Input: Read this: Being a city on the Ill and close to the Rhine, Strasbourg has always been an important centre of fluvial navigation, as is attested by archeological findings. In 1682 the Canal de la Bruche was added to the river navigations, initially to provide transport for sandstone from quarries in the Vosges for use in the fortification of the city. That canal has since closed, but the subsequent Canal du Rhone au Rhine, Canal de la Marne au Rhin and Grand Canal d'Alsace are still in use, as is the important activity of the Port autonome de Strasbourg. Water tourism inside the city proper attracts hundreds of thousands of tourists yearly.
Question: Which canal attracts the fewest tourists?

Output: unanswerable


QUES: Excess water intake, without replenishment of sodium and potassium salts, leads to hyponatremia, which can further lead to water intoxication at more dangerous levels. A well-publicized case occurred in 2007, when Jennifer Strange died while participating in a water-drinking contest. More usually, the condition occurs in long-distance endurance events (such as marathon or triathlon competition and training) and causes gradual mental dulling, headache, drowsiness, weakness, and confusion; extreme cases may result in coma, convulsions, and death. The primary damage comes from swelling of the brain, caused by increased osmosis as blood salinity decreases. Effective fluid replacement techniques include water aid stations during running/cycling races, trainers providing water during team games, such as soccer, and devices such as Camel Baks, which can provide water for a person without making it too hard to drink the water.

In 2007, what kind of contest was Jennifer Strange participating in upon her death?
What is the answer?
ANS: water-drinking

Rajasthan attracted 14 percent of total foreign visitors during 2009–2010 which is the fourth highest among Indian states. It is fourth also in Domestic tourist visitors. Tourism is a flourishing industry in Rajasthan. The palaces of Jaipur and Ajmer-Pushkar, the lakes of Udaipur, the desert forts of Jodhpur, Taragarh Fort (Star Fort) in Ajmer, and Bikaner and Jaisalmer rank among the most preferred destinations in India for many tourists both Indian and foreign. Tourism accounts for eight percent of the state's domestic product. Many old and neglected palaces and forts have been converted into heritage hotels. Tourism has increased employment in the hospitality sector.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How much of the GDP does hospitality employment account for?
Ah, so.. unanswerable


Question: During the three years following its inception, the university bore three different names. The board first approved "Eliot Seminary," but William Eliot was uncomfortable with naming a university after himself and objected to the establishment of a seminary, which would implicitly be charged with teaching a religious faith. He favored a nonsectarian university. In 1854, the Board of Trustees changed the name to "Washington Institute" in honor of George Washington. Naming the University after the nation's first president, only seven years before the American Civil War and during a time of bitter national division, was no coincidence. During this time of conflict, Americans universally admired George Washington as the father of the United States and a symbol of national unity. The Board of Trustees believed that the university should be a force of unity in a strongly divided Missouri. In 1856, the University amended its name to "Washington University." The university amended its name once more in 1976, when the Board of Trustees voted to add the suffix "in St. Louis" to distinguish the university from the nearly two dozen other universities bearing Washington's name.
Try to answer this question if possible: When was the name Washington University amended? 
Answer: 1856


Problem: In the United States, the term "treaty" has a different, more restricted legal sense than exists in international law. United States law distinguishes what it calls treaties from executive agreement, congressional-executive agreements, and sole executive agreements. All four classes are equally treaties under international law; they are distinct only from the perspective of internal American law. The distinctions are primarily concerning their method of approval. Whereas treaties require advice and consent by two-thirds of the Senators present, sole executive agreements may be executed by the President acting alone. Some treaties grant the President the authority to fill in the gaps with executive agreements, rather than additional treaties or protocols. And finally, congressional-executive agreements require majority approval by both the House and the Senate, either before or after the treaty is signed by the President.
Under US law, what primarily distinguishes treaties, executive agreements, congressional-executive agreements, and sole executive agreements?
---
Answer:
their method of approval
