Final answer:
Grandma India advised Melba to have faith and maintain her moral ground, inspired by the story of Job. She helped her focus on completing the school year as part of the Little Rock Nine, and Melba recited the 23rd Psalm for strength.
Step-by-step explanation:
The advice that Grandma India gave Melba to help her stay strong through the struggle was to have faith in God’s plan and to maintain her moral ground, no matter the challenges she faced. This advice was inspired by Grandma India's deep-seated religious beliefs and her interpretation of the biblical story of Job, who showed immense patience and faith in the face of adversities. Grandma India also helped Melba focus on a project, which was to stay the course and complete the school year despite the discrimination and hostility she was enduring as one of the Little Rock Nine integrating Central High School. To keep her resolve, Melba would recite the 23rd Psalm, which helped her find inner strength and solace amid the turmoil.
