A World War Begins

Explanation
An arms race refers to a competitive situation between countries where they strive to develop and acquire more powerful and advanced weapons. This competition is driven by a desire to gain a military advantage over other nations and maintain national security. It involves a continuous cycle of developing new technologies, increasing military capabilities, and expanding defense budgets. The term "arms race" is commonly associated with the Cold War era, where the United States and the Soviet Union engaged in a fierce rivalry to outdo each other in terms of military strength.

Explanation
The statement is true because a terrorist is indeed a person who carries out violent acts with the intention of achieving political goals. Terrorism is often used as a means to create fear, intimidate a population, or influence government policies. The actions of terrorists are driven by ideological, religious, or political motivations, and they often target civilians or non-combatants. The use of violence distinguishes terrorists from other political actors, such as activists or protesters, who typically employ non-violent means to express their grievances or advocate for change.

Explanation
A stalemate refers to a situation in a game or conflict where neither party is able to make a move that results in a win or a loss. It is a deadlock where both sides are equally matched and unable to make any progress. In this scenario, there is a standstill and no clear outcome can be achieved.

Explanation
The correct answer is "all of the above." This means that extreme nationalism, imperialism, and alliances were all causes of World War I. Extreme nationalism refers to the intense pride and loyalty to one's own nation, which can lead to conflicts and tensions between countries. Imperialism involves the expansion of a country's power and influence over other territories, often resulting in competition and rivalries between nations. Alliances formed between different countries can create a complex web of obligations and commitments, which can escalate conflicts and draw multiple nations into a war. Therefore, all of these factors contributed to the outbreak of World War I.

Explanation
The assassination of King Louie IV was not one of the causes of World War I. The war was primarily caused by a complex web of political alliances, territorial disputes, and the desire for power and dominance among European nations. The assassination of Archduke Franz Ferdinand of Austria-Hungary in 1914 is often cited as the event that triggered the war, as it led to a series of diplomatic and military actions that eventually escalated into a global conflict. King Louie IV's assassination, on the other hand, did not have a direct impact on the outbreak of World War I.

Explanation
The Allied Powers were a group of countries that fought against the Central Powers during World War I. Switzerland was a neutral country during the war and did not align with either side. France, England, and Belgium were all part of the Allied Powers and played significant roles in the conflict. France and England were major military powers, while Belgium was invaded by Germany, leading to their involvement in the war.

Explanation
Germany, Austria-Hungary, and the Ottoman Empire were all Central Powers during World War I. These countries formed an alliance known as the Central Powers, which opposed the Allied Powers. They fought against countries such as France, Britain, and Russia during the war. Spain, on the other hand, was not part of the Central Powers and remained neutral during World War I.

Explanation
Bulgaria was neutral during World War I. While the Netherlands, Norway, and Luxembourg were also neutral during the war, Bulgaria's neutrality is specifically mentioned in the question. This suggests that the question is asking for a specific response regarding Bulgaria's status during the war.
