Without direct access to the specific text of Corinne Segal's article "Why Journalism Has a Gender Problem," I can't provide the exact reasoning behind the inclusion of a question in the 12th paragraph. However, in general, authors use questions to engage readers, provoke thought, and guide the focus of the discussion. A question can introduce a new perspective or concern related to the topic at hand, encouraging readers to consider the implications or nuances of the gender issues in journalism. It may also serve to emphasize a key point or transition to another critical aspect of the narrative.
If you can provide the text or context of that specific paragraph, I can analyze it further for you.
