Final answer:
Margot organizes the articles separately because the audience for the sports page is different from the audience interested in politics.
Step-by-step explanation:
Margot organizes the newspaper articles by keeping the stories about the shutout baseball game and the new coach for the local college soccer team separate from stories about the upcoming political race because she knows that the audience for the sports page is different from the audience interested in politics. Different people have different interests, and Margot wants to make sure that each group of readers finds the articles they are most interested in.
