<p>If I wanted to say, for example... </p>
<p>They asked questions like "Who did it?" "When did it happen?" "When was it?"...</p>
<p>do I need a comma after like? a colon? something else? how do i list questions in quotes?</p>
<p>I've seen a comma put outside the quotation marks in cases like this. A semicolon might suffice.</p>
