Final answer:
Jack is using paraphrasing to clarify Wendi's suggestion about changing the inventory report format, which ensures clear and accurate communication.
Step-by-step explanation:
Jack is using the communication technique called paraphrasing to clarify Wendi's suggestion. Paraphrasing involves restating someone else's words in your own words, while keeping the original meaning intact. It's often used to make the information clearer or to present it in a way that is more consistent with the speaker's own style.
In this scenario, Jack is attempting to confirm his understanding of Wendi's idea by rephrasing what she has suggested about changing the inventory report format, demonstrating active engagement in the conversation rather than merely repeating her words as in quoting, or not responding at all, which would be considered passive listening. Paraphrasing helps to ensure that communication is accurate and that both parties have a mutual understanding of the topic at hand.
