Final answer:
Segora is demonstrating characteristics of identity foreclosure because she is pursuing a career in teaching based on family expectations rather than exploring her individual interests.
Step-by-step explanation:
When 18-year-old Segora, who comes from a family of teachers, says she is going to school to become a teacher because it is sort of expected in her family, she demonstrates characteristics of identity foreclosure. Identity foreclosure is a term from the theory of identity formation that refers to a person committing to an identity without exploring other options. In this case, Segora seems to be following a path set out by family tradition rather than exploring her own interests or considering other career possibilities.
