Question

explain in simpler terms Acceptance is the unambiguous agreement to all the terms of the offer. It must mirror the offer exactly; any variation constitutes a counteroffer rather than acceptance. Acceptance must be communicated to the offeror, and silence generally does not amount to acceptance .

Acceptance means clearly agreeing to everything that was proposed in an offer. To accept an offer, you need to say "yes" in the exact same way it was given; if you change anything, it's not an acceptance but a new proposal (called a counteroffer). Also, you have to let the person who made the offer know that you've accepted it. Just staying quiet does not count as acceptance.
