In the following question, an incomplete statement

Solution

The phrase "implemented overnight" implies that the policy was introduced suddenly, likely without proper communication or preparation. Hence, the result would reasonably be confusion or unawareness among employees. (1) prepared and confident to follow it – contradicts the idea of a sudden, overnight implementation (2) confused and unaware of what changes had occurred – aligns well with the context (3) well-trained to manage the transitions – unlikely if the policy came unexpectedly (4) eager to implement more policies – irrelevant to the idea of confusion or sudden change
