PROBLEM: Passage: Coming off of their surprising home win over the Bears, the Lions flew to FedExField for a Week 5 intraconference duel with the Washington Redskins.  Heading into the game, Detroit had never won a game against the Redskins in Washington, D.C. (0-20) After a scoreless first quarter, the Lions trailed as in the second quarter when Redskins QB Jason Campbell completed a 7-yard TD pass to TE Chris Cooley, followed by FB Mike Sellers getting a 1-yard TD run.  In the third quarter, Detroit managed to get on the board with kicker Jason Hanson getting a 39-yard field goal.  However, Washington came right back with DE Andre Carter sacking Lions QB Jon Kitna in the endzone for a safety.  In the fourth quarter, the Redskins sealed Detroit's fate with Campbell completing an 8-yard TD pass to Sellers, kicker Shaun Suisham nailing a 28-yard field goal, and CB Carlos Rogers returning an interception 61 yards for a touchdown. With the loss, not only did the Lions fall to 3-2 heading into their bye week, but lessened their record to 0-21 against the Redskins in Washington, D.C.

PROBLEM: Passage: The Fourth Ottoman-Venetian War, also known as the War of Cyprus  was fought between 1570 and 1573. It was waged between the Ottoman Empire and the Republic of Venice, the latter joined by the Holy League, a coalition of Christian states formed under the auspices of the Pope, which included Spain , the Republic of Genoa, the Duchy of Savoy, the Knights Hospitaller, the Grand Duchy of Tuscany, and other Italian states. The war, the pre-eminent episode of Sultan Selim II's reign, began with the Ottoman invasion of the Venetian-held island of Cyprus. The capital Nicosia and several other towns fell quickly to the considerably superior Ottoman army, leaving only Famagusta in Venetian hands. Christian reinforcements were delayed, and Famagusta eventually fell in August 1571 after a siege of 11 months. Two months later, at the Battle of Lepanto, the united Christian fleet destroyed the Ottoman fleet, but was unable to take advantage of this victory. The Ottomans quickly rebuilt their naval forces, and Venice was forced to negotiate a separate peace, ceding Cyprus to the Ottomans and paying a tribute of 300,000 ducats.
Question: When did the siege of Famagusta begin?

SOLUTION: date

PROBLEM: Passage: In 1939, the United States had renounced its trade treaty with Japan; and, beginning with an aviation gasoline ban in July 1940, Japan became subject to increasing economic pressure. During this time, Japan launched its first attack against Changsha, a strategically important Chinese city, but was repulsed by late September. Despite several offensives by both sides, the war between China and Japan was stalemated by 1940. To increase pressure on China by blocking supply routes, and to better position Japanese forces in the event of a war with the Western powers, Japan invaded and occupied northern Indochina. Afterwards, the United States embargoed iron, steel and mechanical parts against Japan. Other sanctions soon followed. Chinese nationalist forces launched a large-scale counter-offensive in early 1940. In August, Chinese communists launched an offensive in Central China; in retaliation, Japan instituted harsh measures in occupied areas to reduce human and material resources for the communists. Continued antipathy between Chinese communist and nationalist forces culminated in armed clashes in January 1941, effectively ending their co-operation. In March, the Japanese 11th army attacked the headquarters of the Chinese 19th army but was repulsed during Battle of Shanggao. In September, Japan attempted to take the city of Changsha again and clashed with Chinese nationalist forces.
Question: When did Japan attempt to take the city of Changsha?
