[EX Q]: Question: What country was Hope sent to after Erskine's death? Passage:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.

[EX Q]: Question: In what year did Ostashenko's country join the first world war? Passage:Ostashenko was born on 19 June 1896 in the village of Bolshaya Lyubshchina, Yanovichskoy volost, Vitebsky Uyezd, Vitebsk Governorate to a peasant family. He graduated from four grades at a gymnasium. During World War I, he was mobilized for military service on 7 August 1915, being sent to the 4th Company of the Reserve Battalion of the Petrograd Lifeguard Regiment in Petrograd. With the battalion, he fought with the Southwestern Front between July 1916 and February 1917, then returned to Petrograd before being demobilized on 13 March 1918. In July, he volunteered for the Red Army, serving in the Vitebsky Uyezd military commissariat as a clerk and instructor organizer. From May 1919 Ostashenko served as a Red Army man and political soldier – a Communist mobilized to conduct political work in the army – in the march battalion of the Vitebsk Reserve Regiment. From July he served as an assistant platoon commander in the 84th Rifle Regiment of the 10th Rifle Division, which fought against the Northwestern Army near Petrograd as part of the 15th Army of the Western Front. He entered the Smolensk Commanders' Infantry Courses in November and upon graduation in June 1920 became a platoon commander in the Rzhev-based 2nd Reserve Regiment. This assignment proved to be brief and a month later, Ostashenko became adjutant of the 4th Landing Detachment for armored trains with the Western Front. He fought with the detachment, which provided landing parties for armored trains, in the Polish–Soviet War and was wounded twice.

[EX Q]: Question: Did the team that lost the game in which Duda hit his first career grand slam make the playoffs that year? Passage:On July 29, during a 7–3 loss to the San Diego Padres, Duda became the eleventh Mets player to hit three home runs in a single game, and only the second Met to do so at home after Kirk Nieuwenhuis had accomplished the feat less than a month before. Duda set a Mets franchise record on August 1 when eight of his consecutive hits came in the form of home runs; he and teammate Noah Syndergaard were named National League Co-Players of the Week for the week ending on August 2. On September 26, Duda hit his first career grand slam in the Mets' 10–2 victory over the Cincinnati Reds. That victory clinched the NL East division title for the New York Mets. On the final day of the season, Duda was hit by a pitch from the Washington Nationals' Tanner Roark, giving him 14 total HBP on the season and breaking the Mets single season record, previously shared by John Olerud and Ron Hunt. For the season, he had the highest fly ball percentage (50.6%), and the lowest ground ball percentage (27.4%), of all major league hitters.
