Input: Pacific War
U.S. submarines accounted for 56% of the Japanese merchantmen sunk; mines or aircraft destroyed most of the rest. US submariners also claimed 28% of Japanese warships destroyed. Furthermore, they played important reconnaissance roles, as at the battles of the Philippine Sea (June 1944) and Leyte Gulf (October 1944) (and, coincidentally,[clarification needed] at Midway in June 1942), when they gave accurate and timely warning of the approach of the Japanese fleet. Submarines also rescued hundreds of downed fliers, including future U.S. president George H.W. Bush.

What was one of the important roles submarine played in the war?
Output: reconnaissance roles

Input: Adult contemporary music
This format often includes dance-pop (such as upbeat songs by Madonna, Cher, Gloria Estefan and Kylie Minogue), power pops (mainly by boybands such as Backstreet Boys and Westlife), and adult-oriented soft rock music that are ballad-driven (typically by Aerosmith[citation needed], The Eagles, Sting, Toto and The Moody Blues). Generally, Hot AC radio stations target their music output towards the 18-54 age group and a demographic audience of both men and women.

What genre of music is played by The Eagles?
Output: soft rock

Input: Film speed
The DIN system, officially DIN standard 4512 by Deutsches Institut für Normung (but still named Deutscher Normenausschuß (DNA) at this time), was published in January 1934. It grew out of drafts for a standardized method of sensitometry put forward by Deutscher Normenausschuß für Phototechnik as proposed by the committee for sensitometry of the Deutsche Gesellschaft für photographische Forschung since 1930 and presented by Robert Luther (de) (1868–1945) and Emanuel Goldberg (1881–1970) at the influential VIII. International Congress of Photography (German: Internationaler Kongreß für wissenschaftliche und angewandte Photographie) held in Dresden from August 3 to 8, 1931.

Who created the DIN system?
Output: Deutsches Institut für Normung

Input: Predation
A predator's effect on its prey species is hard to see in the short-term. However, if observed over a longer period of time, it is seen that the population of a predator will correlationally rise and fall with the population of its prey in a cycle similar to the boom and bust cycle of economics. If a predator overhunts its prey, the prey population will lower to numbers that are too scarce for the predators to find. This will cause the predator population to dip, decreasing the predation pressure on the prey population. The decrease in predators will allow the small number of prey left to slowly increase their population to somewhere around their previous abundance, which will allow the predator population to increase in response to the greater availability of resources. If a predator hunts its prey species to numbers too low to sustain the population in the short term, they can cause not only the extinction or extirpation of the prey but also the extinction of their own species, a phenomenon known as coextinction. This is a risk that wildlife conservationists encounter when introducing predators to prey that have not coevolved with the same or similar predators. This possibility depends largely on how well and how fast the prey species is able to adapt to the introduced predator. One way that this risk can be avoided is if the predator finds an alternative prey species or if an alternative prey species is introduced (something that ecologists and environmentalists try to avoid whenever possible). An alternative prey species would help to lift some of the predation pressure from the initial prey species, giving the population a chance to recover, however it does not guarantee that the initial prey species will be able to recover as the initial prey population may have been hunted to below sustainable numbers or to complete extinction.

Are predator's effects on prey easiest to see in the short-term or long-term?
Output:
longer period of time
