The right answer is: to communicate with enslaved people who are going to. Since it was not the right season for whippoorwills, Harriet could have used this sound. She was a fighter for the freedom of enslaved African Americans in the United States. In the showcase of the work, rescue missions were carried out in the slave network, using the antislavery network known as the underground railway. Later he helped John Brown after the capture of Harpers Ferry's arsenal, and after the war, he fought for suffering for women. In this case, and based on the expert, she could have told them that there was far more involved in this issue of running off slaves than signaling the runaways by imitating the call of a whippoorwill, or even a hoot owl, even more involved on it than just waiting for a clear night when the North star was visible.
