Q: Question: Did Moscow have a greater population than Brussels the year Dodon took office? Passage 1: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 2: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 3:His first two international visits were to Moscow, and Brussels. Since he took office in December 2016 he has made 47 foreign visits to 19 different countries, with 20 of those visits being to Russia. In late October 2019, he visited Istanbul to attend the opening ceremony of Istanbul Airport as well as the ceremony for the Turkish Republic's 95th anniversary. In February and September 2019 respectively, he attended the Munich Security Conference in Germany and the Seventy-fourth session of the United Nations General Assembly in New York City both for the first time. During the UN visit, he referred to his attendance as "a successful one" during which he and his delegation "were able to promote the interests and aspirations of the Republic of Moldova on the international arena". He attended the 2018 FIFA World Cup opening ceremony in Moscow in June 2018 and the 2019 European Games in Minsk just over a year later. In October 2018, He attended a summit of the Organisation internationale de la Francophonie in Yerevan where he delivered a speech in the French language.
