I believe it’s Cascading Style Sheets
this is the answer 1. Sputnik 1 was the first Soviet man-made satellite to orbit the Earth. Sputnik was the first major event that would set off what we know today as the Space Race. It remain in low earth orbit, but it was the first successful launch and provided some feedback to various space agencies. 2. The U.S. supported the democratic South Korea against a Communist backed North Korea. While they did attempt to take the whole peninsula, when things drew more towards a draw, the US opted to maintain a defensive position and keep the North where it was. 3. The GI Bill led to a large housing boom and the creation of the first suburban housing developments. It started the first "cookie cutter" form of the suburbs that are so common place today. 4. American response to the launch of Sputnik was the fear that we were some how inferior to the Soviets. This led to a mass push of science, technology, and missiles education in public schools. 5. A politician accused of "McCarthyism" would make sweeping accusations with little to no evidence. They would hope that the large accusations and scene around being accused would be enough to cause the opposition to fold. 6. Segregation undercut the US moral high ground during the Cold War. How could the US claim the Soviets were not morally better and spout about how wrong it was to oppress people when the US was holding back and oppressing people themselves. 7. The Truman doctrine was a shift from the isolationist policy to stay out of others affairs. Truman spoke to Congress how it should be their duty to protect free people of the world from Communism and the hostile threat that it imposed. 8. Most Southern schools refused to integrate until a court order in 1977. Some places brought out the National Guard, most notably Little Rock, Arkansas. Many simply refused to go along with order. 9. The Marshall Plan was designed to contain Communism by giving money to Western European countries after World War II. This would better help them to recover and stave off the Communist threat. 10. The US's containment policy was solely designed to contain the Communist threat by increasing their presence around the world and supporting democracies, both militarily and economically
I believe the last choice is correct
