Optimizing a Chatbot for Complex Queries

A developer is using a large language model to solve multi-step mathematical word problems. They observe that the model often provides an incorrect final answer, even when the initial setup seems correct. The developer's current prompt simply states the word problem and asks for the final numerical answer. Which of the following prompt refinement strategies is most likely to improve the model's accuracy on these types of tasks?

Match each prompt engineering problem scenario with the most appropriate solution approach.
