Article: A commutated DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutator, a long-lasting rotary electrical switch that periodically reverses the flow of current in the rotor windings as the shaft rotates. Thus, every brushed DC motor has AC flowing through its rotating windings. Current flows through one or more pairs of brushes that bear on the commutator; the brushes connect an external source of electric power to the rotating armature.

Question: What type of current is featured in brushed DC motors?
Ans: AC


Article: On April 23, 2008, against the Colorado Rockies, the Cubs recorded the 10,000th regular-season win in their franchise's history dating back to the beginning of the National League in 1876. The Cubs reached the milestone with an overall National League record of 10,000-9,465. Chicago was only the second club in Major League Baseball history to attain this milestone, the first having been the San Francisco Giants in mid-season 2005. The Cubs, however, hold the mark for victories for a team in a single city. The Chicago club's 77–77 record in the National Association (1871, 1874–1875) is not included in MLB record keeping. Post-season series are also not included in the totals. To honor the milestone, the Cubs flew an extra white flag displaying "10,000" in blue, along with the customary "W" flag.

Question: When was the beginning of the National League?
Ans: 1876


Article: The most impressive and famous of Sumerian buildings are the ziggurats, large layered platforms which supported temples. Sumerian cylinder seals also depict houses built from reeds not unlike those built by the Marsh Arabs of Southern Iraq until as recently as 400 CE. The Sumerians also developed the arch, which enabled them to develop a strong type of dome. They built this by constructing and linking several arches. Sumerian temples and palaces made use of more advanced materials and techniques,[citation needed] such as buttresses, recesses, half columns, and clay nails.

Question: Where were the use of advanced materials and techniques on display in Sumer?
Ans: Sumerian temples and palaces


Article: In the light of Mother F. A. Forbes research and reference to Pope Saint Gregory's writings, it would appear that Athanasius was constrained to be Bishop: She writes that when the Patriarch Alexander was on his death-bed he called Athanasius, who fled fearing he would be constrained to be made Bishop. "When the Bishops of the Church assembled to elect their new Patriarch, the whole Catholic population surrounded the church, holding up their hands to Heaven and crying; "Give us Athanasius!" The Bishops had nothing better. Athanasius was thus elected, as Gregory tells us..." (Pope Gregory I, would have full access to the Vatican Archives).

Question: Who did the Catholics of Alexandria want as their Bishop?
Ans:
"Give us Athanasius!"
