located? Passage:A. Sibiryakov sailed on 28 June 1932 from the Krasny (previously Sobornoy) docks in Arkhangelsk, crossed the Kara Sea and chose a northern, unexplored way around Severnaya Zemlya to the Laptev Sea. In September, after calling at Tiksi and the mouth of the Kolyma, the propeller shaft broke and the icebreaker drifted for 11 days. However, A. Sibiryakov crossed the Chukchi Sea using improvised sails and arrived in the Bering Strait in October. A. Sibiryakov reached the Japanese port of Yokohama after 65 days, having covered more than in the Arctic seas. This was regarded as a heroic feat of Soviet polar seamen and Chief of Expedition Otto Schmidt and Captain Vladimir Voronin were received with many honors at their return to Russia.

Example Output: b

Example Input: Question: Which 1930s event that stalled the Flanley initiative last the longest? Passage:By the 1920s, SCGX was doubling annually and had emerged as the "fastest growing grain market in the world"; transacting 22 million bushels in 1928 (valued at $336 million in 2018), resulting from its location in the heart of the Corn Belt and self-imposed standards before the Grain Standards Act of 1916 including species admittance and non-mixing. However, its growth was limited by shipping rates. With the trucking industry and Interstate Highway System not yet developed, SCGX was constrained by monopolized railroad rates, primarily by the Great Northern Railway. Exhausting their bargaining power with the Interstate Commerce Commission, SCGX President Charles C. Flanley directed future lobbying efforts to unlocking barge navigation of the Missouri River. His initiative was stalled throughout the 1930s by the Great Depression and Dust Bowl. In 1938, a renewed thirteen year campaign led by Secretary William Henry Marriott finally opened commercial navigation of the Missouri River and helped establish the Missouri River Basin Project, which included development of the Gavins Point Dam. The alternate transportation succeeded in breaking the railroad's monopoly. By the 1970s, SCGX was among the largest exchanges in the world; transacting over 100 million bushels annually (valued at $1 billion as of 2018).

Example Input: Question: Of the newspapers that gave Mad Dogs & Englishmen a poor review, which was established last? Passage:Roger Ebert of the Chicago Sun-Times gave the film three stars out of four and wrote that "the musical scenes are the best rock coverage since 'Woodstock.' The sound is first rate, for one thing, and director Pierre Adidge has some idea of why Cocker electrifies a crowd." Vincent Canby of The New York Times called the film a "most satisfying, record-album of a movie" which "patronizes neither its audience nor its stars ... It is uncluttered, one of the best concert films so far." A review in Variety said, "Considerable technical expertise has gone into this production, and though the objective may be clear, it just hasn't turned out to be another 'Woodstock,' possibly because Joe Cocker's personality isn't all that endearing." Gene Siskel of the Chicago Tribune rated the film three stars out of four and wrote, "'Mad Dogs' is distinguishable from other 'rockumentaries' because it deals almost exclusively with the musician and his music. There are few side trips to cultural comments." Robert Hilburn of the Los Angeles Times stated, "As a film, 'Mad Dogs and Englishmen' is a good concert. For much of the picture's 114 minutes, the camera is on Joe Cocker, by most standards the best and most exciting singer in rock music ... But 'Mad Dogs and Englishmen,' unfortunately, fails in the end to rise above this interesting, but clearly limited historical summary of the Cocker tour. As a film, it doesn't establish its own importance." A negative review by Tom Zito of The Washington Post advised readers to "Forget the film and try the record," explaining, "What emerges from all this is roughly two hours of footage that looks terrible on the screen and sounds almost as bad. The film is projected in an annoying square format, except for the moments when the screen area is broken up into some poorly coordinated split-screen effects. The camerawork is often sloppy ... the whole thing winds up looking and sounding like a cheap, imitation (indoor) 'Woodstock.'" James D. White of The Monthly Film Bulletin declared that "The music itself is excellent," but "The film's information content is minimal; and one's heart sinks as the screen is split into a double image for the first number and as the mandatory shots—of excited fans, of joint-rolling in a hotel bedroom, of an interview with a vacuous groupie—are inevitably wheeled out."
