Final answer:
Esperanza's current challenges could involve the need for sustainable funding against larger arts organizations competition, and addressing educational inequalities faced by disadvantaged communities.
Step-by-step explanation:
Esperanza's biggest challenge right now seems to be related to the themes of identity and social struggle. The context provided suggests that Esperanza might be grappling with the need for sustainable funding and competition against larger arts organizations, as well as dealing with the challenges faced by communities in poverty and educational inequalities. For example, a community with a predominant presence of the Puerto Rican flag faces the struggle for sustainable funding, and a school consisting mostly of African American and Hispanic students from poor families is trying to overcome the barrier of achieving educational performance on par with their more affluent peers. These challenges reflect the broader social issues that Esperanza might be facing in her current situation.
