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?

Ex Output:
Answer: The Great Depression

Passage: Baldwin built many 4-4-0 "American" type locomotives (the locomotive that built America). Surviving examples of which include the 1872 Countess of Dufferin and 1875's Virginia and Truckee Railroad No.22 "Inyo", but it was perhaps best known for the 2-8-2 "Mikado" and 2-8-0 "Consolidation" types. It was also well known for the unique cab-forward 4-8-8-2 articulateds built for the Southern Pacific Company and massive 2-10-2 for the Atchison, Topeka and Santa Fe Railway. Baldwin also produced their most powerful steam engines in history, the 2-8-8-4 "Yellowstone" for the Duluth, Missabe and Iron Range Railway. The Yellowstone could put down over of Tractive force. They routinely hauled 180 car trains weighing over . The Yellowstones were so good that the DM&IR refused to part with them; they hauled ore trains well into the diesel era, and the last one retired in 1963. Three have been preserved. One of Baldwin's last new and improved locomotive designs were the 4-8-4 "Northern" locomotives. Baldwin's last domestic steam locomotives were 2-6-6-2s built for the Chesapeake and Ohio Railway in 1949. Baldwin 60000, the company's 1926 demonstration steam locomotive, is on display at the Franklin Institute in Philadelphia. On a separate note, the restored and running 2-6-2 steam locomotive at Fort Edmonton Park was built by Baldwin in 1919.
 Link Information: The Southern Pacific Transportation Company was acquired by the Union Pacific Corporation and merged with their Union Pacific Railroad Question: What is the name of the successor company for the company that received 4-8-8-2 articulateds?

Ex Output:
Answer: Union Pacific Corporation
