Article: From the mid-1950s through the 1960s, in the U.S. the common home record player or "stereo" (after the introduction of stereo recording) would typically have had these features: a three- or four-speed player (78, 45, 33 1⁄3, and sometimes 16 2⁄3 rpm); with changer, a tall spindle that would hold several records and automatically drop a new record on top of the previous one when it had finished playing, a combination cartridge with both 78 and microgroove styli and a way to flip between the two; and some kind of adapter for playing the 45s with their larger center hole. The adapter could be a small solid circle that fit onto the bottom of the spindle (meaning only one 45 could be played at a time) or a larger adaptor that fit over the entire spindle, permitting a stack of 45s to be played.

Question: What format was less common but could sometimes be found on home stereos?
Ans: 16 2⁄3 rpm


Article: Many ancient works, such as the Bible and the Greek tragedies,[citation needed] survive in hundreds of copies, and the relationship of each copy to the original may be unclear. Textual scholars have debated for centuries which sources are most closely derived from the original, hence which readings in those sources are correct.[citation needed] Although biblical books that are letters, like Greek plays, presumably had one original, the question of whether some biblical books, like the Gospels, ever had just one original has been discussed. Interest in applying textual criticism to the Qur'an has also developed after the discovery of the Sana'a manuscripts in 1972, which possibly date back to the 7–8th centuries.

Question: What manuscripts prompted a textual analysis of the Qur'an
Ans: Sana'a manuscripts

Article: Some succeeded their fathers as rulers, such as Sultan Ahmad al-Mansur, who ruled Morocco from 1578 to 1608. He was not technically considered as a mixed-race child of a slave; his mother was Fulani and a concubine of his father. Such tolerance for black persons, even when technically "free", was not so common in Morocco. The long association of sub-Saharan peoples as slaves is shown in the term abd (Arabic: عبد‎,) (meaning "slave"); it is still frequently used in the Arabic-speaking world as a term for black people.

Question: When did Sultan Ahmad al-Mansur rule?
Ans:
from 1578 to 1608
