Answer:
it's a way of testing your interpretation
It strengthens the concept in one mind
Step-by-step explanation:
Paraphrasing uses specific terms to recreate something. But paraphrasing might be a valuable listening device because
(1) it's a way of testing your interpretation (the individual who initially told you confirms your interpretation and can verify it's correct or ask you whether it's wrong).
(2) It strengthens the concept in one mind, because in attempt to paraphrase it, one should have to call on their own understanding of what they just hear.
