Someone pls helpppp...~What is the authors main purpose in writing this article?Cite evidence from the text in your response.~.....HERE IS THE ARTICLE: ~Beginning in the 1950s, the United States and the Soviet Union (a socialist country that was made up of what are now 15 different countries and that existed from 1922 to 1991) had a very tense relationship known as the Cold War. Although the Cold War never did escalate from tension to real violence between the two countries, people in the United States worried that the Soviets might attack with a nuclear bomb. To prepare for such an event, elementary and high school students performed emergency drills at school, just as we might do fire or other safety drills today. The most common drill was called “Duck and Cover.”In a duck and cover drill, a student drops to the floor and gets under something, like a desk. Then they lie face-down, curl up, and cover the head and neck with a jacket, book, or even their hands. The goal of this drill was to protect against several dangerous side effects of a nuclear blast. The force of the explosion could create immense amounts of heat. It could also cause windows to shatter. Keeping one’s face on the floor could prevent burns and protect it from flying pieces of sharp glass.The United States government worked hard to teach as many people about the duck and cover drill as possible. In 1951 they also released a short video, also titled “Duck and Cover,” written for children in schools. This film featured a cartoon turtle named Bert, who ducked and covered whenever he saw a bright flash of light. Schools encouraged teachers to yell, “Drop!” in the middle of a lesson in order to see if students were prepared at any moment. Some cities even made small metal dog tags for children to wear, so that they could be identified in case a bomb killed them.The government also wanted to help adults know what to do in an emergency. They released informational pamphlets that explained the duck and cover position and other strategies to survive a nuclear attack. They sent trucks around the country to show the videos and pass out booklets of information. Stores and magazines advertised bomb shelters that people could buy to put in their backyards. Cities set up public “fallout centers” where people could go to run away from atomic radiation, and they also stored large amounts of food and installed emergency broadcast systems in public places. The federal government estimated that all these efforts would save 27 million people.Writers and scholars disagree about whether these programs were good or bad. Some say they promoted a healthy awareness of a real threat to the United States. Others say they gave people an unnecessary fear of crisis. School drills and other nuclear preparedness programs slowly went away in the 1960s, as U.S. leaders began to talk more openly with Soviet leaders.
