Problem: United States Army:

Collective training at the unit level takes place at the unit's assigned station, but the most intensive training at higher echelons is conducted at the three combat training centers (CTC); the National Training Center (NTC) at Fort Irwin, California, the Joint Readiness Training Center (JRTC) at Fort Polk, Louisiana, and the Joint Multinational Training Center (JMRC) at the Hohenfels Training Area in Hohenfels, Germany. ARFORGEN is the Army Force Generation process approved in 2006 to meet the need to continuously replenish forces for deployment, at unit level, and for other echelons as required by the mission. Individual-level replenishment still requires training at a unit level, which is conducted at the continental US (CONUS) replacement center at Fort Bliss, in New Mexico and Texas, before their individual deployment.

Where is the Double Readiness Training Center located?

The Quran and Muhammad talked about racial equality and justice as in The Farewell Sermon. Tribal and nationalistic differences were discouraged. But after Muhammad's passing, the old tribal differences between the Arabs started to resurface. Following the RomanPersian Wars and the ByzantineSassanid Wars, deep rooted differences between Iraq, formally under the Persian Sassanid Empire, and Syria, formally under the Byzantine Empire, also existed. Each wanted the capital of the newly established Islamic State to be in their area. Previously, the second caliph Umar was very firm on the governors and his spies kept an eye on them. If he felt that a governor or a commander was becoming attracted to wealth, he had him removed from his position.
What area wanted the capital of the Islamic State to be outside their area?
A: unanswerable

Context and question: The newly invented Western Electric moving coil or dynamic microphone was part of the Wide Range System. It had a flatter audio response than the old style Wente condenser type and didn't require electronics installed in the microphone housing. Signals fed to the cutting head were pre-emphasized in the treble region to help override noise in playback. Groove cuts in the vertical plane were employed rather than the usual lateral cuts. The chief advantage claimed was more grooves per inch that could be crowded together, resulting in longer playback time. Additionally, the problem of inner groove distortion, which plagued lateral cuts, could be avoided with the vertical cut system. Wax masters were made by flowing heated wax over a hot metal disc thus avoiding the microscopic irregularities of cast blocks of wax and the necessity of planing and polishing.
How was wax used to improve recordings?
Answer: avoiding the microscopic irregularities

Question: The film library of Turner Entertainment would serve as the base form of programming for TCM upon the network's launch. Before the creation of Turner Classic Movies, films from Turner's library of movies aired on the Turner Broadcasting System's advertiser-supported cable network TNT along with colorized versions of black-and-white classics such as The Maltese Falcon. After the library was acquired, MGM/UA signed a deal with Turner to continue distributing the pre-May 1986 MGM and to begin distributing the pre-1950 Warner Bros. film libraries for video release (the rest of the library went to Turner Home Entertainment).
Is there an answer to this question: On what network did Turner Entertainment's film library air prior to the creation of MGM/UA?

Answer: unanswerable

The lower (Triassic) boundary is set by the PermianTriassic extinction event, during which approximately 90% to 96% of marine species and 70% of terrestrial vertebrates became extinct. It is also known as the "Great Dying" because it is considered the largest mass extinction in the Earth's history. The upper (Cretaceous) boundary is set at the CretaceousTertiary (KT) extinction event (now more accurately called the CretaceousPaleogene (or KPg) extinction event), which may have been caused by the impactor that created Chicxulub Crater on the Yucatan Peninsula. Towards the Late Cretaceous large volcanic eruptions are also believed to have contributed to the CretaceousPaleogene extinction event. Approximately 50% of all genera became extinct, including all of the non-avian dinosaurs.
What is the largest extinction of species in Earth's history known as?
A:
Great Dying
