Problem: In 1832, South Carolina passed an ordinance of nullification, a procedure by which a state could, in effect, repeal a federal law; it was directed against the most recent tariff acts. Soon, federal soldiers were dispensed to Charleston's forts, and five United States Coast Guard cutters were detached to Charleston Harbor "to take possession of any vessel arriving from a foreign port, and defend her against any attempt to dispossess the Customs Officers of her custody until all the requirements of law have been complied with." This federal action became known as the Charleston incident. The state's politicians worked on a compromise law in Washington to gradually reduce the tariffs.

Problem: Ethnic Russians constitute 25.5% of the country's current population and 58.6% of the native Estonian population is also able to speak Russian. In all, 67.8% of Estonia's population can speak Russian. Command of Russian language, however, is rapidly decreasing among younger Estonians (primarily being replaced by the command of English). For example, if 53% of ethnic Estonians between 15 and 19 claim to speak some Russian, then among the 10- to 14-year-old group, command of Russian has fallen to 19% (which is about one-third the percentage of those who claim to have command of English in the same age group).
How much of Estonia speaks Russian?
The answer is the following: 67.8%
