Q: Passage: The northern side of Miami includes Midtown, a district with a great mix of diversity with many West Indians, Hispanics, European Americans, bohemians, and artists. Edgewater, and Wynwood, are neighborhoods of Midtown and are made up mostly of high-rise residential towers and are home to the Adrienne Arsht Center for the Performing Arts. The wealthier residents usually live in the northeastern part, in Midtown, the Design District, and the Upper East Side, with many sought after 1920s homes and home of the MiMo Historic District, a style of architecture originated in Miami in the 1950s. The northern side of Miami also has notable African American and Caribbean immigrant communities such as Little Haiti, Overtown (home of the Lyric Theater), and Liberty City.

Q: Passage: The legendary religious zeal of the Normans was exercised in religious wars long before the First Crusade carved out a Norman principality in Antioch. They were major foreign participants in the Reconquista in Iberia. In 1018, Roger de Tosny travelled to the Iberian Peninsula to carve out a state for himself from Moorish lands, but failed. In 1064, during the War of Barbastro, William of Montreuil led the papal army and took a huge booty.

A: Where did the Normans carve out a principality before the First Crusade?

Q: Passage: Antarctica has no indigenous population and there is no evidence that it was seen by humans until the 19th century. However, belief in the existence of a Terra Australis—a vast continent in the far south of the globe to "balance" the northern lands of Europe, Asia and North Africa—had existed since the times of Ptolemy (1st century AD), who suggested the idea to preserve the symmetry of all known landmasses in the world. Even in the late 17th century, after explorers had found that South America and Australia were not part of the fabled "Antarctica", geographers believed that the continent was much larger than its actual size.

A:
When was Antarctica last seen by humans?
