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 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?

Answer: Answer: The Great Depression


Question: Passage: McSweeney is a conservative Republican. He supports finishing the War on Terror and the Iraq War. McSweeney also promises to make President Bush's tax cuts permanent, to offer tax cuts to companies that invest in new jobs and workers. He is opposed to raising the federal minimum wage, currently $5.15 an hour. McSweeney vows to try and freeze the total amount of federal spending, excluding national security, homeland security, and social security. McSweeney is pro-life and opposes abortion except in cases of rape, incest, and when the life of the mother is at stake. McSweeney also opposes embryonic stem cell research, instead favoring research on umbilical cord blood. He supports 2nd Amendment rights and opposes a ban on semi-automatic firearms. McSweeney supports carrying concealed weapon. McSweeney opposes same-sex marriage as well as civil unions for gay couples and is in favor of amending the Constitution to ban sex same marriages. McSweeney argued that a wall should be built along part of the 2,000-plus-mile U.S.-Mexican border, focusing on the urban areas. McSweeney favored means-testing as a way to reduce the cost of Medicare Part D, which is the prescription drug benefit. McSweeney said, "I believe we need to means-test the Part D prescription drug program that was just adopted by Congress." 
 Link Information: members of the Republican Party actively oppose the federal funding of embryonic stem cell research beyond the original lines because it involves the destruction of human embryos. Question: Why would someone like McSweeny oppose embryonic stem cell research?

Answer: Answer: because it involves the destruction of human embryos.


Question: Passage: Chamberlain then went to Geneva, where he studied under Carl Vogt (a supporter of racial typology at the University of Geneva), Graebe, Müller Argoviensis, Thury, Plantamour, and other professors. He studied systematic botany, geology, astronomy, and later the anatomy and physiology of the human body. Under the tutelage of Professor Julius von Wiesner of the University of Vienna, Chamberlain studied botany in Geneva, earning a Bacheliers en sciences (BSc) physiques et naturelles in 1881. His thesis, Recherches sur la sève ascendante (Studies on rising sap), was not finished until 1897 and did not culminate in a further qualification. The main thrust of Chamberlain's dissertation is that the vertical transport of fluids in vascular plants via xylem cannot be explained by the fluid mechanical theories of the time, but only by the existence of a "vital force" (force vitale) that is beyond the pale of physical measurement. He summarises his thesis in the Introduction: Physical arguments, in particular transpirational pull and root pressure, have since been shown to be adequate for explaining the ascent of sap.
 Link Information: Botany, also called plant science(s), plant biology or phytology, is the science of plant life Question: Of the subjects Chamberlain studied, which is the study of plants?

Answer:
Answer: Botany
