Problem: Egypt:

Egypt has a developed energy market based on coal, oil, natural gas, and hydro power. Substantial coal deposits in the northeast Sinai are mined at the rate of about 600,000 tonnes (590,000 long tons; 660,000 short tons) per year. Oil and gas are produced in the western desert regions, the Gulf of Suez, and the Nile Delta. Egypt has huge reserves of gas, estimated at 2,180 cubic kilometres (520 cu mi), and LNG up to 2012 exported to many countries. In 2013, the Egyptian General Petroleum Co (EGPC) said the country will cut exports of natural gas and tell major industries to slow output this summer to avoid an energy crisis and stave off political unrest, Reuters has reported. Egypt is counting on top liquid natural gas (LNG) exporter Qatar to obtain additional gas volumes in summer, while encouraging factories to plan their annual maintenance for those months of peak demand, said EGPC chairman, Tarek El Barkatawy. Egypt produces its own energy, but has been a net oil importer since 2008 and is rapidly becoming a net importer of natural gas.

How much coal is mine yearly in northeast Sinai?
---
A: 600,000 tonnes


Problem: Estonia:

In 1989, during the "Singing Revolution", in a landmark demonstration for more independence, more than two million people formed a human chain stretching through Lithuania, Latvia and Estonia, called the Baltic Way. All three nations had similar experiences of occupation and similar aspirations for regaining independence. The Estonian Sovereignty Declaration was issued on 16 November 1988. On 20 August 1991, Estonia declared formal independence during the Soviet military coup attempt in Moscow, reconstituting the pre-1940 state. The Soviet Union recognised the independence of Estonia on 6 September 1991. The first country to diplomatically recognise Estonia's reclaimed independence was Iceland. The last units of the Russian army left on 31 August 1994.

What year did the Singing Revolution occur?
