The reason why this sentence should be eliminated is that it does not contribute to the main idea of the paragraph. The paragraph discusses the differences between girls' and boys' sports. It argues that equal funding is necessary, that many girls are involved in sports, that both girls and boys can benefit from sports and that federal law prohibits gender discrimination. However, sentence 3 does not address the topic of gender. Instead, it discusses the differences between individual and team sports. Therefore, the paragraph would make more sense and flow better if this sentence was removed.
