Question: Passage: In the Romantic era, the modern piano, with a more powerful, sustained tone and a wider range took over from the more delicate-sounding fortepiano. In the orchestra, the existing Classical instruments and sections were retained (string section, woodwinds, brass and percussion), but these sections were typically expanded to make a fuller, bigger sound. For example, while a Baroque orchestra may have had two double bass players, a Romantic orchestra could have as many as ten. "As music grew more expressive, the standard orchestral palette just wasn't rich enough for many Romantic composers."  New woodwind instruments were added, such as the contrabassoon, bass clarinet and piccolo and new percussion instruments were added, including xylophones, drums, celestes (a bell-like keyboard instrument), large orchestral harps, bells, and triangles  and even wind machines for sound effects. Question: What is a celestes?

Answer: a bell-like keyboard instrument


Question: Passage: The province of France has produced a large number of preachers. The conferences of Notre-Dame-de-Paris were inaugurated by Père Lacordaire. The Dominicans of the province of France furnished Lacordaire (1835–1836, 1843–1851), Jacques Monsabré (1869–1870, 1872–1890), Joseph Ollivier (1871, 1897), Thomas Etourneau (1898–1902).[citation needed] Since 1903 the pulpit of Notre Dame has been occupied by a succession of Dominicans. Père Henri Didon (d. 1900) was a Dominican. The house of studies of the province of France publishes L'Année Dominicaine (founded 1859), La Revue des Sciences Philosophiques et Theologiques (1907), and La Revue de la Jeunesse (1909). French Dominicans founded and administer the École Biblique et Archéologique française de Jérusalem founded in 1890 by Père Marie-Joseph Lagrange O.P. (1855–1938), one of the leading international centres for Biblical research. It is at the École Biblique that the famed Jerusalem Bible (both editions) was prepared. Question: What was prepared at the Ecole Biblique?

Question: Passage: The Perpetual Virginity of Mary asserts Mary's real and perpetual virginity even in the act of giving birth to the Son of God made Man. The term Ever-Virgin (Greek ἀειπάρθενος) is applied in this case, stating that Mary remained a virgin for the remainder of her life, making Jesus her biological and only son, whose conception and birth are held to be miraculous. While the Orthodox Churches hold the position articulated in the Protoevangelium of James that Jesus' brothers and sisters are older children of Joseph the Betrothed, step-siblings from an earlier marriage that left him widowed, Roman Catholic teaching follows the Latin father Jerome in considering them Jesus' cousins. Question: Which doctrine describes the belief that Mary remained a virgin, even though she gave birth to Jesus?

Answer:
The Perpetual Virginity of Mary
