Question: 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 dam and hydroelectric power plant were constructed as the Gavins Point Project from 1952 to 1957 by the United States Army Corps of Engineers as part of the Pick-Sloan Plan Question: When was the dam that was part of the Missouri River Basin Project completed?

Answer: Answer: 1957


Question: Passage: Following the postwar crime comics vogue spearheaded by publisher Lev Gleason's Crime Does Not Pay, which by 1948 was selling over a million copies a month, came romance comics, which by 1949 outsold all other genres, and horror comics. The same month in which Adventures into the Unknown premiered, the comic-book company EC, which would become the most prominent horror-comics publisher of the 1950s, published its first horror story, "Zombie Terror", by the then relatively unknown writer and artist Johnny Craig, in the superhero comic Moon Girl #5. Almost simultaneously,Trans-World Publications issued its one-and-only comic, the one-shot Mysterious Traveler Comics #1 (November 1948), based on the Mutual Broadcasting Network's radio show of that name and including amid its crime and science-fiction stories a reprint of the Edgar Allan Poe adaptation "The Tell Tale Heart", reprinted from Charlton Comics' Yellowjacket Comics #6. Street and Smith also published two issues of "Ghost Breakers" in late 1948. (ibid GCDB)
