Which events added to Americans’ fear of attack by the Soviet Union? (choose all that apply) Group of answer choices the 1956 Olympic Games the U-2 incident first test of a Soviet atomic bomb the Sputnik launch
The correct answers are B) the U-2 incident, C) the first test of a Soviet atomic bomb, C) the Sputnik launch.
The events that added to Americans’ fear of attack by the Soviet Union were the U-2 incident, the first test of a Soviet atomic bomb, and the Sputnik launch.
Those wear the tense years of the Cold War in which the Soviet Union competed in the arms race and later in the space race. The world lived tense moments that were at its peak during the Cuban missiles crisis of 1962, where the world was on the brink of another war.
After the United States knew about the first test of a Soviet atomic bomb, the government set the alarms. Then, when the USSR sent the first satellite -the Sputnik- into space, the federal government knew that the risk of an attack was more because the Soviet Union could steal critical information about the US security and intelligence. After the U-2 incident, there was no doubt that an attack was a real option.

What system in society is responsible for maintaining order and ensuring security of its citizens? the Monarchy the Government the IRS the Culture
Hey there! I'm happy to help!
The IRS collect your taxes; they don't have anything to do with security.
The culture is the traditions and common habits of the people. Culture is not a government organization so it does not really maintain order or ensure security.
The monarchy is basically the royalty or nobility. They rule the country but usually the king himself does not ensure security for his citizens.
The Government is what protects people's rights, ensures their security, and maintains order. There are many government systems set up to secure all of these rights.
I hope that this helps! Have a wonderful day! :D

What happened in the First Opium War
There were two wars that consisted of the Opium Wars. They are mostly fought between China and Great Britain in the 1800s.
Before the First Opium War, Great Britain was selling opium to China, which is a highly addictive drug. They were making a lot of money off of China, as many people started to get addicted. Over time, China started to get fed up with this. They were sick of seeing their people get more and more addicted to opium and wanted to put a stop to it. They tried to ask Great Britain to stop selling the Chinese people opium, but they continued to do so. This ended up breaking out in a war.
During the First Opium War, Great Britain easily moved into China with its navy. They were much more equipped and had newer machines, which China did not. They easily destroyed the Chinese Naval units and continued to move inwards. They ended up opening the opium trade in China, which China had previously closed, and now Great Britain had full control over Chinas trade. They took control over cities, people, and held an obvious lead.
China knew that they were not going to come back from this or win, they needed to make a negotiation. The negotiation is called the Treaty of Nanking, this made China give Great Britain a very large sum of money, access to Hong Kong, and opened up trade with the countries.

En tiempos normales se nos habla de la abstracción de la no-vida y ahora en esta epidemia se nos habla de la vida y la muerte, que relación tiene esta frase con el capitalismo?
La respuesta correcta para esta pregunta abierta es la siguiente.
La relación que tiene esta frase con el capitalismo es que dentro de este sistema económico, todo es un negocio. Si un emprendimiento no resulta en ganancia, simplemente no se invierte en ello.
En estos momentos de pandemia, los grandes capitales e inversionistas podrían aportar la suma de dinero que se necesita para el pronto desarrollo de una vacuna contra el virus. Sin embargo, y hasta el día de hoy, esa ambición de generar dinero no ha convencido a los hombres del poder para poder invertir en salud pública. Simplemente no es negocio y no es lo suyo.
Anteriormente, científicos Europeos ya habían considerado la posibilidad de desarrollar este tipo de vacunas contra varios tipos de gripa. Para ello, necesitaban subvenciones o inversionistas para realizar sus investigaciones. Nunca recibieron respuesta.

American history What gave rise to the slave trade?
Answer:
La historia de la esclavitud en el mundo antiguo está estrechamente vinculada a la guerra. ... Así, entre algunos grupos africanos, las mujeres y los niños eran entregados como rehenes de deudas u otras obligaciones hasta su pago; y, si el pago no se realizaba, los rehenes pasaban a ser considerados esclavos.
Explanation:
La historia de la esclavitud en el mundo antiguo está estrechamente vinculada a la guerra. ... Así, entre algunos grupos africanos, las mujeres y los niños eran entregados como rehenes de deudas u otras obligaciones hasta su pago; y, si el pago no se realizaba, los rehenes pasaban a ser considerados esclavos.
The slave trade arose as there was a shortage of man power in the United States as well as cost effectiveness.
The US settlers typically hired new settlers from the Old World in the beginning to work for them, but wages had to be fair and they were allowed to leave after a predetermined time period.
The US settlers then moved to using Native Americans to help work for them, but they developed little to no protection against European diseases, leading to a under population and a smaller work force to be used.
As the cotton & tobacco farms in the south required large amounts of work hands, the Americans turned towards using African slaves to help. With profits rolling in and greater production from having more hands on the deck, the United States continued to purchase slaves, primarily in the south. This led to what is known as a slave trade triangle, as the Americans bought slaves from Africa, in turn Africa received finished goods from Europe, and Europe received raw material from the Americas. With profit comes more investment into the venture, and with more investment means more people needed to work on the ever growing plantations to create more profit. This is what gave rise to the slave trade, the want for profit, and for money.

How did the end of the Vietnam War mark a difference in US foreign policy? A. The US had never lost a war before, making war a less favorable option B. The US required an attack on US soil first before beginning a war C. The US would not get involved in any foreign wars after it D. The US would begin new wars in Southeast Asia to prove its strength
Answer:
B
Explanation:
The US had never lost a war before, making war a less favorable option: the end of the Vietnam War marked a difference in US foreign policy. Thus, option A is the correct option.
The end of the Vietnam War marked a difference in US foreign policy in that the United States became more hesitant to engage in large-scale military interventions. Option A is the most accurate choice among the given options. The Vietnam War was a costly and divisive conflict for the United States, resulting in significant loss of life and resources without achieving the desired outcomes.
The war had a profound impact on public opinion and eroded the American people's trust in the government's decision-making regarding military engagements. As a result, there was a shift towards a more cautious approach to future military interventions, with a greater emphasis on diplomatic solutions and a reluctance to commit to protracted wars without clear objectives or popular support.

ASAP I need help plss
Answer:
Due to pressure of the government.
Explanation:
Author mean from the statement was that the government will not allow the press to make their opinions freely because they had a full control on the press and allow those statement which favors the government. Before the war, one group of media is in favor of south while the other is in favor of north so both groups support their respective states but after the war, the media who support the south will not be allowed to speak freely against the government of north due to their control over the whole country. So that's why the author made that statement.

Answer:
One historical example was Tokugawa shogunate (Edo shogunate) was an autocratic Japan under the rule of Tokugawa Ieyasu.
One fictional example is the Empire of Star Wars, under the rule of the Sith Emperor Palpatine.

Using his cunning and leadership ability, he controlled the entire region of the republic turned empire, leading to his ultimate control of the known galaxy.
