Question: Extract the answer to the question from the following context. Question: What acts as a protective barrier for the brain? 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.
Answer: skull and meninges
[Q]: Extract the answer to the question from the following context. Question: What is missing from the history? Context: Romila Thapar notes that the division into Hindu-Muslim-British periods of Indian history gives too much weight to "ruling dynasties and foreign invasions", neglecting the social-economic history which often showed a strong continuity. The division into Ancient-Medieval-Modern periods overlooks the fact that the Muslim conquests occurred gradually during which time many things came and went off, while the south was never completely conquered. According to Thapar, a periodisation could also be based on "significant social and economic changes", which are not strictly related to a change of ruling powers.[note 1]

input: Please answer the following: Extract the answer to the question from the following context. Question: Who went to the countryside? Context: The Prussian Army, under the terms of the armistice, held a brief victory parade in Paris on 17 February; the city was silent and draped with black and the Germans quickly withdrew. Bismarck honoured the armistice, by allowing train loads of food into Paris and withdrawing Prussian forces to the east of the city, prior to a full withdrawal once France agreed to pay a five billion franc war indemnity. At the same time, Prussian forces were concentrated in the provinces of Alsace and Lorraine. An exodus occurred from Paris as some 200,000 people, predominantly middle-class, went to the countryside.

The Boston Symphony Orchestra is one of the "Big Five," a group of the greatest American orchestras, and the classical music magazine Gramophone called it one of the "world's best" orchestras. Symphony Hall (located west of Back Bay) is home to the Boston Symphony Orchestra, (and the related Boston Youth Symphony Orchestra, which is the largest youth orchestra in the nation) and the Boston Pops Orchestra. The British newspaper The Guardian called Boston Symphony Hall "one of the top venues for classical music in the world," adding that "Symphony Hall in Boston was where science became an essential part of concert hall design." Other concerts are held at the New England Conservatory's Jordan Hall. The Boston Ballet performs at the Boston Opera House. Other performing-arts organizations located in the city include the Boston Lyric Opera Company, Opera Boston, Boston Baroque (the first permanent Baroque orchestra in the US), and the Handel and Haydn Society (one of the oldest choral companies in the United States). The city is a center for contemporary classical music with a number of performing groups, several of which are associated with the city's conservatories and universities. These include the Boston Modern Orchestra Project and Boston Musica Viva. Several theaters are located in or near the Theater District south of Boston Common, including the Cutler Majestic Theatre, Citi Performing Arts Center, the Colonial Theater, and the Orpheum Theatre.

input: Please answer the following: Extract the answer to the question from the following context. Question: What was one of the topics being discussed at the panel discussion? Context: During a panel discussion at Harvard University's reunion for African American alumni during the 200304 academic year, two prominent black professors at the institutionLani Guinier and Henry Louis Gatespointed out an unintended effect of affirmative action policies at Harvard. They stated that only about a third of black Harvard undergraduates were from families in which all four grandparents were born into the African American community. The majority of black students at Harvard were Caribbean and African immigrants or their children, with some others the mixed-race children of biracial couples. One Harvard student, born in the South Bronx to a black family whose ancestors have been in the United States for multiple generations, said that there were so few Harvard students from the historic African American community that they took to calling themselves "the descendants" (i.e., descendants of American slaves). The reasons for this underrepresentation of historic African Americans, and possible remedies, remain a subject of debate.
