In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Q: What happened to Santa Pudenziana?, Context: With the building of Christian basilicas in the late 4th century, wall and ceiling mosaics were adopted for Christian uses. The earliest examples of Christian basilicas have not survived, but the mosaics of Santa Constanza and Santa Pudenziana, both from the 4th century, still exist. The winemaking putti in the ambulatory of Santa Constanza still follow the classical tradition in that they represent the feast of Bacchus, which symbolizes transformation or change, and are thus appropriate for a mausoleum, the original function of this building. In another great Constantinian basilica, the Church of the Nativity in Bethlehem the original mosaic floor with typical Roman geometric motifs is partially preserved. The so-called Tomb of the Julii, near the crypt beneath St Peter's Basilica, is a 4th-century vaulted tomb with wall and ceiling mosaics that are given Christian interpretations. The Rotunda of Galerius in Thessaloniki, converted into a Christian church during the course of the 4th century, was embellished with very high artistic quality mosaics. Only fragments survive of the original decoration, especially a band depicting saints with hands raised in prayer, in front of complex architectural fantasies.

A: The Rotunda of Galerius in Thessaloniki

Q: What do methodist's change from normal communion?, Context: Historically, the Methodist Church has supported the temperance movement. John Wesley warned against the dangers of drinking in his famous sermon, "The Use of Money," and in his letter to an alcoholic. At one time, Methodist ministers had to take a pledge not to drink and encouraged their congregations to do the same. Today the United Methodist Church states that it "affirms our long-standing support of abstinence from alcohol as a faithful witness to God's liberating and redeeming love for persons." In fact, the United Methodist Church uses unfermented grape juice in the sacrament of Holy Communion, thus "expressing pastoral concern for recovering alcoholics, enabling the participation of children and youth, and supporting the church's witness of abstinence." Moreover, in 2011 and 2012, The United Methodist Church's General Board of Church and Society called on all United Methodists to abstain from alcohol for Lent.

A: uses unfermented grape juice

Q: What was used to create a pigment that could change color?, Context: The painters of the early Renaissance used two traditional lake pigments, made from mixing dye with either chalk or alum, kermes lake, made from kermes insects, and madder lake, made from the rubia tinctorum plant. With the arrival of cochineal, they had a third, carmine, which made a very fine crimson, though it had a tendency to change color if not used carefully. It was used by almost all the great painters of the 15th and 16th centuries, including Rembrandt, Vermeer, Rubens, Anthony van Dyck, Diego Velázquez and Tintoretto. Later it was used by Thomas Gainsborough, Seurat and J.M.W. Turner.

A:
cochineal
