- Read the excerpt from Outcasts United.Somehow, Luma would have to find a way to get all these kids to play as a unit. "It was about trying to figure out what they have in common," she said.While Luma was trying to find a way to get the kids to play together, she was also getting to know their parents, most of whom were single mothers. She quickly discovered that these women needed help—mostly in understanding paperwork. With her Arabic and French, Luma was able to translate documents and answer some of their questions. She made appointments with doctors and social workers. Luma gave her cell phone number to her players and their families, and soon they were calling with requests for help. Teachers learned to call Luma when her players' parents couldn't be found or were at work. The families showed their gratitude by offering Luma tea and inviting her to dinner. Luma felt needed, and couldn't help but notice how much better this kind of work felt than running Ashton's. Based on Luma's actions, which statement best describes the theme in this excerpt?
