Answer:
D. creation of a youth culture in the 1960s
Explanation:
The baby-boom was a demographic phenomenon that occurred after WWII, between 1946 and 1964, characterized by an increase in the birthrate. This increment was due to the unprecedented global economic growth that followed the war. Consequently, the young range of the population was larger during the 50s and 60s, which combined with economic development, created a new branch of consumers in the market: teenagers and young people. The new teenagers, most of them from the middle class who had access to jobs, demanded new cultural goods, like rock music, comics, movies, art, etc. Young people did not only entered in the public sphere as passive consumers, but also as active members of the civil society, demanding for different politics towards sex, drugs, the Vietnam war, civil rights, women rights, and against the Cold War, and the Nuclear race, among other things. This created a totally new youth culture during the 60s, giving place to the hippie wave and counter-culture movement that characterized the second part of the 20th century.
Answer: Four days after Austria-Hungary declared war on Serbia, Germany and Russia declare war against each other, France orders a general mobilization, and the first German army units cross into Luxembourg in preparation for the German invasion of France. During the next three days, Russia, France, Belgium, and Great Britain all lined up against Austria-Hungary and Germany, and the German army invaded Belgium. The “Great War” that ensued was one of unprecedented destruction and loss of life, resulting in the deaths of some 20 million soldiers and civilians.
On June 28, 1914, in an event that is widely regarded as sparking the outbreak of World War I, Archduke Franz Ferdinand, heir to the Austro-Hungarian empire, was shot to death with his wife by Bosnian Serb Gavrilo Princip in Sarajevo, Bosnia. Ferdinand had been inspecting his uncle’s imperial armed forces in Bosnia and Herzegovina, despite the threat of Serbian nationalists who wanted these Austro-Hungarian possessions to join newly independent Serbia. Austria-Hungary blamed the Serbian government for the attack and hoped to use the incident as justification for settling the problem of Slavic nationalism once and for all. However, as Russia supported Serbia, an Austria-Hungary declaration of war was delayed until its leaders received assurances from German leader Kaiser Wilhelm II that Germany would support their cause in the event of a Russian intervention.
On July 28, Austria-Hungary declared war on Serbia, and the tenuous peace between Europe’s great powers collapsed. On July 29, Austro-Hungarian forces began to shell the Serbian capital of Belgrade, and Russia, Serbia’s ally, ordered a troop mobilization against Austria-Hungary. France, allied with Russia, began to mobilize on August 1. France and Germany declared war against each other on August 3. After crossing through neutral Luxembourg, the German army invaded Belgium on the night of August 3-4, prompting Great Britain, Belgium’s ally, to declare war against Germany.
