Input: Read this: From the German point of view, March 1941 saw an improvement. The Luftwaffe flew 4,000 sorties that month, including 12 major and three heavy attacks. The electronic war intensified but the Luftwaffe flew major inland missions only on moonlit nights. Ports were easier to find and made better targets. To confuse the British, radio silence was observed until the bombs fell. X- and Y-Gerät beams were placed over false targets and switched only at the last minute. Rapid frequency changes were introduced for X-Gerät, whose wider band of frequencies and greater tactical flexibility ensured it remained effective at a time when British selective jamming was degrading the effectiveness of Y-Gerät.
Question: Why were ports better targets?

Output: Ports were easier to find


Input: Read this: From 1946 to 1964 five Departments of State did the work of the modern Ministry of Defence: the Admiralty, the War Office, the Air Ministry, the Ministry of Aviation, and an earlier form of the Ministry of Defence. These departments merged in 1964; the defence functions of the Ministry of Aviation Supply merged into the Ministry of Defence in 1971.
Question: All former Departments of State (except the Ministry of Aviation Supply) merged in what year?

Input: Read this: During the American Civil War, American cotton exports slumped due to a Union blockade on Southern ports, and also because of a strategic decision by the Confederate government to cut exports, hoping to force Britain to recognize the Confederacy or enter the war. This prompted the main purchasers of cotton, Britain and France, to turn to Egyptian cotton. British and French traders invested heavily in cotton plantations. The Egyptian government of Viceroy Isma'il took out substantial loans from European bankers and stock exchanges. After the American Civil War ended in 1865, British and French traders abandoned Egyptian cotton and returned to cheap American exports,[citation needed] sending Egypt into a deficit spiral that led to the country declaring bankruptcy in 1876, a key factor behind Egypt's occupation by the British Empire in 1882.
Question: To what country's cotton did Southern buyers turn due to the American Civil War?

Output: unanswerable


Input: Read this: The question to be answered is whether a listed species will be harmed by the action and, if so, how the harm can be minimized. If harm cannot be avoided, the project agency can seek an exemption from the Endangered Species Committee, an ad hoc panel composed of members from the executive branch and at least one appointee from the state where the project is to occur. Five of the seven committee members must vote for the exemption to allow taking (to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or significant habitat modification, or to attempt to engage in any such conduct) of listed species.
Question: How many votes must be in favor of the exemption in order to award the exemption?

Output:
Five
