• Requests, suggestions, and commands are often phrased as questions out of politeness.
• Use a period to end this kind of sentence if you expect your reader to respond by acting rather than by giving you a yes-or-no answer.
• Use a period only when you are sure that your reader is not likely to consider your request presumptuous.

1. Will you please call us at once if we can be of further help.
2. Would you please send all bills to my bank for payment while I’m out of the country.
3. May I suggest that you refer to computer criminals who break into other people’s computers as crackers, not hackers.
4.

 If you are asking a favor or making a request that your reader may be unable or unwilling to grant, use a question mark at the end of the sentence.
 The question mark offers your reader a chance to say no to your request and helps to preserve the politeness of the situation.

1. May I ask a favor of you?
2. Will you be able to have someone help me on the Woonsocket project?
3. Will you please handle the production reports for me while I’m away?

If you are not sure whether to use a question mark or a period, reword the sentence so that it is clearly a question or a statement; then punctuate accordingly.
Would you be willing to handle the production reports for me while I’m away?
Reworded sentence:
I would appreciate your handling the production reports for me while I’m away.

 When you are addressing a request to someone who reports to you , you expect that person to comply. Therefore, a period can properly be used.

 A question mark establishes a nicer tone and often gets better results.

4. We know what needs to be done; the question is how to pay for it.
5. I wonder who defined intuition as the knowledge that your salary won’t cover the cost of your children’s education.

 Do not add a period if the numbers or letters are enclosed in parentheses .
