Last question today. Without rephrasing (written exactly as they are presented below), does the punctuation work in each of these? The questions 'Who?', 'What?', 'When?', 'Where?', 'How?' and 'Why?' remain unanswered. The investigator's 'Did you do it?', 'How did you do it?' and 'Why did you do it?' questions unnerved Ralph. His 'a's look like '8's. I'm tired of his 'thank-you's, 'I love you's and 'maybe's. John said, "He used too many 'as's and 'is's in that last paragraph."
