The correct answer would be:
The broader implications of an idea would be discussed before the reader understands what the idea is.
Explanation: Reversing the order of paragraphs 3 and 4 would mean that the article discusses the broader implications of the lack of diversity in journalism before presenting the specific statistics about women and racial minorities in the industry. This change could lead to confusion for readers because they would be introduced to the significance or implications of the issue without first having a clear understanding of the actual data that highlights the problem. Thus, the context and specifics of the statistics would be necessary for readers to fully grasp the implications being discussed.
