Editing for End Punctuation
If all or almost all of your sentences end with periods, see if some of them might be phrased more effectively as questions or exclamations. (41a–c)
Check to be sure you use question marks appropriately. (41b)
If you use exclamation points, consider whether each is justified. Does the sentence call for extra emphasis? If in doubt, use a period instead. (41c)
