Input: Predation
It is fairly clear that predators tend to lower the survival and fecundity of their prey, but on a higher level of organization, populations of predator and prey species also interact. It is obvious that predators depend on prey for survival, and this is reflected in predator populations being affected by changes in prey populations. It is not so obvious, however, that predators affect prey populations. Eating a prey organism may simply make room for another if the prey population is approaching its carrying capacity.

Predators lower what aspects of their prey?
Output: survival and fecundity

Input: The Blitz
Between 7 September 1940 and 21 May 1941, 16 British cities suffered aerial raids with at least 100 long tons of high explosives. Over a period of 267 days, London was attacked 71 times, Birmingham, Liverpool and Plymouth eight times, Bristol six, Glasgow five, Southampton four, Portsmouth and Hull three and a minimum of one large raid on eight other cities. This was a result of a rapid escalation starting on 24 August 1940, when night bombers aiming for RAF airfields drifted off course and accidentally destroyed several London homes, killing civilians, combined with the UK Prime Minister Winston Churchill's retaliatory bombing of Berlin on the following night.[clarification needed]

How many days did the aerial raids on Great Britain last?
Output: 267 days

Input: Copyright infringement
There have been instances where a country's government bans a movie, resulting in the spread of copied videos and DVDs. Romanian-born documentary maker Ilinca Calugareanu wrote a New York Times article telling the story of Irina Margareta Nistor, a narrator for state TV under Nicolae Ceausescu's regime. A visitor from the west gave her bootlegged copies of American movies, which she dubbed for secret viewings through Romania. According to the article, she dubbed more than 3,000 movies and became the country's second-most famous voice after Ceausescu, even though no one knew her name until many years later.

How many movies did Nistor dub for secret viewings in Romania?
Output: 3,000

Input: Estonia
In the first centuries AD, political and administrative subdivisions began to emerge in Estonia. Two larger subdivisions appeared: the province (Estonian: kihelkond) and the land (Estonian: maakond). Several elderships or villages made up a province. Nearly all provinces had at least one fortress. The king or other highest administrative official elder directed the defense of the local area. By the thirteenth century Estonia consisted of the following provinces: Revala, Harjumaa, Saaremaa, Hiiumaa, Laanemaa, Alempois, Sakala, Ugandi, Jogentagana, Soopoolitse, Vaiga, Mohu, Nurmekund, Jarvamaa and Virumaa.

When did political subgroups begin to appear in Estonia?
Output:
first centuries AD
