Article: Over subsequent centuries, many Presbyterian churches modified these prescriptions by introducing hymnody, instrumental accompaniment, and ceremonial vestments into worship. However, there is not one fixed "Presbyterian" worship style. Although there are set services for the "Lord's Day", one can find a service to be evangelical and even revivalist in tone (especially in some conservative denominations), or strongly liturgical, approximating the practices of Lutheranism or Anglicanism (especially where Scottish tradition is esteemed),[clarification needed] or semi-formal, allowing for a balance of hymns, preaching, and congregational participation (favored by probably most American Presbyterians). Most Presbyterian churches follow the traditional liturgical year and observe the traditional holidays, holy seasons, such as Advent, Christmas, Ash Wednesday, Holy Week, Easter, Pentecost, etc. They also make use of the appropriate seasonal liturgical colors, etc. Many, incorporate ancient liturgical prayers and responses into the communion services and follow a daily, seasonal, and festival lectionary. Other Presbyterians, however, such as the Reformed Presbyterians, would practice a cappella exclusive psalmody, as well as eschew the celebration of holy days.

Question: What do reformed Presbyterians practice?

Article: In the increasingly globalized film industry, videoconferencing has become useful as a method by which creative talent in many different locations can collaborate closely on the complex details of film production. For example, for the 2013 award-winning animated film Frozen, Burbank-based Walt Disney Animation Studios hired the New York City-based husband-and-wife songwriting team of Robert Lopez and Kristen Anderson-Lopez to write the songs, which required two-hour-long transcontinental videoconferences nearly every weekday for about 14 months.

Question: How many months did the songwriters work on the movie via videoconferencing?
Ans: 14

Article: In the Yoma tractate of the Babylonian Talmud the name Gomer is rendered as Germania, which elsewhere in rabbinical literature was identified with Germanikia in northwestern Syria, but later became associated with Germania. Ashkenaz is linked to Scandza/Scanzia, viewed as the cradle of Germanic tribes, as early as a 6th-century gloss to the Historia Ecclesiastica of Eusebius. In the 10th-century History of Armenia of Yovhannes Drasxanakertc'i (1.15) Ashkenaz was associated with Armenia, as it was occasionally in Jewish usage, where its denotation extended at times to Adiabene, Khazaria, Crimea and areas to the east. His contemporary Saadia Gaon identified Ashkenaz with the Saquliba or Slavic territories, and such usage covered also the lands of tribes neighboring the Slavs, and Eastern and Central Europe. In modern times, Samuel Krauss identified the Biblical "Ashkenaz" with Khazaria.

Question: Who identified Ashkenaz with the Saquliba or Slavic territories?
Ans:
Saadia Gaon
