input question: Extract the answer to the question from the following context. Question: Why was the mosaic named Navicella? Context: The great Navicella mosaic (13051313) in the atrium of the Old St. Peter's is attributed to Giotto di Bondone. The giant mosaic, commissioned by Cardinal Jacopo Stefaneschi, was originally situated on the eastern porch of the old basilica and occupied the whole wall above the entrance arcade facing the courtyard. It depicted St. Peter walking on the waters. This extraordinary work was mainly destroyed during the construction of the new St. Peter's in the 17th century. Navicella means "little ship" referring to the large boat which dominated the scene, and whose sail, filled by the storm, loomed over the horizon. Such a natural representation of a seascape was known only from ancient works of art.???

input question: Extract the answer to the question from the following context. Question: What can happen to the edges of the disc's? Context: CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.???
output answer: sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits

input question: Extract the answer to the question from the following context. Question: What may make a person believe that someone is not an American even though they are? Context: In 1988, the civil rights leader Jesse Jackson urged Americans to use instead the term "African American" because it had a historical cultural base and was a construction similar to terms used by European descendants, such as German American, Italian American, etc. Since then, African American and black have often had parallel status. However, controversy continues over which if any of the two terms is more appropriate. Maulana Karenga argues that the term African-American is more appropriate because it accurately articulates their geographical and historical origin.[citation needed] Others have argued that "black" is a better term because "African" suggests foreignness, although Black Americans helped found the United States. Still others believe that the term black is inaccurate because African Americans have a variety of skin tones. Some surveys suggest that the majority of Black Americans have no preference for "African American" or "Black", although they have a slight preference for "black" in personal settings and "African American" in more formal settings.???
output answer: African American
