Answer: D "The following year, Little Rock School District officials under the command of Faubus closed the schools to prevent integration. But in 1959, the schools were open again. Both black and white children were in attendance." (Paragraph 7)
Step-by-step explanation:
The relevant text is called ''Showdown in Little Rock'' and it talks about the events of September 1957 when 9 Black American children tried to attend a previously all-white school which had now been desegregated thanks to a Supreme Court ruling. This led to a backlash from pro-segregationists.
Part A asks about the central idea of the text and this answer is that, ''the Little Rock Nine helped break racial barriers in American education despite great opposition.''
The supporting text in Part B is that even though the school was closed to prevent integration, its reopening saw integration in full effect and this contributed greatly to the removal of racial barriers in America's education system.
