In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

[Q]: 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).
Link Information: The timing of the Great Depression varied across nations; in most countries, it started in 1929 and lasted until the late 1930s. Question: Which 1930s event that stalled the Flanley initiative last the longest?
[A]: Answer: The Great Depression

[Q]: Passage: As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92mm (.312in) MG 15 machine gun for the rear seat was added to the third prototype.
Link Information: he World War II MG 15 was used in nearly all Luftwaffe aircraft with a flexible-mount defensive position. Question: What other planes were fitted with the MG 15?
[A]: Answer: nearly all Luftwaffe aircraft with a flexible-mount defensive position

[Q]: Passage: Before the 2012 Republican primary, Barron helped organize the "Draft Cheney 2012" movement, which was to convince the former vice president Cheney to seek the Republican presidential nomination in 2012. Early in the 2012 Republican primary process, Barron endorsed Herman Cain for the 2012 U.S. presidential election. After Cain dropped out, Barron endorsed Republican and later Libertarian Party presidential candidate Gary Johnson for the 2012 U.S. presidential election. He was a delegate to the 2012 Libertarian National Convention. In the 2012 Republican primary in the District of Columbia, Barron voted for Ron Paul. In October 2012, however, he announced he had decided to support and vote for Mitt Romney for President, even while continuing to serve as a D.C. elector for Johnson.

[A]:
Answer: Romney
