Problem: Estonian language:

When Estonia was invaded and occupied by the Soviet Union in World War II, the status of the Estonian language changed to the first of two official languages (Russian being the other one). As with Latvia many immigrants entered Estonia under Soviet encouragement. In the second half of the 1970s, the pressure of bilingualism (for Estonians) intensified, resulting in widespread knowledge of Russian throughout the country. The Russian language was termed as 'the language of friendship of nations' and was taught to Estonian children, sometimes as early as in kindergarten. Although teaching Estonian to non-Estonians in schools was compulsory, in practice learning the language was often considered unnecessary.

What became more intense in the 1970's in Estonia?

A: pressure of bilingualism

Problem: Capital punishment in the United States:

In 1977, the Supreme Court's Coker v. Georgia decision barred the death penalty for rape of an adult woman, and implied that the death penalty was inappropriate for any offense against another person other than murder. Prior to the decision, the death penalty for rape of an adult had been gradually phased out in the United States, and at the time of the decision, the State of Georgia and the U.S. Federal government were the only two jurisdictions to still retain the death penalty for that offense. However, three states maintained the death penalty for child rape, as the Coker decision only imposed a ban on executions for the rape of an adult woman. In 2008, the Kennedy v. Louisiana decision barred the death penalty for child rape. The result of these two decisions means that the death penalty in the United States is largely restricted to cases where the defendant took the life of another human being. The current federal kidnapping statute, however, may be exempt because the death penalty applies if the victim dies in the perpetrator's custody, not necessarily by his hand, thus stipulating a resulting death, which was the wording of the objection. In addition, the Federal government retains the death penalty for non-murder offenses that are considered crimes against the state, including treason, espionage, and crimes under military jurisdiction.

In what year was Coker v. Georgia decided?

A: 1977

Problem: Classical music:

During the Baroque era, keyboard music played on the harpsichord and pipe organ became increasingly popular, and the violin family of stringed instruments took the form generally seen today. Opera as a staged musical drama began to differentiate itself from earlier musical and dramatic forms, and vocal forms like the cantata and oratorio became more common. Vocalists began adding embellishments to melodies. Instrumental ensembles began to distinguish and standardize by size, giving rise to the early orchestra for larger ensembles, with chamber music being written for smaller groups of instruments where parts are played by individual (instead of massed) instruments. The concerto as a vehicle for solo performance accompanied by an orchestra became widespread, although the relationship between soloist and orchestra was relatively simple.

What did vocalist add to melodies beginning in the Baroque era?

A: embellishments

Problem: Near East:

Until about 1855 the words near east and far east did not refer to any particular region. The far East, a phrase containing a noun, East, qualified by an adjective, far, could be at any location in the "far east" of the speaker's home territory. The Ottoman Empire, for example, was the far East as much as the East Indies. The Crimean War brought a change in vocabulary with the introduction of terms more familiar to the late 19th century. The Russian Empire had entered a more aggressive phase, becoming militarily active against the Ottoman Empire and also against China, with territorial aggrandizement explicitly in mind. Rethinking its policy the British government decided that the two polities under attack were necessary for the balance of power. It therefore undertook to oppose the Russians in both places, one result being the Crimean War. During that war the administration of the British Empire began promulgating a new vocabulary, giving specific regional meaning to "the Near East," the Ottoman Empire, and "the Far East," the East Indies. The two terms were now compound nouns often shown hyphenated.
