If you reversed the order of paragraphs 3 and 4, the broader implications of an idea would be discussed before the reader understands what the idea is.
This is because paragraph 3 provides specific statistical data related to women in journalism, while paragraph 4 likely discusses the implications or significance of these statistics. By reversing them, readers could be confronted with broader implications without first having a foundational understanding of the specific statistics that illustrate the extent of the gender problem in the journalism industry. Therefore, the shift in order could lead to confusion or a lack of clarity for the reader regarding the significance of the statistics provided.
