Final answer:
A sales associate should continue the conversation by discussing the features and benefits of each coat, helping the student decide based on her personal style and needs.
Step-by-step explanation:
The best way for the sales associate to continue the conversation with a student who has narrowed down her choices to two coats would be by providing personalized attention and guidance to help her make the final decision.
Discussing the features, benefits, and suitability of each coat in relation to the student's personal style, needs, and preferences can ensure a satisfactory purchase decision.
For example, the associate might ask questions like 'Which of the two coats do you feel more comfortable in?' or 'Is there a particular occasion you're shopping for?' This approach not only helps the customer but creates a positive shopping experience.
