Question: "Why are RLVs purple-blue?" Context: "The only cosmetic difference between an RLV disc and a regular factory-pressed LaserDiscs is their reflective purple-violet (or blue with some RLV discs) color resulting from the dye embedded in the reflective layer of the disc to make it recordable, as opposed to the silver mirror appearance of regular LDs. The purplish color of RLVs is very similar to DVD-R and DVD+R discs. RLVs were popular for making short-run quantities of LaserDiscs for specialized applications such as interactive kiosks and flight simulators." Answer:
Ans: dye embedded in the reflective layer

Question: "What kind of prayer is spoken about in the Quran?" Context: "Belief is a fundamental aspect of morality in the Quran, and scholars have tried to determine the semantic contents of "belief" and "believer" in the Quran. The ethico-legal concepts and exhortations dealing with righteous conduct are linked to a profound awareness of God, thereby emphasizing the importance of faith, accountability, and the belief in each human's ultimate encounter with God. People are invited to perform acts of charity, especially for the needy. Believers who "spend of their wealth by night and by day, in secret and in public" are promised that they "shall have their reward with their Lord; on them shall be no fear, nor shall they grieve". It also affirms family life by legislating on matters of marriage, divorce, and inheritance. A number of practices, such as usury and gambling, are prohibited. The Quran is one of the fundamental sources of Islamic law (sharia). Some formal religious practices receive significant attention in the Quran including the formal prayers (salat) and fasting in the month of Ramadan. As for the manner in which the prayer is to be conducted, the Quran refers to prostration. The term for charity, zakat, literally means purification. Charity, according to the Quran, is a means of self-purification." Answer:
Ans: prostration

Question: "What purpose does Kingdom Hall serve?" Context: "Meetings for worship and study are held at Kingdom Halls, which are typically functional in character, and do not contain religious symbols. Witnesses are assigned to a congregation in whose "territory" they usually reside and attend weekly services they refer to as "meetings" as scheduled by congregation elders. The meetings are largely devoted to study of Watch Tower Society literature and the Bible. The format of the meetings is established by the religion's headquarters, and the subject matter for most meetings is the same worldwide. Congregations meet for two sessions each week comprising five distinct meetings that total about three-and-a-half hours, typically gathering mid-week (three meetings) and on the weekend (two meetings). Prior to 2009, congregations met three times each week; these meetings were condensed, with the intention that members dedicate an evening for "family worship". Gatherings are opened and closed with kingdom songs (hymns) and brief prayers. Twice each year, Witnesses from a number of congregations that form a "circuit" gather for a one-day assembly. Larger groups of congregations meet once a year for a three-day "regional convention", usually at rented stadiums or auditoriums. Their most important and solemn event is the commemoration of the "Lord's Evening Meal", or "Memorial of Christ's Death" on the date of the Jewish Passover." Answer:
Ans: typically functional in character

Question: "what did they send back to earth while they were up there?" Context: "On December 21, 1968, Frank Borman, James Lovell, and William Anders became the first humans to ride the Saturn V rocket into space on Apollo 8. They also became the first to leave low-Earth orbit and go to another celestial body, and entered lunar orbit on December 24. They made ten orbits in twenty hours, and transmitted one of the most watched TV broadcasts in history, with their Christmas Eve program from lunar orbit, that concluded with a reading from the biblical Book of Genesis. Two and a half hours after the broadcast, they fired their engine to perform the first trans-Earth injection to leave lunar orbit and return to the Earth. Apollo 8 safely landed in the Pacific ocean on December 27, in NASA's first dawn splashdown and recovery." Answer:
