Input: Read this: The Quine-Duhem thesis argues that it's impossible to test a single hypothesis on its own, since each one comes as part of an environment of theories. Thus we can only say that the whole package of relevant theories has been collectively falsified, but cannot conclusively say which element of the package must be replaced. An example of this is given by the discovery of the planet Neptune: when the motion of Uranus was found not to match the predictions of Newton's laws, the theory "There are seven planets in the solar system" was rejected, and not Newton's laws themselves. Popper discussed this critique of naive falsificationism in Chapters 3 and 4 of The Logic of Scientific Discovery. For Popper, theories are accepted or rejected via a sort of selection process. Theories that say more about the way things appear are to be preferred over those that do not; the more generally applicable a theory is, the greater its value. Thus Newton's laws, with their wide general application, are to be preferred over the much more specific "the solar system has seven planets".[dubious discuss]
Question: Why are Newton's laws not preferred over the other theory?

Output: unanswerable

Input: Read this: Although many species can reproduce asexually and use similar mechanisms to regenerate after severe injuries, sexual reproduction is the normal method in species whose reproduction has been studied. The minority of living polychaetes whose reproduction and lifecycles are known produce trochophore larvae, that live as plankton and then sink and metamorphose into miniature adults. Oligochaetes are full hermaphrodites and produce a ring-like cocoon around their bodies, in which the eggs and hatchlings are nourished until they are ready to emerge.
Question: What annelids make a cocoon in a pyramid around themselves?

Output: unanswerable

Input: Read this: During periods of unemployment, there has been a long pattern of emigration from the island since the post-Napoleonic period. The majority of "Saints" emigrated to the UK, South Africa and in the early years, Australia. The population has steadily declined since the late 1980s and has dropped from 5,157 at the 1998 census to 4,255 in 2008. In the past emigration was characterised by young unaccompanied persons leaving to work on long-term contracts on Ascension and the Falkland Islands, but since "Saints" were re-awarded UK citizenship in 2002, emigration to the UK by a wider range of wage-earners has accelerated due to the prospect of higher wages and better progression prospects.
Question: When did the population of the island start to steadily decline?

Output: late 1980s

Input: Read this: As a result, they broke up in 1979, but remained close friends. Then in 1984 they renewed their romance, and in November 1985, they married, already having had a son, Max Samuel.

They agreed to maintain homes near each other as to facilitate the shared custody and parenting of their son.:403 Their divorce was recorded as the third most costly celebrity divorce in history.
