Answer: D. Use PowerPoint slides for each separate concept.
Step-by-step explanation:
These associates are completely new which means that they have to first be introduced to the required opening and closing call sequences. Several methods would therefore be inappropriate.
Complete roleplay for instance, would be bad for the situation as the associates would have no sequence to fall back on seeing as they are new. A quiz would also not work because it needs to be based on material learnt and individual written scenarios would be wrong as well because the goal is to teach them the company's required sequence not their own.
The best way would be to simply show them these sequences in a PowerPoint presentation.
