Answer:
indirect characterization
Explanation:
indirect characterization is when a character is described or characterized indirectly. this means the author describes a character with details; what the character says or does.
it does not simply say "____ is ____ (description like mad, annoying, sad, pretty).
in this example, Gloria "withdraws into a shell where she feels safe and hidden." what is this saying about her? she is shy and insecure. the author does NOT say "Gloria is shy." Or "Gloria is insecure."
