Q: Successful mining took time and capital, particularly once most of the timber around the Klondike had been cut down. A realistic mining operation required $1,500 ($1.2 million) for wood to be burned to melt the ground, along with around $1,000 ($800,000) to construct a dam, $1,500 ($1.2 million) for ditches and up to $600 ($480,000) for sluice boxes, a total of $4,600. The attraction of the Klondike to a prospector, however, was that when gold was found, it was often highly concentrated. Some of the creeks in the Klondike were fifteen times richer in gold than those in California Gold Rush, and richer still than those in Witwatersrand Gold Rush. In just two years, for example, $230,000 ($184 million) worth of gold was brought up from claim 29 on the Eldorado Creek.
Which gold rushes were some of the Klondike creeks richer than?

A: California Gold Rush


Q: The Leaving Certificate, which is taken after two years of study, is the final examination in the secondary school system. Those intending to pursue higher education normally take this examination, with access to third-level courses generally depending on results obtained from the best six subjects taken, on a competitive basis. Third-level education awards are conferred by at least 38 Higher Education Institutions - this includes the constituent or linked colleges of seven universities, plus other designated institutions of the Higher Education and Training Awards Council. The Programme for International Student Assessment, coordinated by the OECD, currently ranks Ireland as having the fourth highest reading score, ninth highest science score and thirteenth highest mathematics score, among OECD countries, in its 2012 assessment. In 2012, Irish students aged 15 years had the second highest levels of reading literacy in the EU. Ireland also has 0.747 of the World's top 500 Universities per capita, which ranks the country in 8th place in the world. Primary, secondary and higher  level education are all free in Ireland for all EU citizens. There are charges to cover student services and examinations. In addition, 37 percent of Ireland's population has a university or college degree, which is among the highest percentages in the world.
How many ranks higher does Ireland rate among other OECD countries in mathematics compared to science?

A: 4

Q: When the area was disputed between Weimar Germany and the Second Polish Republic, the Poles recalled the massacre quoting the number of 10,000 murdered. After Nazi Germany had annexed the Free City of Danzig in World War II, the exiled Polish government in releases said that the knights had "massacre ten thousand souls", portrayed the contemporary Germans in the tradition of these events and linked these events with National Socialism. In 1969 the post-war Polish city authorities dedicated a monument that commemorates the massacre of the population of Gdańsk in 1308. Its stated aim was to propagate an analogy of the events of 1308 and the German crimes of World War II. On the monument, called Tym co za Polskość Gdańska , the dates 1308, 1454, 1466 and 1939 are mentioned, relating the events of 1308 to the Thirteen Years' War and World War II.
How many years after the population of Gdańsk was massacared was a momument errected to commemorate the event?

A:
661
