Answer:
Kim could benefit by "improving her questioning skills".
Step-by-step explanation:
Kim should learn to ask relevant questions and at the right time during a call, to stay in control.
For such customers that seem to talk about unimportant things on calls, Kim could ask close-ended questions that require "yes" or "no" or short answers, and follow up the answers with similar questions.
She should avoid open ended questions that allow room for the customer to provide lengthy answers.
This will help her maintain control of her sales calls and get her message across to the customer.
