I believe it would be the shared experiences dilute traditional cultures. It can’t be the 2nd or 3rd answer because those are positives and it is asking for a negative effect, but I don’t think it is the 4th answer either because I don’t believe that being able to experience the same things would eliminate a culture entirely. Yes it could dilute it because we’d be almost overcoming cultural barriers by connecting through shared experiences throughout the world, but the effects of shared experiences don’t translate to things like genocides or systemic discrimination in an attempt to eliminate a culture.
Plessy v Ferguson (1896) was the earlier ruling overturned by Brown v. Board of Education (1954).
Brown v. Board of Education of Topeka, decided by the US Supreme Court in 1954, extended civil liberties to all Americans in regard to access to education. Until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students. The older Supreme Court decision, Plessy v. Ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality. In the case of Brown v. Board of Education, that standard was challenged and defeated. Segregation was shown to create inequality, and the Supreme Court unanimously ruled segregation to be unconstitutional.
The correct answer is B. India started the non-alignment movement.
Explanation
When the Second World War ended the world was divided into two socio-political blocs, on one side there was communism and on the other side capitalism. The United States was the main Capitalist country, while the Soviet Union was the main Communist country. This ideological difference gave rise to the Cold War from the middle of the 20th century. During this time, these countries tried to impose their ideologies on the other countries of the world to establish superiority. This generated wars like Korea war or Vietnam war. On the other hand, the non-alignment movement was a group of countries that rejected this world political polarization and decided to declare themselves in a neutral position rejecting communism and capitalism. So the correct answer is B. India started the non-alignment movement.
