Please answer this: Question: "What is surrounded by cerebrospinal fluid?" Context: "Another approach to brain function is to examine the consequences of damage to specific brain areas. Even though it is protected by the skull and meninges, surrounded by cerebrospinal fluid, and isolated from the bloodstream by the bloodbrain barrier, the delicate nature of the brain makes it vulnerable to numerous diseases and several types of damage. In humans, the effects of strokes and other types of brain damage have been a key source of information about brain function. Because there is no ability to experimentally control the nature of the damage, however, this information is often difficult to interpret. In animal studies, most commonly involving rats, it is possible to use electrodes or locally injected chemicals to produce precise patterns of damage and then examine the consequences for behavior."

Please answer this: Question: "What is the first name of the mandolin musician with the surname Krenek?" Context: "The mandolin orchestras never completely went away, however. In fact, along with all the other musical forms the mandolin is involved with, the mandolin ensemble (groups usually arranged like the string section of a modern symphony orchestra, with first mandolins, second mandolins, mandolas, mandocellos, mando-basses, and guitars, and sometimes supplemented by other instruments) continues to grow in popularity. Since the mid-nineties, several public-school mandolin-based guitar programs have blossomed around the country, including Fretworks Mandolin and Guitar Orchestra, the first of its kind. The national organization, Classical Mandolin Society of America, founded by Norman Levine, represents these groups. Prominent modern mandolinists and composers for mandolin in the classical music tradition include Samuel Firstman, Howard Fry, Rudy Cipolla, Dave Apollon, Neil Gladd, Evan Marshall, Marilynn Mair and Mark Davis (the Mair-Davis Duo), Brian Israel, David Evans, Emanuil Shynkman, Radim Zenkl, David Del Tredici and Ernst Krenek."

Please answer this: Question: "Which treaty was between France and the United States before 1780?" Context: "When revolutionary France declared war on Great Britain in 1793, the United States sought to remain neutral, but the Jay Treaty, which was favorable to Great Britain, angered the French government, which viewed it as a violation of the 1778 Treaty of Alliance. French privateers began to seize U.S. vessels, which led to an undeclared "Quasi-War" between the two nations. Fought at sea from 1798 to 1800, the United States won a string of victories in the Caribbean. George Washington was called out of retirement to head a "provisional army" in case of invasion by France, but President John Adams managed to negotiate a truce, in which France agreed to terminate the prior alliance and cease its attacks."
