Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Uranium is a naturally occurring element that can be found in low levels within all rock, soil, and water. Uranium is the 51st element in order of abundance in the Earth's crust. Uranium is also the highest-numbered element to be found naturally in significant quantities on Earth and is almost always found combined with other elements. Along with all elements having atomic weights higher than that of iron, it is only naturally formed in supernovae. The decay of uranium, thorium, and potassium-40 in the Earth's mantle is thought to be the main source of heat that keeps the outer core liquid and drives mantle convection, which in turn drives plate tectonics.
Along with potassium-40 and uranium, the decay of what element is a primary cooling source driving plate tectonics?
A: unanswerable


Context and question: There are nevertheless a number of contemporary hunter-gatherer peoples who, after contact with other societies, continue their ways of life with very little external influence. One such group is the Pila Nguru (Spinifex people) of Western Australia, whose habitat in the Great Victoria Desert has proved unsuitable for European agriculture (and even pastoralism).[citation needed] Another are the Sentinelese of the Andaman Islands in the Indian Ocean, who live on North Sentinel Island and to date have maintained their independent existence, repelling attempts to engage with and contact them.[citation needed]
What is the name of the Spinifex people?
Answer: Pila Nguru

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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the population of the island start to steadily decline?
Ah, so..
late 1980s
