1. To find the answer to this question, we need to look at the history of the Eastern European revolutions of 1989. These revolutions were a series of anti-communist uprisings that took place in several countries in Eastern Europe, leading to the fall of communist regimes.

To determine which revolution was violent and bloody, we can examine each option:

A. Poland: The Polish revolution, known as the Polish Round Table Agreement, was relatively peaceful. It involved negotiations between the communist government and opposition groups, resulting in democratic reforms.

B. Hungary: The Hungarian revolution, known as the Hungarian Roundtable Negotiations, was also mostly peaceful. It included negotiations between the communist government and opposition groups, leading to democratic changes.

C. Czechoslovakia: The Czechoslovakian revolution, known as the Velvet Revolution, was a non-violent and mostly peaceful revolution. It involved mass protests and negotiations, resulting in the downfall of the communist government.

D. Romania: The Romanian revolution, known as the Romanian Revolution of 1989, was the only revolution among these options that turned violent and bloody. It started with protests against the oppressive regime of Nicolae Ceaușescu and escalated into violent clashes with security forces. Ceaușescu and his wife were tried and executed.

Therefore, the correct answer is D. Romania.

2. To determine when the Biafran War began in Nigeria, we need to consider the historical context and events surrounding the conflict.

A. After a countercoup by Nigerian Muslims seized the national government: This option does not align with the causes of the Biafran War. The war was primarily driven by ethnic tensions between the Igbo people in the southeastern region of Nigeria and the Nigerian government.

B. After Nigeria was divided into 19 small units: This option does not accurately describe the causes of the war. The conflict emerged from a demand for secession by the predominantly Igbo region, seeking to establish the independent state of Biafra.

C. With the death of the military dictator General Sani Abacha: This option is not correct. General Sani Abacha was a military dictator who ruled Nigeria in the 1990s, while the Biafran War took place from 1967 to 1970.

D. When an Ibo-led military council proclaimed a centralized dictatorship: This option accurately describes the start of the Biafran War. In 1966, an Igbo-led military coup took place in Nigeria, resulting in the establishment of a centralized government. This triggered tensions between the Igbo people and other ethnic groups, leading to the secession of Biafra and the subsequent war.

Therefore, the correct answer is D. When an Ibo-led military council proclaimed a centralized dictatorship.

3. To identify the demographic factors that contributed to the rise of the counterculture, we need to consider the social and cultural changes during the period in question.

A. Postwar prosperity meant that young people had significant purchasing power: This option is accurate. The economic prosperity that followed World War II allowed young people to have greater disposable income, contributing to the growth of the counterculture movement.

B. Mass communications and youth travel spread the counterculture over North America and Europe: This is also an accurate option. Advances in mass media and increased mobility facilitated the spread of countercultural ideas and practices across North America and Europe.

C. The use of LSD and other psychedelics led to widespread impulsive behavior: This option is incorrect. While drug use, including LSD, was prevalent in the counterculture movement, it did not necessarily lead to widespread impulsive behavior. The counterculture was driven by a desire for social and political change rather than impulsive behaviors.

D. The postwar baby boom meant that young people made up a large portion of the population: This option is accurate. The postwar baby boom resulted in a significant increase in the population of young people, giving them a larger presence and influence within society.

Therefore, the correct answer is C. The use of LSD and other psychedelics led to widespread impulsive behavior.

4. To determine the association between Juan Perón and a specific country, we need to examine the historical context and identify the leader's role in a particular nation.

A. Brazil: This option is incorrect. Juan Perón was not associated with Brazil. He was a prominent political figure in Argentina.

B. Paraguay: This option is incorrect. Juan Perón did not have a significant connection to Paraguay. He was primarily involved in Argentine politics.

C. Chile: This option is incorrect. Juan Perón was not associated with Chile. His political career and influence were centered in Argentina.

D. Venezuela: This option is incorrect. Juan Perón was not associated with Venezuela. His political activities and legacy were predominantly linked to Argentina.

Therefore, the correct answer is A. Argentina. Juan Perón was a major political figure in Argentina, serving as the President of Argentina for three non-consecutive terms from 1946 to 1955 and again from 1973 to 1974. Augusto Pinochet, on the other hand, was the military dictator of Chile from 1973 to 1990.
