One important goal of a buffer is to

A) delay stating the bad news.
B) establish common ground with your reader.
C) make your reader wonder what the message is about.
D) divert the reader's attention to a more pleasant subject.
E) offer alternative ways of solving a problem.

A buffer is used to establish a connection with the reader and create a positive tone before delivering the main message. It helps to establish common ground and create a receptive mindset for the main message. Delaying bad news, diverting the reader's attention or offering alternative solutions are not the primary goals of a buffer.
