Answer:
The correct answer is the second one: <em>President Eisenhower sent federal troops to protect the students</em>.
Explanation:
The first statement doesn't relate to the question and the last statement refers to an event before the integration in the High School in Little Rock.
In 1954 the Supreme Court had ruled in Brown v. Board of Education case that segregation in public schools was unconstitutional.
So in 1957, the black movement decided to test the decision by registering nine black students in the Central High School in Little Rock, Arkansas. Governor Faubus tried to stop the group from studying there by calling the Arkansas National Guard to prevent their entrance to the school.
A few days later President Eisenhower sent in federal agents and troops to escort the students into the school.
The black students were recruited by a member of the local NAACP (National Association for the Advancement of Colored People) and received counseling sessions to understand and to prepare for the beginning of the school year and to know how to act on possible hostile situations inside the school.
Traversing as they do all of Eurasia, the Silk Roads encompassed almost every climate and vegetation zone and crossed every kind of terrain. This sketch of Silk Road geography has the modest aim of introducing a few of the important features of Eurasian physical geography which help us to understand patterns of human habitation and interaction across that vast expanse. There are always regional variations which deserve more detailed treatment. Before the advent of modern technology, geography and ecological zones were critical determinants of where and how people lived, moved and interacted. Boundaries such as we know them, delineated by modern states, did not exist, but boundaries there were, either natural or manmade, and in both cases they turn out to have been quite permeable.
The reason the United States supported the creation of the United Nations was to (3) maintain international peace.
