Input: Read this: Upon the invitation of Duke Konrad I of Masovia, the Teutonic Knights took possession of Prussia in the 13th century and created a monastic state to administer the conquered Old Prussians. Local Old-Prussian (north) and Polish (south) toponyms were gradually Germanised. The Knights' expansionist policies, including occupation of Polish Pomerania with Gdańsk/Danzig and western Lithuania, brought them into conflict with the Kingdom of Poland and embroiled them in several wars, culminating in the Polish-Lithuanian-Teutonic War, whereby the united armies of Poland and Lithuania, defeated the Teutonic Order at the Battle of Grunwald (Tannenberg) in 1410. Its defeat was formalised in the Second Treaty of Thorn in 1466 ending the Thirteen Years' War, and leaving the former Polish region Pomerania/Pomerelia under Polish control. Together with Warmia it formed the province of Royal Prussia. Eastern Prussia remained under the Knights, but as a fief of Poland. 1466 and 1525 arrangements by kings of Poland were not verified by the Holy Roman Empire as well as the previous gains of the Teutonic Knights were not verified.

Input: Read this: Ducks are medium-sized aquatic birds with broad bills, eyes on the side of the head, fairly long necks, short legs set far back on the body, and webbed feet. Males, known as drakes, are often larger than females (simply known as ducks) and are differently coloured in some breeds. Domestic ducks are omnivores, eating a variety of animal and plant materials such as aquatic insects, molluscs, worms, small amphibians, waterweeds, and grasses. They feed in shallow water by dabbling, with their heads underwater and their tails upended. Most domestic ducks are too heavy to fly, and they are social birds, preferring to live and move around together in groups. They keep their plumage waterproof by preening, a process that spreads the secretions of the preen gland over their feathers.
Question: Do all ducks fly south for the winter?

Output: Most domestic ducks are too heavy to fly


Input: Read this: However, the lifecycles of most living polychaetes, which are almost all marine animals, are unknown, and only about 25% of the 300+ species whose lifecycles are known follow this pattern. About 14% use a similar external fertilization but produce yolk-rich eggs, which reduce the time the larva needs to spend among the plankton, or eggs from which miniature adults emerge rather than larvae. The rest care for the fertilized eggs until they hatch – some by producing jelly-covered masses of eggs which they tend, some by attaching the eggs to their bodies and a few species by keeping the eggs within their bodies until they hatch. These species use a variety of methods for sperm transfer; for example, in some the females collect sperm released into the water, while in others the males have a penis that inject sperm into the female. There is no guarantee that this is a representative sample of polychaetes' reproductive patterns, and it simply reflects scientists' current knowledge.
Question: How many species of polychaetes have impossible lifecycles?

Output: unanswerable


Input: Read this: The Defence Committee—Third Report "Defence Equipment 2009" cites an article from the Financial Times website stating that the Chief of Defence Materiel, General Sir Kevin O’Donoghue, had instructed staff within Defence Equipment and Support (DE&S) through an internal memorandum to reprioritize the approvals process to focus on supporting current operations over the next three years; deterrence related programmes; those that reflect defence obligations both contractual or international; and those where production contracts are already signed. The report also cites concerns over potential cuts in the defence science and technology research budget; implications of inappropriate estimation of Defence Inflation within budgetary processes; underfunding in the Equipment Programme; and a general concern over striking the appropriate balance over a short-term focus (Current Operations) and long-term consequences of failure to invest in the delivery of future UK defence capabilities on future combatants and campaigns. The then Secretary of State for Defence, Bob Ainsworth MP, reinforced this reprioritisation of focus on current operations and had not ruled out "major shifts" in defence spending. In the same article the First Sea Lord and Chief of the Naval Staff, Admiral Sir Mark Stanhope, Royal Navy, acknowledged that there was not enough money within the defence budget and it is preparing itself for tough decisions and the potential for cutbacks. According to figures published by the London Evening Standard the defence budget for 2009 is "more than 10% overspent" (figures cannot be verified) and the paper states that this had caused Gordon Brown to say that the defence spending must be cut. The MoD has been investing in IT to cut costs and improve services for its personnel.
Question: What did former Secretary of State for Defence Mark Stanhope not rule out for spending on personnel?
