Answer: A clear statement of the problem
Step-by-step explanation:
The opening of a direct claim message should clearly state the problem that you would like to be addressed by the receiver and would set the tone for the rest of the message.
Claim messages are formal messages and as such, should be clear and concise so that the message is communicated effectively and there is a lesser chance of the message being misread. This is why the message should be clearly stated, so that the receiver understands it and responds in kind.
