Final answer:
The common idea among residents of relocation camps was the desire for freedom and equality, as they faced forced abandonment of homes, bleak conditions, and family separations, yet strove for community and cultural preservation.
Step-by-step explanation:
The residents of the relocation camp, many of whom were U.S. citizens, had several ideas in common. However, based on the provided information that highlights their experiences during internment, it's clear that the desire for freedom and equality is the common thread. The internees were forced to abandon their homes and businesses, and conditions at the camps were bleak, with families being separated and individuals undergoing investigation and interrogation. Despite this, many showed loyalty to the United States, some volunteering and later enlisting in the army. On the other hand, others felt betrayed and denounced the United States. Despite the difficult circumstances, they also banded together to improve their quality of life within the camps. They created schools, engaged in cultural activities, and participated in sports, with a particular emphasis on baseball, to maintain a semblance of community and culture.
