Will you let me hear from you as soon as possible -- I know it will be a sacrifice but times are still bad and likely to be, so by settling down you can help me and Blanche and gain in the end.
True or False - This is a request to communicate the response verbally as soon as possible, and, hence, a request if Frank and Caro decide to accept the offer to communicate a promissory accept as soon as possible.
