Dr. woolston is interested in studying teenagers social lives and the challenges they face. dr. woolston should consult with his colleague who would argue that the main difficulty teenagers face is forming a sense of piaget; identity piaget; morality erikson; morality erikson; identity

The correct answers are Erikson; identity - so the final option here.
Piaget mostly studied the behavior or children, whereas Erikson focused on teenagers more. Also, it is known that teenagers have many issues with figuring out who they really are and they are searching for "themselves" because they don't have a sense of identity yet.
