Input: Article: The Warsaw Pact (formally, the Treaty of Friendship, Co-operation, and Mutual Assistance, sometimes, informally WarPac, akin in format to NATO) was a collective defense treaty among Soviet Union and seven Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the Paris Pacts of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe.

Now answer this question: Which conflict was the impetus for the formation of the Pact?

Output: the Cold War

Input: Article: The Revolutionary War soldier Nathan Hale (Yale 1773) was the prototype of the Yale ideal in the early 19th century: a manly yet aristocratic scholar, equally well-versed in knowledge and sports, and a patriot who "regretted" that he "had but one life to lose" for his country. Western painter Frederic Remington (Yale 1900) was an artist whose heroes gloried in combat and tests of strength in the Wild West. The fictional, turn-of-the-20th-century Yale man Frank Merriwell embodied the heroic ideal without racial prejudice, and his fictional successor Frank Stover in the novel Stover at Yale (1911) questioned the business mentality that had become prevalent at the school. Increasingly the students turned to athletic stars as their heroes, especially since winning the big game became the goal of the student body, and the alumni, as well as the team itself.

Now answer this question: What were the subjects of Frederic Remington's paintings?

Output: heroes gloried in combat and tests of strength in the Wild West

Input: Article: There are many non-incandescent light sources, such as the fluorescent lamp, high-intensity discharge lamps and LED lamps, which have higher luminous efficiency, and some have been designed to be retrofitted in fixtures for incandescent lights. These devices produce light by luminescence. These lamps produce discrete spectral lines and do not have the broad "tail" of invisible infrared emissions. By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution, the spectrum emitted can be tuned to mimic the appearance of incandescent sources, or other different color temperatures of white light. Due to the discrete spectral lines rather than a continuous spectrum, the light is not ideal for applications such as photography and cinematography.

Now answer this question: How can luminescent light sources be modified to resemble the appearance of incandescents?

Output:
By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution
