On pages 223 and 224, Carlotta mentions several historical events including the March on Washington, where Dr. King gave his “I Have a Dream” speech; the bombing of the 16th Street Church in Birmingham, Alabama; and the assassination of President Kennedy. What are Carlotta's reactions to these events? What might account for Carlotta's different reactions to them?

Carlotta seems to be removed from the events. She describes her reaction to the March  on Washington like this: “I had no burning desire to participate in a march that seemed  to me then purely symbolic,” but then she felt how powerful it was when she saw the  thousands of people on television. However, when Carlotta heard about the 16th Street  Church bombing and President Kennedy’s assassination, she was horrified.  

It seems like her reaction to the March on Washington reflected her experience—a  march by itself didn’t seem to mean much after her time at Central High School where  she faced so much discrimination. Upon hearing the news of the 16th Street Church  bombing, however, she said, “I knew that the same fate so easily could have been  mine.” She identified with the victims in that case. Similarly, President Kennedy’s  assassination made her reflect on her experiences, saying “his life extinguished by the  same kind of hatred that had been so rampant in Little Rock. I wondered how—and  sometimes why—I survived.”

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.
