Question: Question: Which of the empires that succeeded the Achaemenid Empire had the smallest number of people? Passage:Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 7000 BC. The south-western and western part of the Iranian Plateau participated in the traditional Ancient Near East with Elam, from the Early Bronze Age, and later with various other peoples, such as the Kassites, Mannaeans, and Gutians. Georg Wilhelm Friedrich Hegel calls the Persians the "first Historical People". The Medes unified Iran as a nation and empire in 625 BC. The Achaemenid Empire (550–330 BC), founded by Cyrus the Great, was the first true global superpower state and it ruled from the Balkans to North Africa and also Central Asia, spanning three continents, from their seat of power in Persis (Persepolis). It was the largest empire yet seen and the first world empire. The Achaemenid Empire was the only civilization in all of history to connect over 40% of the global population, accounting for approximately 49.4 million of the world's 112.4 million people in around 480 BC. They were succeeded by the Seleucid, Parthian, and Sasanian Empires, who successively governed Iran for almost 1,000 years and made Iran once again as a leading power in the world. Persia's arch-rival was the Roman Empire and its successor, the Byzantine Empire.

Question: Question: Between the town where the field hospital was located and its nearest city, which one was established first? Passage:Chisholm and Knocker soon came to the conclusion that they could save more lives by treating the wounded directly on the front lines. In November, they decided to leave the corps and set up their own dressing station five miles east in a town named Pervyse, north of Ypres, just one hundred yards from the trenches. Here, in a vacant cellar which they named "Poste de Secours Anglais" ("British First Aid Post"), the two would spend the next three and a half years tending to the wounded. No longer affiliated with the Belgian Red Cross, they began acting completely as free agents and had to support their work by raising their own funds. Through sheer perseverance Knocker was able to arrange for the two of them to be officially seconded to the Belgian garrison stationed there. In January 1915, they were both decorated by King Albert I of Belgium with the Order of Léopold II, Knights Cross (with palm) for their courageous work on the front lines. They were also awarded the British Military Medal and both made Officers of the Most Venerable Order of St. John of Jerusalem. Chisholm was also decorated with the Queen Elisabeth Medal of Belgium and the British campaign medals, including the 1914 Star. The two became instant celebrities earning the distinction of being among the most photographed women of the war.

Question: Question: How many soldiers comprised the West Yorkshire Regiment the year that Jimmy Seed joined it? Passage:Seed spent the 1914–15 season playing in Sunderland reserves, he scored plenty of goals as the team lifted the Durham Senior Cup. Official League football was suspended at the end of that season because of the outbreak of World War I. At the end of the season, the 20-year-old Seed joined the Army Cyclist Corps. In the summer of 1916, he was drafted to France with the 8th battalion of the West Yorkshire Regiment. Seed suffered with depression after his arrival and in July 1917, he was gassed when a German aeroplane dropped mustard gas bombs on a house in Nieuwpoort, Belgium, in which he was sleeping. He returned to England to convalesce and returned to France in August 1918, until being evacuated after being gassed in Valenciennes, France two months later. With the cessation of hostilities, Seed played a Victory League match for Sunderland against Durham City in 1918, however his lungs were weak and he had a poor game. On the strength of that performance the Sunderland directors decided that Seed's wartime experience had finished him as a footballer and gave him a free transfer. Seed never played an official first team game for Sunderland. Seed was discharged from the army in March 1919.


Answer:
In the summer of 1916, he was drafted to France with the 8th battalion of the West Yorkshire Regiment
