Problem: I know that the answer to the question "What were researchers looking for?" is in "There is some evidence, in the form of ice cores drilled to about 400 m (1,300 ft) above the water line, that Lake Vostok's waters may contain microbial life. The frozen surface of the lake shares similarities with Jupiter's moon, Europa. If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. On 7 February 2008, a NASA team embarked on a mission to Lake Untersee, searching for extremophiles in its highly alkaline waters. If found, these resilient creatures could further bolster the argument for extraterrestrial life in extremely cold, methane-rich environments.". Can you tell me what it is?

A: microbial life

Problem: I know that the answer to the question "what is the last ethnicity mentioned?" is in "Although critics have blamed Napoleon for several tactical mistakes preceding the battle, they have also praised his audacity for selecting a risky campaign strategy, choosing to invade the Italian peninsula from the north when the vast majority of French invasions came from the west, near or along the coastline. As Chandler points out, Napoleon spent almost a year getting the Austrians out of Italy in his first campaign; in 1800, it took him only a month to achieve the same goal. German strategist and field marshal Alfred von Schlieffen concluded that "Bonaparte did not annihilate his enemy but eliminated him and rendered him harmless" while "[attaining] the object of the campaign: the conquest of North Italy."".

Problem: I know that the answer to the question "How is the hall viewed internationally?" is in "Music is cherished in Boston. 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.".
