Let's generate an interactive story inspiration builder for my 10 year-old students. There are 4 clickable story components displayed in 4 boxes. When a user clicks the boxes,  a random subject for each component is provided. The components are "genre," "setting," "main character," and "conflict." The activity should be pre-loaded with 5-10 choices for each topic and a random assortment should be used every time a box is clicked. All choices should be appropriate for a 10 year-old user. The title of the activity is "Story Spark."
