Input: Read this: In 1582 the United Provinces invited Francis, Duke of Anjou to lead them; but after a failed attempt to take Antwerp in 1583, the duke left the Netherlands again. After the assassination of William of Orange (10 July 1584), both Henry III of France and Elizabeth I of England declined the offer of sovereignty. However, the latter agreed to turn the United Provinces into a protectorate of England (Treaty of Nonsuch, 1585), and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648.
Question: What treaty gave England sovereignty over the United provinces?

Output: unanswerable

Input: Read this: The western section of the state is part of the Appalachian Mountain range. Among the subranges of the Appalachians located in the state are the Great Smoky Mountains, Blue Ridge Mountains, Great Balsam Mountains, and Black Mountains. The Black Mountains are the highest in the eastern United States, and culminate in Mount Mitchell at 6,684 feet (2,037 m) the highest point east of the Mississippi River. Although agriculture still remains important, tourism has become a dominant industry in the mountains. Growing Christmas trees has recently become an important industry as well. Because of the higher altitude, the climate in the mountains often differs markedly from that of the rest of the state. Winter in western North Carolina typically features high snowfall and subfreezing temperatures more akin to those of a midwestern state than of a southern state.
Question: The Great Smokey Mountains and the Black Moutains are subranges of what mountains?

Output: Appalachians

Input: Read this: The final is normally held the Saturday after the Premier League season finishes in May. The only seasons in recent times when this pattern was not followed were 19992000, when most rounds were played a few weeks earlier than normal as an experiment, and 201011 and 201213 when the FA Cup Final was played before the Premier League season had finished, to allow Wembley Stadium to be ready for the UEFA Champions League final, as well as in 201112 to allow England time to prepare for that summer's European Championships.
Question: When was the final played early so that England could prepare for the UEFA Champions League?

Output: unanswerable

Input: Read this: Stressful life experiences may be a cause of memory loss as a person ages. Glucocorticoids that are released during stress damage neurons that are located in the hippocampal region of the brain. Therefore, the more stressful situations that someone encounters, the more susceptible they are to memory loss later on. The CA1 neurons found in the hippocampus are destroyed due to glucocorticoids decreasing the release of glucose and the reuptake of glutamate. This high level of extracellular glutamate allow calcium to enter NMDA receptors which in return kills neurons. Stressful life experiences can also cause repression of memories where a person moves an unbearable memory to the unconscious mind. This directly relates to traumatic events in one's past such as kidnappings, being prisoners of war or sexual abuse as a child.
Question: What is the cause of neuron gain due to stress?
