The correct answer is "Sweatt ruled that “separate but equal” graduate and professional schools were constitutional. Brown overturned that decision."
<em>"Sweatt vs Painter" </em>ruling was successful in challenging the "separate but equal" doctrine of racial segregation established by previous case "Plessy vs Fergusson". Sweatt ultimately won the case when the Supreme Court concluded that Thurgood Marshall School of Law failed to qualify for being a "separate but equal" educational institution, as it lacked the sufficient facilities to become one.
<em>"Brown vs Board of Education"</em> ruling effectively overturned the ruling of the <em>"Plessy vs Fergusson case"</em>, when the Supreme Court indicated that state laws that permitted separate public schools were unconstitutional.

Explanation:
Many of the European powers had entered into alliances requiring them to defend each other.
The systems of alliances and military plans which were put in place before World War I presupposed a major war between the countries which were tied together with alliances. Because the Triple Entente had Britain, France and Russia as allies, Germany thought if a war began it would need to fight on two fronts -- west and east. So German Field Marshall Alfred von Schlieffen drew up war plans that said attack France first, quickly, and then hold that territory while deploying forces to contend with Russia in the east.
So then here's how it happened. When an Austrian prince and his wife were assassinated in Serbia, the Austrian Empire threatened the nation of Serbia with retaliatory action (even though the assassination was carried out by a terrorist group, not the Serbian government). Russia responded to Austria's threat, because Russia was bound to protect its Slavic ally, Serbia. Germany responded to the mobilization of Russian troops, and when Germany declared war on Russia in 1914, they implemented the Schlieffen Plan and went on attack vs. France. That pulled France and Britain into the war immediately as well, and the war spread and became a global conflict.
In the late 20th century, immigrants who moved from former colonies to their former imperial nations tended to settle in metropoles where jobs were available. The correct option among all the options that are given in the question is the second option. People needed money to survive. I hope the answer helps.
