The best paraphrase for the first paragraph is: "After school, Jade tells her cousin Karla to try out for the step team" This is mainly what the first paragraph is concerned with.
After school, Jade tells her cousin Karla to try out for the step team.
In the first paragraph Jade is trying to convice Karla to join the step team. It goes on to talk about how Karla is nervous about trying out because she doesn't want to mess up in front of others. While Jade cares about Karla, it isn't the most important part of the paragraph.
