Example Input: 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?
Example Output: Answer: The Great Depression

She earned a degree in chemistry from University College London in 1942 before completing a PhD in the biochemistry of skin burns with Rudolph Peters at the University of Oxford. She visited Harvard Medical School in 1946 to perform research and returned to the UK in 1948. In the same year she married Ernst Boris Chain, a biochemist who had won the Nobel Prize in Physiology or Medicine in 1945, and moved with him to Rome.

Example Input: Passage: Stephen was probably from the town of Ustiug. According to a church tradition, his mother was a Komi woman and his father was a Russian man. Stephen took his monastic vows in Rostov, where he learned Greek and learned his trade as a copyist. In 1376, he voyaged to lands along the Vychegda and Vym rivers, and it was then that he engaged in the conversion of the Zyriane (Komi peoples). Rather than imposing the Latin or Church Slavonic on the indigenous pagan populace, as all the contemporary missionaries did, Stephen learnt their language and traditions and worked out a distinct writing system for their use, creating the second oldest writing system for a Uralic language. Although his destruction of pagan idols (e.g., holy birches) earned him the wrath of some Permians, Pimen, the Metropolitan of All Rus', created him as the first bishop of Perm'. 
 Link Information: none Question: Of the languages Stephen did not impose on the Zyriane, which has the earliest recorded instance?
Example Output:
Answer: none
