Final answer:
The director of a summer camp for chronically ill children is most likely to be an expressive leader due to the focus on creating a nurturing environment and communicating effectively with children with special needs.

Looking at the options provided, while each role may involve aspects of expressive leadership, the director of a summer camp for chronically ill children is more likely to be an expressive leader as their primary responsibility is likely to be creating a supportive, nurturing environment which is essential to the campers’ experience. This requires emotional intelligence, empathy, and the ability to communicate effectively with children who have special needs.
The sales manager of a fast-growing cosmetics company is likely to focus more on sales targets and strategies, which are characteristics more of an instrumental leader. A high school teacher at a reform school does need to build relationships, but is also focused on discipline and education. A manager at a fast-food restaurant focuses on efficiency and ensuring tasks are completed quickly, which is not typically the domain of an expressive leader.
