Final answer:
A toy commercial is the least likely source to indirectly teach about prejudice.
Step-by-step explanation:
The source that is least likely to teach indirectly about prejudice is a toy commercial.
Prejudice is often taught and learned through various forms, such as direct instruction, observation, and socialization. Movies, books, and even a desire to impress others can contribute to the development of prejudices. However, a toy commercial is primarily focused on selling a product and may not contain content that addresses or teaches about prejudice indirectly.
For example, a toy commercial may showcase children from diverse backgrounds playing together, but it may not explicitly or indirectly address the topic of prejudice, stereotypes, or discrimination.
