Teacher: Now, understand the problem? Solve this instance: Question: How long did the battle in which  the Habsburg Austrian army of Paul Kray triumphed over the Republican French army last? Passage 1: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).
 Passage 2:The 1799 campaign in Italy began with the Battle of Verona, a series of costly but indecisive clashes around Verona on 26 March. At the Battle of Magnano on 5 April, the Habsburg Austrian army of Paul Kray triumphed over the Republican French army of Barthélemy Louis Joseph Schérer. While suffering losses of 4,000 killed and wounded and 2,000 captured, Kray's Austrians inflicted casualties of 3,500 killed and wounded and captured 4,500 men, 18 artillery pieces and seven colors from the French. Two days later, a distraught Schérer begged to be relieved of command. Michael von Melas arrived to take command of the Austrian army from Kray on 9 April. Hearing that 12,000 Austrians were approaching from the Tyrol to the north, Schérer abandoned the line of the Mincio River on 12 April. Leaving 12,000 troops in the fortress of Mantua and 1,600 more in Peschiera del Garda, the demoralized French commander ordered his crippled army to withdraw. As the soldiers fell back, the skies opened up and turned the retreat into a sodden nightmare.
 Passage 3:The beer brand Budweiser has long been a Super Bowl fixture. Its parent company Anheuser-Busch held a long-term contract with the NFL that allowed it to buy several slots of air time from the game's broadcaster each year at a steep discount, a contract that ran through Super Bowl 50; the company continues to buy multiple commercials in each game. Budweiser runs several advertising campaigns throughout each game, one of which has traditionally featured its mascots, the Budweiser Clydesdales. The Clydesdales were included in at least one Super Bowl commercial every year from Super Bowl IX in 1975 through Super Bowl LI in 2017. Budweiser's parent company Anheuser-Busch has been the most successful advertiser in the annual Super Bowl Ad Meter survey organized by USA Today, having finished first on the survey fourteen times. When USA Today held an "All-Time Ad Meter" bracket tournament in 2014, two Budweiser commercials met in the finals; the winner was a 2008 ad spoofing Rocky, which went against its 1999 ad "Separated at Birth", which featured a pair of Dalmatian puppies given to two separate owners, but eventually seeing each other again after one became a mascot dog on the Clydesdales' carriage.
