Input: Article: In Sweden, the Supreme Court and the Supreme Administrative Court respectively function as the highest courts of the land. The Supreme Administrative Court considers cases concerning disputes between individuals and administrative organs, as well as disputes among administrative organs, while the Supreme Court considers all other cases. The judges are appointed by the Government. In most cases, the Supreme Courts will only grant leave to appeal a case (prövningstillstånd) if the case involves setting a precedent in the interpretation of the law. Exceptions are issues where the Supreme Court is the court of first instance. Such cases include an application for a retrial of a criminal case in the light of new evidence, and prosecutions made against an incumbent minister of the Government for severe neglect of duty. If a lower court has to try a case which involves a question where there is no settled interpretation of the law, it can also refer the question to the relevant Supreme Court for an answer.

Now answer this question: The ability to appeal a case provided by Sweden's court system is called what?

Output: prövningstillstånd


Article: Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.

Question: How much of mined cooper has been extracted in the last 24 years?
Ans: more than half

The problem: Answer a question about this article:
Unit testing is a software development process that involves synchronized application of a broad spectrum of defect prevention and detection strategies in order to reduce software development risks, time, and costs. It is performed by the software developer or engineer during the construction phase of the software development lifecycle. Rather than replace traditional QA focuses, it augments it. Unit testing aims to eliminate construction errors before code is promoted to QA; this strategy is intended to increase the quality of the resulting software as well as the efficiency of the overall development and QA process.
What does Unit testing look to eliminate?
****
The answer: construction errors

Question: Read this and answer the question

Most French rulers since the Middle Ages made a point of leaving their mark on a city that, contrary to many other of the world's capitals, has never been destroyed by catastrophe or war. In modernising its infrastructure through the centuries, Paris has preserved even its earliest history in its street map.[citation needed] At its origin, before the Middle Ages, the city was composed around several islands and sandbanks in a bend of the Seine; of those, two remain today: the île Saint-Louis, the île de la Cité; a third one is the 1827 artificially created île aux Cygnes. Modern Paris owes much to its late 19th century Second Empire remodelling by the Baron Haussmann: many of modern Paris' busiest streets, avenues and boulevards today are a result of that city renovation. Paris also owes its style to its aligned street-fronts, distinctive cream-grey "Paris stone" building ornamentation, aligned top-floor balconies, and tree-lined boulevards. The high residential population of its city centre makes it much different from most other western global cities.

When was ile aux Cygnes created?
Answer:
1827
