Final answer:
No, "We'll never be able to get it to you by then" is not a positive response, it is a negative response.
Step-by-step explanation:
No, "We'll never be able to get it to you by then" is not a positive response, it is a negative response. The word "never" indicates that the action of getting it to you by then is not possible. A positive response would be something like "Yes, we can definitely get it to you by then."
