Answer:
to protect her from harm
Explanation:
Ruby Bridges was the first black child to study at a school composed only of white students, during the period when racial segregation was ended and prohibited. However, several white citizens disapproved of this and formed a large crowd to prevent Bridges from reaching the school, or even from entering the school and attending classes. For this notice, it was necessary for her to be escorted by US marshals, who would protect her from the crowd, who were trying to attack her.
