Effective messages ________.

A) convey abstract ideas
B) provide practical information
C) are usually voluminous
D) do not attempt to influence the reader

Effective messages provide practical information that is clear, concise, and relevant to the recipient. They should be easy to understand and should help the reader accomplish a task or make a decision. They should also be tailored to the specific audience and should consider their needs and interests. Messages that are too long, convoluted or attempt to convey abstract ideas without practical application are not effective. Additionally, many messages attempt to influence the reader in some way, whether it be to take action, change behavior or adopt a certain viewpoint. This is often a key goal of effective messaging.
