Final answer:
Mr. Barone is concerned about the author's lack of a career goal.
Step-by-step explanation:
In the excerpt from When I Was Puerto Rican, Mr. Barone, a guidance counselor, expresses concern about the author's lack of a career goal. This can be seen when the author says, 'When I told him I wanted to study literature, he shook his head and gave me that look, the one that said That's not possible.' Mr. Barone's concern is that the author does not have a clear plan for her future and he doubts her ability to achieve success without a concrete career goal.
