I'd like to ask the writer (of "Risks are part of being young" in today's 24H Vancouver), 'where is the missing closing quotation mark?' Also, why did you put the question mark inside the single closing quotation mark? In fact, sticking a single closing quotation mark immediately in front of the question mark would solve both errors.
