Explanation: The conflict in the paragraph is that a sweater is given to her by Mrs. Price, but the sweater isn't actually hers. Rachel doesn't know how to tell the teacher this. This tells me that Rachel is a shy person or a worried one. She just doesn't know how to use her voice. Rachel wishes she was older so she could handle the situation better.
Rachel experiences a self vs self conflict in which she wishes that she was older, therefor holding more knowledge and maturity, and being able to face difficult situations more easily. This tells us that Rachel might be easily intimidated or scared, as well as wistful, and that she may have an idealization of becoming an adult.
