Questions: To whom it may concern: Subject: Information on Request We were sad to see you sent in a letter complaining about your defective car stereo system's warranty. Let me explain our policy regarding warranties. We normally honor warranties only from the date of purchase; however, because your situation is special, we will have to comply with your request. My supervisor has agreed to replace your unit for free. Choose the best revision for the salutation. Dear Sir: Mr. Enriquez: Dear Mr. Enriquez: What advice would you give to the author of the above message? Use a comma after the greeting to be more friendly. Save the good news until the end to build anticipation. Give readers the good news immediately.

The answer is "Dear Mr. Enriquez:" and "Give readers the good news immediately."

• Dear Sir: This is a formal salutation but lacks personalization. It is not the best choice when the recipient's name is known.
• Mr. Enriquez: This is informal and lacks the appropriate salutation prefix, making it less professional.
• Dear Mr. Enriquez: This is the most appropriate choice as it is both formal and personalized, addressing the recipient directly and respectfully.

• Use a comma after the greeting to be more friendly: While a comma can make the greeting seem less formal, it is not necessarily more friendly. The choice between a comma and a colon often depends on the level of formality desired.
• Save the good news until the end to build anticipation: This approach can be effective in some contexts, but in business communication, it is generally better to be direct and clear.
• Give readers the good news immediately: This is the best advice in this context. Providing the good news upfront helps to set a positive tone and ensures that the recipient understands the resolution quickly.
