Problem: Dissolution of the Soviet Union:

In late February, large public rallies took place in Kiev to protest the election laws, on the eve of the March 26 elections to the USSR Congress of People's Deputies, and to call for the resignation of the first secretary of the Communist Party of Ukraine, Volodymyr Scherbytsky, lampooned as "the mastodon of stagnation." The demonstrations coincided with a visit to Ukraine by Soviet President Gorbachev. On February 26, 1989, between 20,000 and 30,000 people participated in an unsanctioned ecumenical memorial service in Lviv, marking the anniversary of the death of 19th Century Ukrainian artist and nationalist Taras Shevchenko.

Problem: Serbo-Croatian:

South Slavic dialects historically formed a continuum. The turbulent history of the area, particularly due to expansion of the Ottoman Empire, resulted in a patchwork of dialectal and religious differences. Due to population migrations, Shtokavian became the most widespread in the western Balkans, intruding westwards into the area previously occupied by Chakavian and Kajkavian (which further blend into Slovenian in the northwest). Bosniaks, Croats and Serbs differ in religion and were historically often part of different cultural circles, although a large part of the nations have lived side by side under foreign overlords. During that period, the language was referred to under a variety of names, such as "Slavic", "Illyrian", or according to region, "Bosnian", "Serbian" and "Croatian", the latter often in combination with "Slavonian" or "Dalmatian".

What were some of the names given to language during period of foreign control?
---
A: "Slavic", "Illyrian", or according to region, "Bosnian", "Serbian" and "Croatian"

Problem: Liberia:

The Republic of Liberia, beginning as a settlement of the American Colonization Society (ACS), declared its independence on July 26, 1847. The United States did not recognize Liberia's independence until during the American Civil War on February 5, 1862. Between January 7, 1822 and the American Civil War, more than 15,000 freed and free-born Black Americans from United States and 3,198 Afro-Caribbeans relocated to the settlement. The Black American settlers carried their culture with them to Liberia. The Liberian constitution and flag were modeled after the United States. In January 3, 1848 Joseph Jenkins Roberts, a wealthy free-born Black American from Virginia who settled in Liberia, was elected as Liberia's first president after the people proclaimed independence.
