In juanita's community, girls are not expected to enjoy or excel at mathematics. juanita's algebra grades drop; by the time she is a high school junior, she is enrolled only in consumer mathematics courses. which concept does juanita's example best illustrate?

Self-fulfilling prophecy is the correct answer.

In Psychology, self-fulfilling prophecy is a prediction that directly or indirectly influences the outcome to become true. They are not facts, but mere guesses  that were based on the best information available. In Juanita's cases, since no girls are expected to succeed at Mathematics in her community, she doesn't believe she can excel at Math either which leads to her auto-sabotage.
