 Passage 3:Scottish field armies rarely managed to stand up to the usually larger and more professional armies produced by England, but they were used to good effect by Robert I of Scotland at the Battle of Bannockburn in 1314 to secure Scottish independence. He adopted a policy of slighting castles and made use of naval power to support his forces, beginning to develop a royal Scottish naval force. In the Late Middle Ages under the Stewart kings these forces were further augmented by specialist troops, particularly men-at-arms and archers, hired by bonds of manrent, similar to English indentures of the same period. New "livery and maintenance" castles were built to house these troops and castles began to be adapted to accommodate gunpowder weapons. The Stewarts also adopted major innovations in continental warfare, such as longer pikes, the extensive use of artillery, and they built up a formidable navy. However, one of the best armed and largest Scottish armies ever assembled still met with defeat at the hands of an English army at the Battle of Flodden in 1513, which saw the destruction of a large number of ordinary troops, a large section of the nobility and King James IV.

Question: What triode invention came out first out of television, public address system, electric phonographs, and talking motion pictures? Passage 1:The discovery of the triode's amplifying ability in 1912 revolutionized electrical technology, creating the new field of electronics, the technology of active (amplifying) electrical devices. The triode was immediately applied to many areas of communication. Triode "continuous wave" radio transmitters replaced the cumbersome inefficient "damped wave" spark gap transmitters, allowing the transmission of sound by amplitude modulation (AM). Amplifying triode radio receivers, which had the power to drive loudspeakers, replaced weak crystal radios, which had to be listened to with earphones, allowing families to listen together. This resulted in the evolution of radio from a commercial message service to the first mass communication medium, with the beginning of radio broadcasting around 1920. Triodes made transcontinental telephone service possible. Vacuum tube triode repeaters, invented at Bell Telephone after its purchase of the Audion rights, allowed telephone calls to travel beyond the unamplified limit of about 800 miles. The opening by Bell of the first transcontinental telephone line was celebrated 3 years later, on January 25, 1915. Other inventions made possible by the triode were television, public address systems, electric phonographs, and talking motion pictures.
 Passage 2:Zuhayr belonged to the Bali tribe, itself part of the larger Quda'a confederation that was present throughout Syria and the northern Hejaz. He is considered by some Muslim sources, namely Ibn Hajar and al-Suyuti, as a sahabi (companion) of the Islamic prophet Muhammad, while al-Suyuti also places him with the second-generation of Muslims, known as the tabi'un. According to Ibn Hajar, Zuhayr participated in the Muslim conquest of Egypt in 639. He later served as a lieutenant commander in the army of Uqba ibn Nafi during the Muslim conquest of the Maghreb in 670. In that campaign, he played a role in the capture of Sirte and was made its governor. The Arabs established the town of Kairouan in Ifriqiya to garrison their troops and families and when Uqba advanced west of Kairouan, Zuhayr accompanied him. As Uqba campaigned in the region of Sous (in modern-day Morocco), he ordered Zuhayr to return with the majority of the Arab troops to Kairouan to defend the city from an impending Byzantine attack. 
 Passage 3:The Strategic Air Command (SAC) initially operated DC-130s assigned to its 100th Strategic Reconnaissance Wing (100 SRW) at Davis–Monthan AFB, Arizona from 1966 through 1976. In 1976, the 100th's DC-130s and drone assets were transferred to the 432nd Tactical Drone Group of Tactical Air Command (TAC) at Davis–Monthan AFB. Concurrent with this action, the 100 SRW's U-2 aircraft assets were transferred to the 9th Strategic Reconnaissance Wing (9 SRW) and merged with the latter's SR-71 aircraft assets at Beale AFB, California. The 100 SRW was then re-designated as the 100th Air Refueling Wing (100 ARW) and relocated to Beale AFB, operating KC-135 Stratotanker aircraft, until its later reassignment to its current home of RAF Mildenhall, United Kingdom.
