Article: After the Dambusters raid in 1943 an entirely new system was developed that was required to knock down any low-flying aircraft with a single hit. The first attempt to produce such a system used a 50 mm gun, but this proved inaccurate and a new 55 mm gun replaced it. The system used a centralised control system including both search and targeting radar, which calculated the aim point for the guns after considering windage and ballistics, and then sent electrical commands to the guns, which used hydraulics to point themselves at high speeds. Operators simply fed the guns and selected the targets. This system, modern even by today's standards, was in late development when the war ended.

Question: What replaced the 50 millimeter gun that was not accurate?
Ans: a new 55 mm gun

Article: The road to Yorktown and America's independence from Great Britain led through North Carolina. As the British Army moved north from victories in Charleston and Camden, South Carolina, the Southern Division of the Continental Army and local militia prepared to meet them. Following General Daniel Morgan's victory over the British Cavalry Commander Banastre Tarleton at the Battle of Cowpens on January 17, 1781, southern commander Nathanael Greene led British Lord Charles Cornwallis across the heartland of North Carolina, and away from the latter's base of supply in Charleston, South Carolina. This campaign is known as "The Race to the Dan" or "The Race for the River."

Question: What was the date of the battle of Cowpens?
Ans: January 17, 1781

Article: During the late 1920s and early 1930s, Eisenhower's career in the post-war army stalled somewhat, as military priorities diminished; many of his friends resigned for high-paying business jobs. He was assigned to the American Battle Monuments Commission directed by General Pershing, and with the help of his brother Milton Eisenhower, then a journalist at the Agriculture Department, he produced a guide to American battlefields in Europe. He then was assigned to the Army War College and graduated in 1928. After a one-year assignment in France, Eisenhower served as executive officer to General George V. Mosely, Assistant Secretary of War, from 1929 to February 1933. Major Dwight D. Eisenhower graduated from the Army Industrial College (Washington, DC) in 1933 and later served on the faculty (it was later expanded to become the Industrial College of the Armed Services and is now known as the Dwight D. Eisenhower School for National Security and Resource Strategy).

Question: During the 1920s, for what federal department did Milton Eisenhower work?
Ans: Agriculture
