Input: United States Air Force
USAF rank is divided between enlisted airmen, non-commissioned officers, and commissioned officers, and ranges from the enlisted Airman Basic (E-1) to the commissioned officer rank of General (O-10). Enlisted promotions are granted based on a combination of test scores, years of experience, and selection board approval while officer promotions are based on time-in-grade and a promotion selection board. Promotions among enlisted personnel and non-commissioned officers are generally designated by increasing numbers of insignia chevrons. Commissioned officer rank is designated by bars, oak leaves, a silver eagle, and anywhere from one to four stars (one to five stars in war-time).[citation needed]

How are Officer promotions within the USAF decided?
Output: based on time-in-grade and a promotion selection board

Input: Transistor
The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony. The triode, however, was a fragile device that consumed a lot of power. Physicist Julius Edgar Lilienfeld filed a patent for a field-effect transistor (FET) in Canada in 1925, which was intended to be a solid-state replacement for the triode. Lilienfeld also filed identical patents in the United States in 1926 and 1928. However, Lilienfeld did not publish any research articles about his devices nor did his patents cite any specific examples of a working prototype. Because the production of high-quality semiconductor materials was still decades away, Lilienfeld's solid-state amplifier ideas would not have found practical use in the 1920s and 1930s, even if such a device had been built. In 1934, German inventor Oskar Heil patented a similar device.

What was the purpose of the thermionic triode?
Output: amplified radio technology and long-distance telephony

Input: Josip Broz Tito
Prime Minister Josip Broz Tito met with the president of the Bishops' Conference of Yugoslavia, Aloysius Stepinac on 4 June 1945, two days after his release from imprisonment. The two could not reach an agreement on the state of the Catholic Church. Under Stepinac's leadership, the bishops' conference released a letter condemning alleged Partisan war crimes in September, 1945. The following year Stepinac was arrested and put on trial. In October 1946, in its first special session for 75 years, the Vatican excommunicated Tito and the Yugoslav government for sentencing Stepinac to 16 years in prison on charges of assisting Ustase terror and of supporting forced conversions of Serbs to Catholicism. Stepinac received preferential treatment in recognition of his status and the sentence was soon shortened and reduced to house-arrest, with the option of emigration open to the archbishop. At the conclusion of the "Informbiro period", reforms rendered Yugoslavia considerably more religiously liberal than the Eastern Bloc states.

How long after his release from imprisonment did TIto attend the Bishops' Conference of Yugoslavia?
Output: two days

Input: Dell
In the early 1990s, Dell sold its products through Best Buy, Costco and Sam's Club stores in the United States. Dell stopped this practice in 1994, citing low profit-margins on the business, exclusively distributing through a direct-sales model for the next decade. In 2003, Dell briefly sold products in Sears stores in the U.S. In 2007, Dell started shipping its products to major retailers in the U.S. once again, starting with Sam's Club and Wal-Mart. Staples, the largest office-supply retailer in the U.S., and Best Buy, the largest electronics retailer in the U.S., became Dell retail partners later that same year.

What decade did Dell sell electronics through big box stores?
Output:
1990s
