In the context of Caroline's scenario, which factor might significantly impede her ability to earn a reward?

A restricted range of options can significantly impede Caroline's ability to earn a reward because it limits her choices and opportunities for success. When individuals have a narrow selection of pathways or methods to achieve a desired outcome, they may feel constrained and unable to explore alternative strategies that could be more effective or suitable for their unique strengths. This limitation can lead to frustration and decreased motivation, as the potential for success becomes diminished.

In behavior analysis, providing a variety of options can help foster independence and allow individuals to find the most effective way to earn rewards. This flexibility can enhance their engagement and willingness to participate in tasks, ultimately improving their chances of success. Thus, having a broader range of options is typically associated with higher motivation and better performance.
