The central idea of the article is best captured by the response: "The first three paragraphs lead up to it."
This choice is correct because the article discusses various factors contributing to the disparity in leadership and representation of women in industries such as journalism and tech. The initial paragraphs analyze specific barriers such as the types of news beats that are mainly assigned to men and the cultural attitudes that disadvantage women in leadership roles, ultimately leading to a broader understanding of the central issue at hand. This progression through the text builds context and supports the central idea rather than stating it directly at the beginning or end.
