If you reversed the order of paragraphs 3 and 4 in the article, the correct response would be:
The extent of the problem would be lost on readers because they would not receive all the data.
This is because paragraph 3 provides specific statistics about women in journalism, while paragraph 4 focuses on racial minorities and their representation in the industry. By reversing them, the specific details and context regarding women's representation would not lead into the discussion of racial minorities effectively, potentially causing confusion or a lack of understanding about the full scope of the diversity problem in journalism.
