Which sentence from the passage best supports the theme of "appearances can be deceiving"?

**Passage: "Lucky"**

Chelsea couldn't believe her luck. Her teacher had assigned a class project and she was paired with Susie. At school, Susie was always a studious student who was very helpful to others. Chelsea knew that she could always count on Susie to help anyone in the class if they were trying to learn something new. It gave her great joy and comfort to be her partner on this project.

A few days later, both girls met at Susie’s house. The project was a presentation about their state, and students were asked to give as many facts about the state as possible. It turned out that Susie had moved only a year ago to their state so she was the one who needed help this time. Chelsea had always loved social studies, and she knew lots of facts already. She was able to contribute more to the conversation than Susie and that was very helpful to Susie. Susie also helped Chelsea find ways to locate the rest of the information they did not know.

That day, Chelsea and Susie learned a lot about each other and became good friends. Chelsea felt that she had the chance to get to know Susie more personally out of school. It turns out that Susie also thought that Chelsea was very helpful at school and she admired her very much. This rapport helped the girls deliver an excellent presentation that the rest of the students and the teacher enjoyed.
