Input: Wood
During the development of a tree, the lower limbs often die, but may remain attached for a time, sometimes years. Subsequent layers of growth of the attaching stem are no longer intimately joined with the dead limb, but are grown around it. Hence, dead branches produce knots which are not attached, and likely to drop out after the tree has been sawn into boards.

Are the knots that dead tree limbs form attached or not attached?
Output: not attached

Input: Portugal
With the occupation by Napoleon, Portugal began a slow but inexorable decline that lasted until the 20th century. This decline was hastened by the independence in 1822 of the country's largest colonial possession, Brazil. In 1807, as Napoleon's army closed in on Lisbon, the Prince Regent João VI of Portugal transferred his court to Brazil and established Rio de Janeiro as the capital of the Portuguese Empire. In 1815, Brazil was declared a Kingdom and the Kingdom of Portugal was united with it, forming a pluricontinental State, the United Kingdom of Portugal, Brazil and the Algarves.

Under whose occupation did Portugal begin a slow decline?
Output: Napoleon

Input: United States Air Force
The act created the National Military Establishment (renamed Department of Defense in 1949), which was composed of three subordinate Military Departments, namely the Department of the Army, the Department of the Navy, and the newly created Department of the Air Force. Prior to 1947, the responsibility for military aviation was shared between the Army (for land-based operations), the Navy (for sea-based operations from aircraft carriers and amphibious aircraft), and the Marine Corps (for close air support of infantry operations). The 1940s proved to be important in other ways as well. In 1947, Captain Chuck Yeager broke the sound barrier in his X-1 rocket-powered aircraft, beginning a new era of aeronautics in America.

What was the National Military Establishment renamed in 1949?
Output: Department of Defense

Input: Seven Years%27 War
Frederick saw Saxony and Polish west Prussia as potential fields for expansion but could not expect French support if he started an aggressive war for them. If he joined the French against the British in the hope of annexing Hanover, he might fall victim to an Austro-Russian attack. The hereditary elector of Saxony, Augustus III, was also elective King of Poland as Augustus III, but the two territories were physically separated by Brandenburg and Silesia. Neither state could pose as a great power. Saxony was merely a buffer between Prussia and Austrian Bohemia, whereas Poland, despite its union with the ancient lands of Lithuania, was prey to pro-French and pro-Russian factions. A Prussian scheme for compensating Frederick Augustus with Bohemia in exchange for Saxony obviously presupposed further spoliation of Austria.

What two geographies did Frederick want for Prussia?
Output:
Saxony and Polish west Prussia
