Read the quote from the supreme court's decision in brown v. board of education. we conclude that, in the field of public education, the doctrine of "separate but equal" has no place. separate educational facilities are inherently unequal. compared with the decision in plessy v. ferguson, this opinion

The correct answre is: "Brown v. Board of Education overturned in 1954 the former decision reached in 1896 in Plessy v. Ferguson".

Brown v. Board of Education was a case dicussed by the US Supreme Court, which  led to the enactment of a landmark decision  in 1954.  

The case was about the constitutionality of the "separate but equal" principle that was accepted in a former decision enacted by the US Supreme Court in 1896 in the Plessy v. Ferguson case. Such decision allowed the proliferation of segregated schools under the belief that, if facilities were equal in quality, such education system was not violating the equality of rights provision that had been guaranteed for all US citizens by the Reconstruction Amendments to the US Constitution.  

Brown v. Board of Education overturned the abovementioned previous Supreme Court decision and declared segregation unconstitutional, claming that, in practice, it actually deprived black students. The court published a deadline and all public schools nationwide had to abolish such practice and to adopt racial integration.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
