The creation of Title IX in college sports has had a lasting impact on women’s sports in the United States. Title IX is a federal law that states that women cannot be discriminated against in athletics at schools, colleges, or universities that receive federal funding. It has allowed girls and young women to pursue sports and go on to compete on the world stage, especially in professional soccer. The World Cup soccer competition in 2016 was a significant moment, as the United States women’s team advanced to win the title. While male professional athletes still outrank women in terms of salary, women are gaining prominence. Many women play on professional teams and have sponsorships with major companies. One of the most significant places that Title IX has had an impact on is high school sports. Which word would best replace the bolded word, significant, in the fourth sentence?
